| clusterTrustBundle | object | ❌ | ClusterTrustBundle allows a pod to access the .spec.trustBundle field of ClusterTrustBundle objects in an auto-updating file. Alpha, gated by the ClusterTrustBundleProjection feature gate. ClusterTrustBundle objects can either be selected by name, or by the combination of signer name and a label selector. Kubelet performs aggressive normalization of the PEM contents written into the pod filesystem. Esoteric PEM features such as inter-block comments and block headers are stripped. Certificates are deduplicated. The ordering of certificates within the file is arbitrary, and Kubelet may change the order over time. |
| configMap | object | ❌ | configMap information about the configMap data to project |
| downwardAPI | object | ❌ | downwardAPI information about the downwardAPI data to project |
| podCertificate | object | ❌ | Projects an auto-rotating credential bundle (private key and certificate chain) that the pod can use either as a TLS client or server. Kubelet generates a private key and uses it to send a PodCertificateRequest to the named signer. Once the signer approves the request and issues a certificate chain, Kubelet writes the key and certificate chain to the pod filesystem. The pod does not start until certificates have been issued for each podCertificate projected volume source in its spec. Kubelet will begin trying to rotate the certificate at the time indicated by the signer using the PodCertificateRequest.Status.BeginRefreshAt timestamp. Kubelet can write a single file, indicated by the credentialBundlePath field, or separate files, indicated by the keyPath and certificateChainPath fields. The credential bundle is a single file in PEM format. The first PEM entry is the private key (in PKCS#8 format), and the remaining PEM entries are the certificate chain issued by the signer (typically, signers will return their certificate chain in leaf-to-root order). Prefer using the credential bundle format, since your application code can read it atomically. If you use keyPath and certificateChainPath, your application must make two separate file reads. If these coincide with a certificate rotation, it is possible that the private key and leaf certificate you read may not correspond to each other. Your application will need to check for this condition, and re-read until they are consistent. The named signer controls chooses the format of the certificate it issues; consult the signer implementation's documentation to learn how to use the certificates it issues. |
| secret | object | ❌ | secret information about the secret data to project |
| serviceAccountToken | object | ❌ | serviceAccountToken is information about the serviceAccountToken data to project |

Projects an auto-rotating credential bundle (private key and certificate chain) that the pod can use either as a TLS client or server. Kubelet generates a private key and uses it to send a PodCertificateRequest to the named signer. Once the signer approves the request and issues a certificate chain, Kubelet writes the key and certificate chain to the pod filesystem. The pod does not start until certificates have been issued for each podCertificate projected volume source in its spec. Kubelet will begin trying to rotate the certificate at the time indicated by the signer using the PodCertificateRequest.Status.BeginRefreshAt timestamp. Kubelet can write a single file, indicated by the credentialBundlePath field, or separate files, indicated by the keyPath and certificateChainPath fields. The credential bundle is a single file in PEM format. The first PEM entry is the private key (in PKCS#8 format), and the remaining PEM entries are the certificate chain issued by the signer (typically, signers will return their certificate chain in leaf-to-root order). Prefer using the credential bundle format, since your application code can read it atomically. If you use keyPath and certificateChainPath, your application must make two separate file reads. If these coincide with a certificate rotation, it is possible that the private key and leaf certificate you read may not correspond to each other. Your application will need to check for this condition, and re-read until they are consistent. The named signer controls chooses the format of the certificate it issues; consult the signer implementation's documentation to learn how to use the certificates it issues.
| name | type | required | description |
|---|
| certificateChainPath | string | ❌ | Write the certificate chain at this path in the projected volume. Most applications should use credentialBundlePath. When using keyPath and certificateChainPath, your application needs to check that the key and leaf certificate are consistent, because it is possible to read the files mid-rotation. |
| credentialBundlePath | string | ❌ | Write the credential bundle at this path in the projected volume. The credential bundle is a single file that contains multiple PEM blocks. The first PEM block is a PRIVATE KEY block, containing a PKCS#8 private key. The remaining blocks are CERTIFICATE blocks, containing the issued certificate chain from the signer (leaf and any intermediates). Using credentialBundlePath lets your Pod's application code make a single atomic read that retrieves a consistent key and certificate chain. If you project them to separate files, your application code will need to additionally check that the leaf certificate was issued to the key. |
| keyPath | string | ❌ | Write the key at this path in the projected volume. Most applications should use credentialBundlePath. When using keyPath and certificateChainPath, your application needs to check that the key and leaf certificate are consistent, because it is possible to read the files mid-rotation. |
| keyType | string | ✅ | The type of keypair Kubelet will generate for the pod. Valid values are "RSA3072", "RSA4096", "ECDSAP256", "ECDSAP384", "ECDSAP521", and "ED25519". |
| maxExpirationSeconds | integer | ❌ | maxExpirationSeconds is the maximum lifetime permitted for the certificate. Kubelet copies this value verbatim into the PodCertificateRequests it generates for this projection. If omitted, kube-apiserver will set it to 86400(24 hours). kube-apiserver will reject values shorter than 3600 (1 hour). The maximum allowable value is 7862400 (91 days). The signer implementation is then free to issue a certificate with any lifetime shorter than MaxExpirationSeconds, but no shorter than 3600 seconds (1 hour). This constraint is enforced by kube-apiserver. kubernetes.io signers will never issue certificates with a lifetime longer than 24 hours. |
| signerName | string | ✅ | Kubelet's generated CSRs will be addressed to this signer. |

serviceAccountToken is information about the serviceAccountToken data to project
| name | type | required | description |
|---|
| audience | string | ❌ | audience is the intended audience of the token. A recipient of a token must identify itself with an identifier specified in the audience of the token, and otherwise should reject the token. The audience defaults to the identifier of the apiserver. |
| expirationSeconds | integer | ❌ | expirationSeconds is the requested duration of validity of the service account token. As the token approaches expiration, the kubelet volume plugin will proactively rotate the service account token. The kubelet will start trying to rotate the token if the token is older than 80 percent of its time to live or if the token is older than 24 hours.Defaults to 1 hour and must be at least 10 minutes. |
| path | string | ✅ | path is the path relative to the mount point of the file to project the token into. |

Tolerations of a PgBackRest repo host pod. Changing this value causes a restart. More info: https://kubernetes.io/docs/concepts/scheduling-eviction/taint-and-toleration
| name | type | required | description |
|---|
| effect | string | ❌ | Effect indicates the taint effect to match. Empty means match all taint effects. When specified, allowed values are NoSchedule, PreferNoSchedule and NoExecute. |
| key | string | ❌ | Key is the taint key that the toleration applies to. Empty means match all taint keys. If the key is empty, operator must be Exists; this combination means to match all values and all keys. |
| operator | string | ❌ | Operator represents a key's relationship to the value. Valid operators are Exists and Equal. Defaults to Equal. Exists is equivalent to wildcard for value, so that a pod can tolerate all taints of a particular category. |
| tolerationSeconds | integer | ❌ | TolerationSeconds represents the period of time the toleration (which must be of effect NoExecute, otherwise this field is ignored) tolerates the taint. By default, it is not set, which means tolerate the taint forever (do not evict). Zero and negative values will be treated as 0 (evict immediately) by the system. |
| value | string | ❌ | Value is the taint value the toleration matches to. If the operator is Exists, the value should be empty, otherwise just a regular string. |
Topology spread constraints of a Dedicated repo host pod. Changing this value causes the repo host to restart. More info: https://kubernetes.io/docs/concepts/workloads/pods/pod-topology-spread-constraints/
| name | type | required | description |
|---|
| labelSelector | object | ❌ | LabelSelector is used to find matching pods. Pods that match this label selector are counted to determine the number of pods in their corresponding topology domain. |
| matchLabelKeys | []string | ❌ | MatchLabelKeys is a set of pod label keys to select the pods over which spreading will be calculated. The keys are used to lookup values from the incoming pod labels, those key-value labels are ANDed with labelSelector to select the group of existing pods over which spreading will be calculated for the incoming pod. The same key is forbidden to exist in both MatchLabelKeys and LabelSelector. MatchLabelKeys cannot be set when LabelSelector isn't set. Keys that don't exist in the incoming pod labels will be ignored. A null or empty list means only match against labelSelector. This is a beta field and requires the MatchLabelKeysInPodTopologySpread feature gate to be enabled (enabled by default). |
| maxSkew | integer | ✅ | MaxSkew describes the degree to which pods may be unevenly distributed. When whenUnsatisfiable=DoNotSchedule, it is the maximum permitted difference between the number of matching pods in the target topology and the global minimum. The global minimum is the minimum number of matching pods in an eligible domain or zero if the number of eligible domains is less than MinDomains. For example, in a 3-zone cluster, MaxSkew is set to 1, and pods with the same labelSelector spread as 2/2/1: In this case, the global minimum is 1. | zone1 | zone2 | zone3 | | P P | P P | P | - if MaxSkew is 1, incoming pod can only be scheduled to zone3 to become 2/2/2; scheduling it onto zone1(zone2) would make the ActualSkew(3-1) on zone1(zone2) violate MaxSkew(1). - if MaxSkew is 2, incoming pod can be scheduled onto any zone. When whenUnsatisfiable=ScheduleAnyway, it is used to give higher precedence to topologies that satisfy it. It's a required field. Default value is 1 and 0 is not allowed. |
| minDomains | integer | ❌ | MinDomains indicates a minimum number of eligible domains. When the number of eligible domains with matching topology keys is less than minDomains, Pod Topology Spread treats "global minimum" as 0, and then the calculation of Skew is performed. And when the number of eligible domains with matching topology keys equals or greater than minDomains, this value has no effect on scheduling. As a result, when the number of eligible domains is less than minDomains, scheduler won't schedule more than maxSkew Pods to those domains. If value is nil, the constraint behaves as if MinDomains is equal to 1. Valid values are integers greater than 0. When value is not nil, WhenUnsatisfiable must be DoNotSchedule. For example, in a 3-zone cluster, MaxSkew is set to 2, MinDomains is set to 5 and pods with the same labelSelector spread as 2/2/2: | zone1 | zone2 | zone3 | | P P | P P | P P | The number of domains is less than 5(MinDomains), so "global minimum" is treated as 0. In this situation, new pod with the same labelSelector cannot be scheduled, because computed skew will be 3(3 - 0) if new Pod is scheduled to any of the three zones, it will violate MaxSkew. |
| nodeAffinityPolicy | string | ❌ | NodeAffinityPolicy indicates how we will treat Pod's nodeAffinity/nodeSelector when calculating pod topology spread skew. Options are: - Honor: only nodes matching nodeAffinity/nodeSelector are included in the calculations. - Ignore: nodeAffinity/nodeSelector are ignored. All nodes are included in the calculations. If this value is nil, the behavior is equivalent to the Honor policy. |
| nodeTaintsPolicy | string | ❌ | NodeTaintsPolicy indicates how we will treat node taints when calculating pod topology spread skew. Options are: - Honor: nodes without taints, along with tainted nodes for which the incoming pod has a toleration, are included. - Ignore: node taints are ignored. All nodes are included. If this value is nil, the behavior is equivalent to the Ignore policy. |
| topologyKey | string | ✅ | TopologyKey is the key of node labels. Nodes that have a label with this key and identical values are considered to be in the same topology. We consider each <key, value> as a "bucket", and try to put balanced number of pods into each bucket. We define a domain as a particular instance of a topology. Also, we define an eligible domain as a domain whose nodes meet the requirements of nodeAffinityPolicy and nodeTaintsPolicy. e.g. If TopologyKey is "kubernetes.io/hostname", each Node is a domain of that topology. And, if TopologyKey is "topology.kubernetes.io/zone", each zone is a domain of that topology. It's a required field. |
| whenUnsatisfiable | string | ✅ | WhenUnsatisfiable indicates how to deal with a pod if it doesn't satisfy the spread constraint. - DoNotSchedule (default) tells the scheduler not to schedule it. - ScheduleAnyway tells the scheduler to schedule the pod in any location, but giving higher precedence to topologies that would help reduce the skew. A constraint is considered "Unsatisfiable" for an incoming pod if and only if every possible node assignment for that pod would violate "MaxSkew" on some topology. For example, in a 3-zone cluster, MaxSkew is set to 1, and pods with the same labelSelector spread as 3/1/1: | zone1 | zone2 | zone3 | | P P P | P | P | If WhenUnsatisfiable is set to DoNotSchedule, incoming pod can only be scheduled to zone2(zone3) to become 3/2/1(3/1/2) as ActualSkew(2-1) on zone2(zone3) satisfies MaxSkew(1). In other words, the cluster can still be imbalanced, but scheduler won't make it more imbalanced. It's a required field. |

IfNotPresent: the kubelet pulls if the reference isn't already present on disk. Container creation will fail if the reference isn't present and the pull fails. Defaults to Always if :latest tag is specified, or IfNotPresent otherwise. |

| dataSourceRef | object | ❌ | dataSourceRef specifies the object from which to populate the volume with data, if a non-empty volume is desired. This may be any object from a non-empty API group (non core object) or a PersistentVolumeClaim object. When this field is specified, volume binding will only succeed if the type of the specified object matches some installed volume populator or dynamic provisioner. This field will replace the functionality of the dataSource field and as such if both fields are non-empty, they must have the same value. For backwards compatibility, when namespace isn't specified in dataSourceRef, both fields (dataSource and dataSourceRef) will be set to the same value automatically if one of them is empty and the other is non-empty. When namespace is specified in dataSourceRef, dataSource isn't set to the same value and must be empty. There are three important differences between dataSource and dataSourceRef: * While dataSource only allows two specific types of objects, dataSourceRef allows any non-core object, as well as PersistentVolumeClaim objects. * While dataSource ignores disallowed values (dropping them), dataSourceRef preserves all values, and generates an error if a disallowed value is specified. * While dataSource only allows local objects, dataSourceRef allows objects in any namespaces.

| podCertificate | object | ❌ | Projects an auto-rotating credential bundle (private key and certificate chain) that the pod can use either as a TLS client or server. Kubelet generates a private key and uses it to send a PodCertificateRequest to the named signer. Once the signer approves the request and issues a certificate chain, Kubelet writes the key and certificate chain to the pod filesystem. The pod does not start until certificates have been issued for each podCertificate projected volume source in its spec. Kubelet will begin trying to rotate the certificate at the time indicated by the signer using the PodCertificateRequest.Status.BeginRefreshAt timestamp. Kubelet can write a single file, indicated by the credentialBundlePath field, or separate files, indicated by the keyPath and certificateChainPath fields. The credential bundle is a single file in PEM format. The first PEM entry is the private key (in PKCS#8 format), and the remaining PEM entries are the certificate chain issued by the signer (typically, signers will return their certificate chain in leaf-to-root order). Prefer using the credential bundle format, since your application code can read it atomically. If you use keyPath and certificateChainPath, your application must make two separate file reads. If these coincide with a certificate rotation, it is possible that the private key and leaf certificate you read may not correspond to each other. Your application will need to check for this condition, and re-read until they are consistent. The named signer controls chooses the format of the certificate it issues; consult the signer implementation's documentation to learn how to use the certificates it issues. |

Projects an auto-rotating credential bundle (private key and certificate chain) that the pod can use either as a TLS client or server. Kubelet generates a private key and uses it to send a PodCertificateRequest to the named signer. Once the signer approves the request and issues a certificate chain, Kubelet writes the key and certificate chain to the pod filesystem. The pod does not start until certificates have been issued for each podCertificate projected volume source in its spec. Kubelet will begin trying to rotate the certificate at the time indicated by the signer using the PodCertificateRequest.Status.BeginRefreshAt timestamp. Kubelet can write a single file, indicated by the credentialBundlePath field, or separate files, indicated by the keyPath and certificateChainPath fields. The credential bundle is a single file in PEM format. The first PEM entry is the private key (in PKCS#8 format), and the remaining PEM entries are the certificate chain issued by the signer (typically, signers will return their certificate chain in leaf-to-root order). Prefer using the credential bundle format, since your application code can read it atomically. If you use keyPath and certificateChainPath, your application must make two separate file reads. If these coincide with a certificate rotation, it is possible that the private key and leaf certificate you read may not correspond to each other. Your application will need to check for this condition, and re-read until they are consistent. The named signer controls chooses the format of the certificate it issues; consult the signer implementation's documentation to learn how to use the certificates it issues.
| name | type | required | description |
|---|
| certificateChainPath | string | ❌ | Write the certificate chain at this path in the projected volume. Most applications should use credentialBundlePath. When using keyPath and certificateChainPath, your application needs to check that the key and leaf certificate are consistent, because it is possible to read the files mid-rotation. |
| credentialBundlePath | string | ❌ | Write the credential bundle at this path in the projected volume. The credential bundle is a single file that contains multiple PEM blocks. The first PEM block is a PRIVATE KEY block, containing a PKCS#8 private key. The remaining blocks are CERTIFICATE blocks, containing the issued certificate chain from the signer (leaf and any intermediates). Using credentialBundlePath lets your Pod's application code make a single atomic read that retrieves a consistent key and certificate chain. If you project them to separate files, your application code will need to additionally check that the leaf certificate was issued to the key. |
| keyPath | string | ❌ | Write the key at this path in the projected volume. Most applications should use credentialBundlePath. When using keyPath and certificateChainPath, your application needs to check that the key and leaf certificate are consistent, because it is possible to read the files mid-rotation. |
| keyType | string | ✅ | The type of keypair Kubelet will generate for the pod. Valid values are "RSA3072", "RSA4096", "ECDSAP256", "ECDSAP384", "ECDSAP521", and "ED25519". |
| maxExpirationSeconds | integer | ❌ | maxExpirationSeconds is the maximum lifetime permitted for the certificate. Kubelet copies this value verbatim into the PodCertificateRequests it generates for this projection. If omitted, kube-apiserver will set it to 86400(24 hours). kube-apiserver will reject values shorter than 3600 (1 hour). The maximum allowable value is 7862400 (91 days). The signer implementation is then free to issue a certificate with any lifetime shorter than MaxExpirationSeconds, but no shorter than 3600 seconds (1 hour). This constraint is enforced by kube-apiserver. kubernetes.io signers will never issue certificates with a lifetime longer than 24 hours. |
| signerName | string | ✅ | Kubelet's generated CSRs will be addressed to this signer. |

The pod does not start until certificates have been issued for each podCertificate projected volume source in its spec. Kubelet will begin trying to rotate the certificate at the time indicated by the signer using the PodCertificateRequest.Status.BeginRefreshAt timestamp. Kubelet can write a single file, indicated by the credentialBundlePath field, or separate files, indicated by the keyPath and certificateChainPath fields. The credential bundle is a single file in PEM format. The first PEM entry is the private key (in PKCS#8 format), and the remaining PEM entries are the certificate chain issued by the signer (typically, signers will return their certificate chain in leaf-to-root order). Prefer using the credential bundle format, since your application code can read it atomically. If you use keyPath and certificateChainPath, your application must make two separate file reads. If these coincide with a certificate rotation, it is possible that the private key and leaf certificate you read may not correspond to each other. Your application will need to check for this condition, and re-read until they are consistent.

Projects an auto-rotating credential bundle (private key and certificate chain) that the pod can use either as a TLS client or server. Kubelet generates a private key and uses it to send a PodCertificateRequest to the named signer. Once the signer approves the request and issues a certificate chain, Kubelet writes the key and certificate chain to the pod filesystem. The pod does not start until certificates have been issued for each podCertificate projected volume source in its spec. Kubelet will begin trying to rotate the certificate at the time indicated by the signer using the PodCertificateRequest.Status.BeginRefreshAt timestamp. Kubelet can write a single file, indicated by the credentialBundlePath field, or separate files, indicated by the keyPath and certificateChainPath fields. The credential bundle is a single file in PEM format.

| credentialBundlePath | string | ❌ | Write the credential bundle at this path in the projected volume. The credential bundle is a single file that contains multiple PEM blocks. The first PEM block is a PRIVATE KEY block, containing a PKCS#8 private key. The remaining blocks are CERTIFICATE blocks, containing the issued certificate chain from the signer (leaf and any intermediates). Using credentialBundlePath lets your Pod's application code make a single atomic read that retrieves a consistent key and certificate chain. If you project them to separate files, your application code will need to additionally check that the leaf certificate was issued to the key. |
| keyPath | string | ❌ | Write the key at this path in the projected volume. Most applications should use credentialBundlePath. When using keyPath and certificateChainPath, your application needs to check that the key and leaf certificate are consistent, because it is possible to read the files mid-rotation. |
| keyType | string | ✅ | The type of keypair Kubelet will generate for the pod. Valid values are "RSA3072", "RSA4096", "ECDSAP256", "ECDSAP384", "ECDSAP521", and "ED25519". |
| maxExpirationSeconds | integer | ❌ | maxExpirationSeconds is the maximum lifetime permitted for the certificate. Kubelet copies this value verbatim into the PodCertificateRequests it generates for this projection. If omitted, kube-apiserver will set it to 86400(24 hours). kube-apiserver will reject values shorter than 3600 (1 hour). The maximum allowable value is 7862400 (91 days). The signer implementation is then free to issue a certificate with any lifetime shorter than MaxExpirationSeconds, but no shorter than 3600 seconds (1 hour). This constraint is enforced by kube-apiserver. kubernetes.io signers will never issue certificates with a lifetime longer than 24 hours. |
| signerName | string | ✅ | Kubelet's generated CSRs will be addressed to this signer. |

| autoGrow | object | ❌ | AutoGrowSpec provides options to tune volume auto-growing behavior. Auto grow requires that a limit be set on the PVC. |
| dataSource | object | ❌ | dataSource field can be used to specify either: * An existing VolumeSnapshot object (snapshot.storage.k8s.io/VolumeSnapshot) * An existing PVC (PersistentVolumeClaim) If the provisioner or an external controller can support the specified data source, it will create a new volume based on the contents of the specified data source. When the AnyVolumeDataSource feature gate is enabled, dataSource contents will be copied to dataSourceRef, and dataSourceRef contents will be copied to dataSource when dataSourceRef.namespace is not specified. If the namespace is specified, then dataSourceRef will not be copied to dataSource. |
| dataSourceRef | object | ❌ | dataSourceRef specifies the object from which to populate the volume with data, if a non-empty volume is desired. This may be any object from a non-empty API group (non core object) or a PersistentVolumeClaim object. When this field is specified, volume binding will only succeed if the type of the specified object matches some installed volume populator or dynamic provisioner. This field will replace the functionality of the dataSource field and as such if both fields are non-empty, they must have the same value. For backwards compatibility, when namespace isn't specified in dataSourceRef, both fields (dataSource and dataSourceRef) will be set to the same value automatically if one of them is empty and the other is non-empty. When namespace is specified in dataSourceRef, dataSource isn't set to the same value and must be empty. There are three important differences between dataSource and dataSourceRef: * While dataSource only allows two specific types of objects, dataSourceRef allows any non-core object, as well as PersistentVolumeClaim objects. * While dataSource ignores disallowed values (dropping them), dataSourceRef preserves all values, and generates an error if a disallowed value is specified. * While dataSource only allows local objects, dataSourceRef allows objects in any namespaces. (Beta) Using this field requires the AnyVolumeDataSource feature gate to be enabled. (Alpha) Using the namespace field of dataSourceRef requires the CrossNamespaceVolumeDataSource feature gate to be enabled. |

| volumeAttributesClassName | string | ❌ | volumeAttributesClassName may be used to set the VolumeAttributesClass used by this claim. If specified, the CSI driver will create or update the volume with the attributes defined in the corresponding VolumeAttributesClass. This has a different purpose than storageClassName, it can be changed after the claim is created. An empty string or nil value indicates that no VolumeAttributesClass will be applied to the claim. If the claim enters an Infeasible error state, this field can be reset to its previous value (including nil) to cancel the modification. If the resource referred to by volumeAttributesClass does not exist, this PersistentVolumeClaim will be set to a Pending state, as reflected by the modifyVolumeStatus field, until such as a resource exists.

dataSourceRef specifies the object from which to populate the volume with data, if a non-empty volume is desired. This may be any object from a non-empty API group (non core object) or a PersistentVolumeClaim object. When this field is specified, volume binding will only succeed if the type of the specified object matches some installed volume populator or dynamic provisioner.

| operator | string | ❌ | Operator represents a key's relationship to the value. Valid operators are Exists and Equal. Defaults to Equal. Exists is equivalent to wildcard for value, so that a pod can tolerate all taints of a particular category. |
| tolerationSeconds | integer | ❌ | TolerationSeconds represents the period of time the toleration (which must be of effect NoExecute, otherwise this field is ignored) tolerates the taint. By default, it is not set, which means tolerate the taint forever (do not evict). Zero and negative values will be treated as 0 (evict immediately) by the system. |

Container creation will fail If the pull fails. Never: the kubelet never pulls the reference and only uses a local image or artifact. Container creation will fail if the reference isn't present. IfNotPresent: the kubelet pulls if the reference isn't already present on disk. Container creation will fail if the reference isn't present and the pull fails. Defaults to Always if :latest tag is specified, or IfNotPresent otherwise. |
| reference | string | ✅ | Required: Image or artifact reference to be used. Behaves in the same way as pod.spec.containers[*].image. Pull secrets will be assembled in the same way as for the container image by looking up node credentials, SA image pull secrets, and pod spec image pull secrets.

| restartPolicy | string | ❌ | RestartPolicy defines the restart behavior of individual containers in a pod. This overrides the pod-level restart policy. When this field is not specified, the restart behavior is defined by the Pod's restart policy and the container type. Additionally, setting the RestartPolicy as "Always" for the init container will have the following effect: this init container will be continually restarted on exit until all regular containers have terminated. Once all regular containers have completed, all init containers with restartPolicy "Always" will be shut down. This lifecycle differs from normal init containers and is often referred to as a "sidecar" container. Although this init container still starts in the init container sequence, it does not wait for the container to complete before proceeding to the next init container. Instead, the next init container starts immediately after this init container is started, or after any startupProbe has successfully completed. |
| restartPolicyRules | []object | ❌ | Represents a list of rules to be checked to determine if the container should be restarted on exit. The rules are evaluated in order. Once a rule matches a container exit condition, the remaining rules are ignored. If no rule matches the container exit condition, the Container-level restart policy determines the whether the container is restarted or not. Constraints on the rules: - At most 20 rules are allowed. - Rules can have the same action. - Identical rules are not forbidden in validations. When rules are specified, container MUST set RestartPolicy explicitly even it if matches the Pod's RestartPolicy. |
| securityContext | object | ❌ | SecurityContext defines the security options the container should be run with. If set, the fields of SecurityContext override the equivalent fields of PodSecurityContext. More info: https://kubernetes.io/docs/tasks/configure-pod-container/security-context/ |
| startupProbe | object | ❌ | StartupProbe indicates that the Pod has successfully initialized. If specified, no other probes are executed until this completes successfully. If this probe fails, the Pod will be restarted, just as if the livenessProbe failed. This can be used to provide different probe parameters at the beginning of a Pod's lifecycle, when it might take a long time to load data or warm a cache, than during steady-state operation. This cannot be updated. More info: https://kubernetes.io/docs/concepts/workloads/pods/pod-lifecycle#container-probes |
| stdin | boolean | ❌ | Whether this container should allocate a buffer for stdin in the container runtime. If this is not set, reads from stdin in the container will always result in EOF. Default is false. |
| stdinOnce | boolean | ❌ | Whether the container runtime should close the stdin channel after it has been opened by a single attach. When stdin is true the stdin stream will remain open across multiple attach sessions. If stdinOnce is set to true, stdin is opened on container start, is empty until the first client attaches to stdin, and then remains open and accepts data until the client disconnects, at which time stdin is closed and remains closed until the container is restarted. If this flag is false, a container processes that reads from stdin will never receive an EOF. Default is false |
| terminationMessagePath | string | ❌ | Optional: Path at which the file to which the container's termination message will be written is mounted into the container's filesystem.

| readOnly | boolean | ❌ | Mounted read-only if true, read-write otherwise (false or unspecified). Defaults to false. |
| recursiveReadOnly | string | ❌ | RecursiveReadOnly specifies whether read-only mounts should be handled recursively. If ReadOnly is false, this field has no meaning and must be unspecified. If ReadOnly is true, and this field is set to Disabled, the mount is not made recursively read-only. If this field is set to IfPossible, the mount is made recursively read-only, if it is supported by the container runtime. If this field is set to Enabled, the mount is made recursively read-only if it is supported by the container runtime, otherwise the pod will not be started and an error will be generated to indicate the reason. If this field is set to IfPossible or Enabled, MountPropagation must be set to None (or be unspecified, which defaults to None).

When the AnyVolumeDataSource feature gate is enabled, dataSource contents will be copied to dataSourceRef, and dataSourceRef contents will be copied to dataSource when dataSourceRef.namespace is not specified. If the namespace is specified, then dataSourceRef will not be copied to dataSource. |
| dataSourceRef | object | ❌ | dataSourceRef specifies the object from which to populate the volume with data, if a non-empty volume is desired. This may be any object from a non-empty API group (non core object) or a PersistentVolumeClaim object. When this field is specified, volume binding will only succeed if the type of the specified object matches some installed volume populator or dynamic provisioner. This field will replace the functionality of the dataSource field and as such if both fields are non-empty, they must have the same value. For backwards compatibility, when namespace isn't specified in dataSourceRef, both fields (dataSource and dataSourceRef) will be set to the same value automatically if one of them is empty and the other is non-empty. When namespace is specified in dataSourceRef, dataSource isn't set to the same value and must be empty. There are three important differences between dataSource and dataSourceRef: * While dataSource only allows two specific types of objects, dataSourceRef allows any non-core object, as well as PersistentVolumeClaim objects. * While dataSource ignores disallowed values (dropping them), dataSourceRef preserves all values, and generates an error if a disallowed value is specified. * While dataSource only allows local objects, dataSourceRef allows objects in any namespaces. (Beta) Using this field requires the AnyVolumeDataSource feature gate to be enabled. (Alpha) Using the namespace field of dataSourceRef requires the CrossNamespaceVolumeDataSource feature gate to be enabled. |

If specified, the CSI driver will create or update the volume with the attributes defined in the corresponding VolumeAttributesClass. This has a different purpose than storageClassName, it can be changed after the claim is created. An empty string or nil value indicates that no VolumeAttributesClass will be applied to the claim. If the claim enters an Infeasible error state, this field can be reset to its previous value (including nil) to cancel the modification. If the resource referred to by volumeAttributesClass does not exist, this PersistentVolumeClaim will be set to a Pending state, as reflected by the modifyVolumeStatus field, until such as a resource exists.

| tolerationSeconds | integer | ❌ | TolerationSeconds represents the period of time the toleration (which must be of effect NoExecute, otherwise this field is ignored) tolerates the taint. By default, it is not set, which means tolerate the taint forever (do not evict). Zero and negative values will be treated as 0 (evict immediately) by the system. |
| value | string | ❌ | Value is the taint value the toleration matches to. If the operator is Exists, the value should be empty, otherwise just a regular string. |
Topology spread constraints of a PostgreSQL pod. Changing this value causes PostgreSQL to restart. More info: https://kubernetes.io/docs/concepts/workloads/pods/pod-topology-spread-constraints/
| name | type | required | description |
|---|
| labelSelector | object | ❌ | LabelSelector is used to find matching pods. Pods that match this label selector are counted to determine the number of pods in their corresponding topology domain. |
| matchLabelKeys | []string | ❌ | MatchLabelKeys is a set of pod label keys to select the pods over which spreading will be calculated. The keys are used to lookup values from the incoming pod labels, those key-value labels are ANDed with labelSelector to select the group of existing pods over which spreading will be calculated for the incoming pod. The same key is forbidden to exist in both MatchLabelKeys and LabelSelector. MatchLabelKeys cannot be set when LabelSelector isn't set. Keys that don't exist in the incoming pod labels will be ignored. A null or empty list means only match against labelSelector. This is a beta field and requires the MatchLabelKeysInPodTopologySpread feature gate to be enabled (enabled by default). |
| maxSkew | integer | ✅ | MaxSkew describes the degree to which pods may be unevenly distributed. When whenUnsatisfiable=DoNotSchedule, it is the maximum permitted difference between the number of matching pods in the target topology and the global minimum. The global minimum is the minimum number of matching pods in an eligible domain or zero if the number of eligible domains is less than MinDomains. For example, in a 3-zone cluster, MaxSkew is set to 1, and pods with the same labelSelector spread as 2/2/1: In this case, the global minimum is 1. | zone1 | zone2 | zone3 | | P P | P P | P | - if MaxSkew is 1, incoming pod can only be scheduled to zone3 to become 2/2/2; scheduling it onto zone1(zone2) would make the ActualSkew(3-1) on zone1(zone2) violate MaxSkew(1). - if MaxSkew is 2, incoming pod can be scheduled onto any zone. When whenUnsatisfiable=ScheduleAnyway, it is used to give higher precedence to topologies that satisfy it. It's a required field. Default value is 1 and 0 is not allowed. |
| minDomains | integer | ❌ | MinDomains indicates a minimum number of eligible domains. When the number of eligible domains with matching topology keys is less than minDomains, Pod Topology Spread treats "global minimum" as 0, and then the calculation of Skew is performed. And when the number of eligible domains with matching topology keys equals or greater than minDomains, this value has no effect on scheduling. As a result, when the number of eligible domains is less than minDomains, scheduler won't schedule more than maxSkew Pods to those domains. If value is nil, the constraint behaves as if MinDomains is equal to 1. Valid values are integers greater than 0. When value is not nil, WhenUnsatisfiable must be DoNotSchedule. For example, in a 3-zone cluster, MaxSkew is set to 2, MinDomains is set to 5 and pods with the same labelSelector spread as 2/2/2: | zone1 | zone2 | zone3 | | P P | P P | P P | The number of domains is less than 5(MinDomains), so "global minimum" is treated as 0. In this situation, new pod with the same labelSelector cannot be scheduled, because computed skew will be 3(3 - 0) if new Pod is scheduled to any of the three zones, it will violate MaxSkew. |
| nodeAffinityPolicy | string | ❌ | NodeAffinityPolicy indicates how we will treat Pod's nodeAffinity/nodeSelector when calculating pod topology spread skew. Options are: - Honor: only nodes matching nodeAffinity/nodeSelector are included in the calculations. - Ignore: nodeAffinity/nodeSelector are ignored. All nodes are included in the calculations. If this value is nil, the behavior is equivalent to the Honor policy. |
| nodeTaintsPolicy | string | ❌ | NodeTaintsPolicy indicates how we will treat node taints when calculating pod topology spread skew. Options are: - Honor: nodes without taints, along with tainted nodes for which the incoming pod has a toleration, are included. - Ignore: node taints are ignored. All nodes are included. If this value is nil, the behavior is equivalent to the Ignore policy. |
| topologyKey | string | ✅ | TopologyKey is the key of node labels. Nodes that have a label with this key and identical values are considered to be in the same topology. We consider each <key, value> as a "bucket", and try to put balanced number of pods into each bucket. We define a domain as a particular instance of a topology. Also, we define an eligible domain as a domain whose nodes meet the requirements of nodeAffinityPolicy and nodeTaintsPolicy. e.g. If TopologyKey is "kubernetes.io/hostname", each Node is a domain of that topology. And, if TopologyKey is "topology.kubernetes.io/zone", each zone is a domain of that topology. It's a required field. |
| whenUnsatisfiable | string | ✅ | WhenUnsatisfiable indicates how to deal with a pod if it doesn't satisfy the spread constraint. - DoNotSchedule (default) tells the scheduler not to schedule it. - ScheduleAnyway tells the scheduler to schedule the pod in any location, but giving higher precedence to topologies that would help reduce the skew. A constraint is considered "Unsatisfiable" for an incoming pod if and only if every possible node assignment for that pod would violate "MaxSkew" on some topology. For example, in a 3-zone cluster, MaxSkew is set to 1, and pods with the same labelSelector spread as 3/1/1: | zone1 | zone2 | zone3 | | P P P | P | P | If WhenUnsatisfiable is set to DoNotSchedule, incoming pod can only be scheduled to zone2(zone3) to become 3/2/1(3/1/2) as ActualSkew(2-1) on zone2(zone3) satisfies MaxSkew(1). In other words, the cluster can still be imbalanced, but scheduler won't make it more imbalanced. It's a required field. |

| podCertificate | object | ❌ | Projects an auto-rotating credential bundle (private key and certificate chain) that the pod can use either as a TLS client or server. Kubelet generates a private key and uses it to send a PodCertificateRequest to the named signer. Once the signer approves the request and issues a certificate chain, Kubelet writes the key and certificate chain to the pod filesystem. The pod does not start until certificates have been issued for each podCertificate projected volume source in its spec. Kubelet will begin trying to rotate the certificate at the time indicated by the signer using the PodCertificateRequest.Status.BeginRefreshAt timestamp. Kubelet can write a single file, indicated by the credentialBundlePath field, or separate files, indicated by the keyPath and certificateChainPath fields. The credential bundle is a single file in PEM format. The first PEM entry is the private key (in PKCS#8 format), and the remaining PEM entries are the certificate chain issued by the signer (typically, signers will return their certificate chain in leaf-to-root order). Prefer using the credential bundle format, since your application code can read it atomically. If you use keyPath and certificateChainPath, your application must make two separate file reads. If these coincide with a certificate rotation, it is possible that the private key and leaf certificate you read may not correspond to each other. Your application will need to check for this condition, and re-read until they are consistent. The named signer controls chooses the format of the certificate it issues; consult the signer implementation's documentation to learn how to use the certificates it issues. |

Projects an auto-rotating credential bundle (private key and certificate chain) that the pod can use either as a TLS client or server. Kubelet generates a private key and uses it to send a PodCertificateRequest to the named signer. Once the signer approves the request and issues a certificate chain, Kubelet writes the key and certificate chain to the pod filesystem. The pod does not start until certificates have been issued for each podCertificate projected volume source in its spec. Kubelet will begin trying to rotate the certificate at the time indicated by the signer using the PodCertificateRequest.Status.BeginRefreshAt timestamp. Kubelet can write a single file, indicated by the credentialBundlePath field, or separate files, indicated by the keyPath and certificateChainPath fields. The credential bundle is a single file in PEM format. The first PEM entry is the private key (in PKCS#8 format), and the remaining PEM entries are the certificate chain issued by the signer (typically, signers will return their certificate chain in leaf-to-root order). Prefer using the credential bundle format, since your application code can read it atomically. If you use keyPath and certificateChainPath, your application must make two separate file reads. If these coincide with a certificate rotation, it is possible that the private key and leaf certificate you read may not correspond to each other. Your application will need to check for this condition, and re-read until they are consistent. The named signer controls chooses the format of the certificate it issues; consult the signer implementation's documentation to learn how to use the certificates it issues.
| name | type | required | description |
|---|
| certificateChainPath | string | ❌ | Write the certificate chain at this path in the projected volume. Most applications should use credentialBundlePath. When using keyPath and certificateChainPath, your application needs to check that the key and leaf certificate are consistent, because it is possible to read the files mid-rotation. |
| credentialBundlePath | string | ❌ | Write the credential bundle at this path in the projected volume. The credential bundle is a single file that contains multiple PEM blocks. The first PEM block is a PRIVATE KEY block, containing a PKCS#8 private key. The remaining blocks are CERTIFICATE blocks, containing the issued certificate chain from the signer (leaf and any intermediates). Using credentialBundlePath lets your Pod's application code make a single atomic read that retrieves a consistent key and certificate chain. If you project them to separate files, your application code will need to additionally check that the leaf certificate was issued to the key. |
| keyPath | string | ❌ | Write the key at this path in the projected volume. Most applications should use credentialBundlePath. When using keyPath and certificateChainPath, your application needs to check that the key and leaf certificate are consistent, because it is possible to read the files mid-rotation. |
| keyType | string | ✅ | The type of keypair Kubelet will generate for the pod. Valid values are "RSA3072", "RSA4096", "ECDSAP256", "ECDSAP384", "ECDSAP521", and "ED25519". |
| maxExpirationSeconds | integer | ❌ | maxExpirationSeconds is the maximum lifetime permitted for the certificate. Kubelet copies this value verbatim into the PodCertificateRequests it generates for this projection. If omitted, kube-apiserver will set it to 86400(24 hours). kube-apiserver will reject values shorter than 3600 (1 hour). The maximum allowable value is 7862400 (91 days). The signer implementation is then free to issue a certificate with any lifetime shorter than MaxExpirationSeconds, but no shorter than 3600 seconds (1 hour). This constraint is enforced by kube-apiserver. kubernetes.io signers will never issue certificates with a lifetime longer than 24 hours. |
| signerName | string | ✅ | Kubelet's generated CSRs will be addressed to this signer. |

Projects an auto-rotating credential bundle (private key and certificate chain) that the pod can use either as a TLS client or server. Kubelet generates a private key and uses it to send a PodCertificateRequest to the named signer. Once the signer approves the request and issues a certificate chain, Kubelet writes the key and certificate chain to the pod filesystem. The pod does not start until certificates have been issued for each podCertificate projected volume source in its spec. Kubelet will begin trying to rotate the certificate at the time indicated by the signer using the PodCertificateRequest.Status.BeginRefreshAt timestamp. Kubelet can write a single file, indicated by the credentialBundlePath field, or separate files, indicated by the keyPath and certificateChainPath fields. The credential bundle is a single file in PEM format. The first PEM entry is the private key (in PKCS#8 format), and the remaining PEM entries are the certificate chain issued by the signer (typically, signers will return their certificate chain in leaf-to-root order). Prefer using the credential bundle format, since your application code can read it atomically. If you use keyPath and certificateChainPath, your application must make two separate file reads. If these coincide with a certificate rotation, it is possible that the private key and leaf certificate you read may not correspond to each other. Your application will need to check for this condition, and re-read until they are consistent. The named signer controls chooses the format of the certificate it issues; consult the signer implementation's documentation to learn how to use the certificates it issues.
| name | type | required | description |
|---|
| certificateChainPath | string | ❌ | Write the certificate chain at this path in the projected volume. Most applications should use credentialBundlePath. When using keyPath and certificateChainPath, your application needs to check that the key and leaf certificate are consistent, because it is possible to read the files mid-rotation. |
| credentialBundlePath | string | ❌ | Write the credential bundle at this path in the projected volume. The credential bundle is a single file that contains multiple PEM blocks. The first PEM block is a PRIVATE KEY block, containing a PKCS#8 private key. The remaining blocks are CERTIFICATE blocks, containing the issued certificate chain from the signer (leaf and any intermediates). Using credentialBundlePath lets your Pod's application code make a single atomic read that retrieves a consistent key and certificate chain. If you project them to separate files, your application code will need to additionally check that the leaf certificate was issued to the key. |
| keyPath | string | ❌ | Write the key at this path in the projected volume. Most applications should use credentialBundlePath. When using keyPath and certificateChainPath, your application needs to check that the key and leaf certificate are consistent, because it is possible to read the files mid-rotation. |
| keyType | string | ✅ | The type of keypair Kubelet will generate for the pod. Valid values are "RSA3072", "RSA4096", "ECDSAP256", "ECDSAP384", "ECDSAP521", and "ED25519". |
| maxExpirationSeconds | integer | ❌ | maxExpirationSeconds is the maximum lifetime permitted for the certificate. Kubelet copies this value verbatim into the PodCertificateRequests it generates for this projection. If omitted, kube-apiserver will set it to 86400(24 hours). kube-apiserver will reject values shorter than 3600 (1 hour). The maximum allowable value is 7862400 (91 days). The signer implementation is then free to issue a certificate with any lifetime shorter than MaxExpirationSeconds, but no shorter than 3600 seconds (1 hour). This constraint is enforced by kube-apiserver. kubernetes.io signers will never issue certificates with a lifetime longer than 24 hours. |
| signerName | string | ✅ | Kubelet's generated CSRs will be addressed to this signer. |

When there are multiple elements, the lists of nodes corresponding to each podAffinityTerm are intersected, i.e. all terms must be satisfied. |
The scheduler will prefer to schedule pods to nodes that satisfy the anti-affinity expressions specified by this field, but it may choose a node that violates one or more of the expressions. The node that is most preferred is the one with the greatest sum of weights, i.e. for each node that meets all of the scheduling requirements (resource request, requiredDuringScheduling anti-affinity expressions, etc.), compute a sum by iterating through the elements of this field and subtracting "weight" from the sum if the node has pods which matches the corresponding podAffinityTerm; the node(s) with the highest sum are the most preferred.

| podCertificate | object | ❌ | Projects an auto-rotating credential bundle (private key and certificate chain) that the pod can use either as a TLS client or server. Kubelet generates a private key and uses it to send a PodCertificateRequest to the named signer. Once the signer approves the request and issues a certificate chain, Kubelet writes the key and certificate chain to the pod filesystem. The pod does not start until certificates have been issued for each podCertificate projected volume source in its spec. Kubelet will begin trying to rotate the certificate at the time indicated by the signer using the PodCertificateRequest.Status.BeginRefreshAt timestamp. Kubelet can write a single file, indicated by the credentialBundlePath field, or separate files, indicated by the keyPath and certificateChainPath fields. The credential bundle is a single file in PEM format. The first PEM entry is the private key (in PKCS#8 format), and the remaining PEM entries are the certificate chain issued by the signer (typically, signers will return their certificate chain in leaf-to-root order). Prefer using the credential bundle format, since your application code can read it atomically. If you use keyPath and certificateChainPath, your application must make two separate file reads. If these coincide with a certificate rotation, it is possible that the private key and leaf certificate you read may not correspond to each other. Your application will need to check for this condition, and re-read until they are consistent. The named signer controls chooses the format of the certificate it issues; consult the signer implementation's documentation to learn how to use the certificates it issues. |

Projects an auto-rotating credential bundle (private key and certificate chain) that the pod can use either as a TLS client or server. Kubelet generates a private key and uses it to send a PodCertificateRequest to the named signer. Once the signer approves the request and issues a certificate chain, Kubelet writes the key and certificate chain to the pod filesystem. The pod does not start until certificates have been issued for each podCertificate projected volume source in its spec. Kubelet will begin trying to rotate the certificate at the time indicated by the signer using the PodCertificateRequest.Status.BeginRefreshAt timestamp. Kubelet can write a single file, indicated by the credentialBundlePath field, or separate files, indicated by the keyPath and certificateChainPath fields. The credential bundle is a single file in PEM format. The first PEM entry is the private key (in PKCS#8 format), and the remaining PEM entries are the certificate chain issued by the signer (typically, signers will return their certificate chain in leaf-to-root order). Prefer using the credential bundle format, since your application code can read it atomically. If you use keyPath and certificateChainPath, your application must make two separate file reads. If these coincide with a certificate rotation, it is possible that the private key and leaf certificate you read may not correspond to each other. Your application will need to check for this condition, and re-read until they are consistent. The named signer controls chooses the format of the certificate it issues; consult the signer implementation's documentation to learn how to use the certificates it issues.
| name | type | required | description |
|---|
| certificateChainPath | string | ❌ | Write the certificate chain at this path in the projected volume. Most applications should use credentialBundlePath. When using keyPath and certificateChainPath, your application needs to check that the key and leaf certificate are consistent, because it is possible to read the files mid-rotation. |
| credentialBundlePath | string | ❌ | Write the credential bundle at this path in the projected volume. The credential bundle is a single file that contains multiple PEM blocks. The first PEM block is a PRIVATE KEY block, containing a PKCS#8 private key. The remaining blocks are CERTIFICATE blocks, containing the issued certificate chain from the signer (leaf and any intermediates). Using credentialBundlePath lets your Pod's application code make a single atomic read that retrieves a consistent key and certificate chain. If you project them to separate files, your application code will need to additionally check that the leaf certificate was issued to the key. |
| keyPath | string | ❌ | Write the key at this path in the projected volume. Most applications should use credentialBundlePath. When using keyPath and certificateChainPath, your application needs to check that the key and leaf certificate are consistent, because it is possible to read the files mid-rotation. |
| keyType | string | ✅ | The type of keypair Kubelet will generate for the pod. Valid values are "RSA3072", "RSA4096", "ECDSAP256", "ECDSAP384", "ECDSAP521", and "ED25519". |
| maxExpirationSeconds | integer | ❌ | maxExpirationSeconds is the maximum lifetime permitted for the certificate. Kubelet copies this value verbatim into the PodCertificateRequests it generates for this projection. If omitted, kube-apiserver will set it to 86400(24 hours). kube-apiserver will reject values shorter than 3600 (1 hour). The maximum allowable value is 7862400 (91 days). The signer implementation is then free to issue a certificate with any lifetime shorter than MaxExpirationSeconds, but no shorter than 3600 seconds (1 hour). This constraint is enforced by kube-apiserver. kubernetes.io signers will never issue certificates with a lifetime longer than 24 hours. |

| ports | []object | ❌ | List of ports to expose from the container. Not specifying a port here DOES NOT prevent that port from being exposed. Any port which is listening on the default "0.0.0.0" address inside a container will be accessible from the network. Modifying this array with strategic merge patch may corrupt the data. For more information See https://github.com/kubernetes/kubernetes/issues/108255. Cannot be updated. |
| readinessProbe | object | ❌ | Periodic probe of container service readiness. Container will be removed from service endpoints if the probe fails. Cannot be updated. More info: https://kubernetes.io/docs/concepts/workloads/pods/pod-lifecycle#container-probes |
| resizePolicy | []object | ❌ | Resources resize policy for the container. |
| resources | object | ❌ | Compute Resources required by this container. Cannot be updated. More info: https://kubernetes.io/docs/concepts/configuration/manage-resources-containers/ |
| restartPolicy | string | ❌ | RestartPolicy defines the restart behavior of individual containers in a pod. This overrides the pod-level restart policy. When this field is not specified, the restart behavior is defined by the Pod's restart policy and the container type. Additionally, setting the RestartPolicy as "Always" for the init container will have the following effect: this init container will be continually restarted on exit until all regular containers have terminated. Once all regular containers have completed, all init containers with restartPolicy "Always" will be shut down. This lifecycle differs from normal init containers and is often referred to as a "sidecar" container. Although this init container still starts in the init container sequence, it does not wait for the container to complete before proceeding to the next init container. Instead, the next init container starts immediately after this init container is started, or after any startupProbe has successfully completed. |
| restartPolicyRules | []object | ❌ | Represents a list of rules to be checked to determine if the container should be restarted on exit. The rules are evaluated in order. Once a rule matches a container exit condition, the remaining rules are ignored. If no rule matches the container exit condition, the Container-level restart policy determines the whether the container is restarted or not. Constraints on the rules: - At most 20 rules are allowed. - Rules can have the same action. - Identical rules are not forbidden in validations. When rules are specified, container MUST set RestartPolicy explicitly even it if matches the Pod's RestartPolicy. |
| securityContext | object | ❌ | SecurityContext defines the security options the container should be run with. If set, the fields of SecurityContext override the equivalent fields of PodSecurityContext. More info: https://kubernetes.io/docs/tasks/configure-pod-container/security-context/ |
| startupProbe | object | ❌ | StartupProbe indicates that the Pod has successfully initialized. If specified, no other probes are executed until this completes successfully. If this probe fails, the Pod will be restarted, just as if the livenessProbe failed. This can be used to provide different probe parameters at the beginning of a Pod's lifecycle, when it might take a long time to load data or warm a cache, than during steady-state operation. This cannot be updated. More info: https://kubernetes.io/docs/concepts/workloads/pods/pod-lifecycle#container-probes |
| stdin | boolean | ❌ | Whether this container should allocate a buffer for stdin in the container runtime. If this is not set, reads from stdin in the container will always result in EOF. Default is false. |
| stdinOnce | boolean | ❌ | Whether the container runtime should close the stdin channel after it has been opened by a single attach. When stdin is true the stdin stream will remain open across multiple attach sessions. If stdinOnce is set to true, stdin is opened on container start, is empty until the first client attaches to stdin, and then remains open and accepts data until the client disconnects, at which time stdin is closed and remains closed until the container is restarted. If this flag is false, a container processes that reads from stdin will never receive an EOF. Default is false |
| terminationMessagePath | string | ❌ | Optional: Path at which the file to which the container's termination message will be written is mounted into the container's filesystem. Message written is intended to be brief final status, such as an assertion failure message. Will be truncated by the node if greater than 4096 bytes. The total message length across all containers will be limited to 12kb. Defaults to /dev/termination-log. Cannot be updated. |
| terminationMessagePolicy | string | ❌ | Indicate how the termination message should be populated. File will use the contents of terminationMessagePath to populate the container status message on both success and failure. FallbackToLogsOnError will use the last chunk of container log output if the termination message file is empty and the container exited with an error. The log output is limited to 2048 bytes or 80 lines, whichever is smaller. Defaults to File. Cannot be updated. |
| tty | boolean | ❌ | Whether this container should allocate a TTY for itself, also requires 'stdin' to be true. Default is false. |

Double $$ are reduced to a single $, which allows for escaping the $(VAR_NAME) syntax: i.e. "$$(VAR_NAME)" will produce the string literal "$(VAR_NAME)". Escaped references will never be expanded, regardless of whether the variable exists or not. Defaults to "". |

The grace period is the duration in seconds after the processes running in the pod are sent a termination signal and the time when the processes are forcibly halted with a kill signal. Set this value longer than the expected cleanup time for your process. If this value is nil, the pod's terminationGracePeriodSeconds will be used. Otherwise, this value overrides the value provided by the pod spec. Value must be non-negative integer. The value zero indicates stop immediately via the kill signal (no opportunity to shut down). This is a beta field and requires enabling ProbeTerminationGracePeriod feature gate. Minimum value is 1. spec.terminationGracePeriodSeconds is used if unset. |
| timeoutSeconds | integer | ❌ | Number of seconds after which the probe times out. Defaults to 1 second. Minimum value is 1. More info: https://kubernetes.io/docs/concepts/workloads/pods/pod-lifecycle#container-probes |
Exec specifies a command to execute in the container.
| name | type | required | description |
|---|
| command | []string | ❌ | Command is the command line to execute inside the container, the working directory for the command is root ('/') in the container's filesystem. The command is simply exec'd, it is not run inside a shell, so traditional shell instructions ('|', etc) won't work. To use a shell, you need to explicitly call out to that shell. Exit status of 0 is treated as live/healthy and non-zero is unhealthy. |
GRPC specifies a GRPC HealthCheckRequest.

| mountPath | string | ✅ | Path within the container at which the volume should be mounted. Must not contain ':'. |
| mountPropagation | string | ❌ | mountPropagation determines how mounts are propagated from the host to container and the other way around. When not set, MountPropagationNone is used. This field is beta in 1.10. When RecursiveReadOnly is set to IfPossible or to Enabled, MountPropagation must be None or unspecified (which defaults to None). |
| name | string | ✅ | This must match the Name of a Volume. |
| readOnly | boolean | ❌ | Mounted read-only if true, read-write otherwise (false or unspecified). Defaults to false. |
| recursiveReadOnly | string | ❌ | RecursiveReadOnly specifies whether read-only mounts should be handled recursively. If ReadOnly is false, this field has no meaning and must be unspecified. If ReadOnly is true, and this field is set to Disabled, the mount is not made recursively read-only. If this field is set to IfPossible, the mount is made recursively read-only, if it is supported by the container runtime. If this field is set to Enabled, the mount is made recursively read-only if it is supported by the container runtime, otherwise the pod will not be started and an error will be generated to indicate the reason. If this field is set to IfPossible or Enabled, MountPropagation must be set to None (or be unspecified, which defaults to None). If this field is not specified, it is treated as an equivalent of Disabled. |
| subPath | string | ❌ | Path within the volume from which the container's volume should be mounted. Defaults to "" (volume's root). |
| subPathExpr | string | ❌ | Expanded path within the volume from which the container's volume should be mounted. Behaves similarly to SubPath but environment variable references $(VAR_NAME) are expanded using the container's environment. Defaults to "" (volume's root). SubPathExpr and SubPath are mutually exclusive. |

Tolerations of a PgBouncer pod. Changing this value causes PgBouncer to restart. More info: https://kubernetes.io/docs/concepts/scheduling-eviction/taint-and-toleration
| name | type | required | description |
|---|
| effect | string | ❌ | Effect indicates the taint effect to match. Empty means match all taint effects. When specified, allowed values are NoSchedule, PreferNoSchedule and NoExecute. |
| key | string | ❌ | Key is the taint key that the toleration applies to. Empty means match all taint keys. If the key is empty, operator must be Exists; this combination means to match all values and all keys. |
| operator | string | ❌ | Operator represents a key's relationship to the value. Valid operators are Exists and Equal. Defaults to Equal. Exists is equivalent to wildcard for value, so that a pod can tolerate all taints of a particular category. |
| tolerationSeconds | integer | ❌ | TolerationSeconds represents the period of time the toleration (which must be of effect NoExecute, otherwise this field is ignored) tolerates the taint. By default, it is not set, which means tolerate the taint forever (do not evict). Zero and negative values will be treated as 0 (evict immediately) by the system. |
| value | string | ❌ | Value is the taint value the toleration matches to. If the operator is Exists, the value should be empty, otherwise just a regular string. |
Topology spread constraints of a PgBouncer pod. Changing this value causes PgBouncer to restart. More info: https://kubernetes.io/docs/concepts/workloads/pods/pod-topology-spread-constraints/
| name | type | required | description |
|---|
| labelSelector | object | ❌ | LabelSelector is used to find matching pods. Pods that match this label selector are counted to determine the number of pods in their corresponding topology domain. |
| matchLabelKeys | []string | ❌ | MatchLabelKeys is a set of pod label keys to select the pods over which spreading will be calculated. The keys are used to lookup values from the incoming pod labels, those key-value labels are ANDed with labelSelector to select the group of existing pods over which spreading will be calculated for the incoming pod. The same key is forbidden to exist in both MatchLabelKeys and LabelSelector. MatchLabelKeys cannot be set when LabelSelector isn't set. Keys that don't exist in the incoming pod labels will be ignored. A null or empty list means only match against labelSelector. This is a beta field and requires the MatchLabelKeysInPodTopologySpread feature gate to be enabled (enabled by default). |
| maxSkew | integer | ✅ | MaxSkew describes the degree to which pods may be unevenly distributed. When whenUnsatisfiable=DoNotSchedule, it is the maximum permitted difference between the number of matching pods in the target topology and the global minimum. The global minimum is the minimum number of matching pods in an eligible domain or zero if the number of eligible domains is less than MinDomains. For example, in a 3-zone cluster, MaxSkew is set to 1, and pods with the same labelSelector spread as 2/2/1: In this case, the global minimum is 1. | zone1 | zone2 | zone3 | | P P | P P | P | - if MaxSkew is 1, incoming pod can only be scheduled to zone3 to become 2/2/2; scheduling it onto zone1(zone2) would make the ActualSkew(3-1) on zone1(zone2) violate MaxSkew(1). - if MaxSkew is 2, incoming pod can be scheduled onto any zone. When whenUnsatisfiable=ScheduleAnyway, it is used to give higher precedence to topologies that satisfy it. It's a required field. Default value is 1 and 0 is not allowed. |
| minDomains | integer | ❌ | MinDomains indicates a minimum number of eligible domains. When the number of eligible domains with matching topology keys is less than minDomains, Pod Topology Spread treats "global minimum" as 0, and then the calculation of Skew is performed. And when the number of eligible domains with matching topology keys equals or greater than minDomains, this value has no effect on scheduling. As a result, when the number of eligible domains is less than minDomains, scheduler won't schedule more than maxSkew Pods to those domains. If value is nil, the constraint behaves as if MinDomains is equal to 1. Valid values are integers greater than 0. When value is not nil, WhenUnsatisfiable must be DoNotSchedule. For example, in a 3-zone cluster, MaxSkew is set to 2, MinDomains is set to 5 and pods with the same labelSelector spread as 2/2/2: | zone1 | zone2 | zone3 | | P P | P P | P P | The number of domains is less than 5(MinDomains), so "global minimum" is treated as 0. In this situation, new pod with the same labelSelector cannot be scheduled, because computed skew will be 3(3 - 0) if new Pod is scheduled to any of the three zones, it will violate MaxSkew. |
| nodeAffinityPolicy | string | ❌ | NodeAffinityPolicy indicates how we will treat Pod's nodeAffinity/nodeSelector when calculating pod topology spread skew. Options are: - Honor: only nodes matching nodeAffinity/nodeSelector are included in the calculations. - Ignore: nodeAffinity/nodeSelector are ignored. All nodes are included in the calculations. If this value is nil, the behavior is equivalent to the Honor policy. |
| nodeTaintsPolicy | string | ❌ | NodeTaintsPolicy indicates how we will treat node taints when calculating pod topology spread skew. Options are: - Honor: nodes without taints, along with tainted nodes for which the incoming pod has a toleration, are included. - Ignore: node taints are ignored. All nodes are included. If this value is nil, the behavior is equivalent to the Ignore policy. |
| topologyKey | string | ✅ | TopologyKey is the key of node labels. Nodes that have a label with this key and identical values are considered to be in the same topology. We consider each <key, value> as a "bucket", and try to put balanced number of pods into each bucket. We define a domain as a particular instance of a topology. Also, we define an eligible domain as a domain whose nodes meet the requirements of nodeAffinityPolicy and nodeTaintsPolicy. e.g. If TopologyKey is "kubernetes.io/hostname", each Node is a domain of that topology. And, if TopologyKey is "topology.kubernetes.io/zone", each zone is a domain of that topology. It's a required field. |
| whenUnsatisfiable | string | ✅ | WhenUnsatisfiable indicates how to deal with a pod if it doesn't satisfy the spread constraint. - DoNotSchedule (default) tells the scheduler not to schedule it. - ScheduleAnyway tells the scheduler to schedule the pod in any location, but giving higher precedence to topologies that would help reduce the skew. A constraint is considered "Unsatisfiable" for an incoming pod if and only if every possible node assignment for that pod would violate "MaxSkew" on some topology. For example, in a 3-zone cluster, MaxSkew is set to 1, and pods with the same labelSelector spread as 3/1/1: | zone1 | zone2 | zone3 | | P P P | P | P | If WhenUnsatisfiable is set to DoNotSchedule, incoming pod can only be scheduled to zone2(zone3) to become 3/2/1(3/1/2) as ActualSkew(2-1) on zone2(zone3) satisfies MaxSkew(1). In other words, the cluster can still be imbalanced, but scheduler won't make it more imbalanced. It's a required field. |

IfNotPresent: the kubelet pulls if the reference isn't already present on disk. Container creation will fail if the reference isn't present and the pull fails. Defaults to Always if :latest tag is specified, or IfNotPresent otherwise. |
| reference | string | ✅ | Required: Image or artifact reference to be used. Behaves in the same way as pod.spec.containers[*].image. Pull secrets will be assembled in the same way as for the container image by looking up node credentials, SA image pull secrets, and pod spec image pull secrets.

| podCertificate | object | ❌ | Projects an auto-rotating credential bundle (private key and certificate chain) that the pod can use either as a TLS client or server. Kubelet generates a private key and uses it to send a PodCertificateRequest to the named signer. Once the signer approves the request and issues a certificate chain, Kubelet writes the key and certificate chain to the pod filesystem. The pod does not start until certificates have been issued for each podCertificate projected volume source in its spec. Kubelet will begin trying to rotate the certificate at the time indicated by the signer using the PodCertificateRequest.Status.BeginRefreshAt timestamp. Kubelet can write a single file, indicated by the credentialBundlePath field, or separate files, indicated by the keyPath and certificateChainPath fields. The credential bundle is a single file in PEM format. The first PEM entry is the private key (in PKCS#8 format), and the remaining PEM entries are the certificate chain issued by the signer (typically, signers will return their certificate chain in leaf-to-root order). Prefer using the credential bundle format, since your application code can read it atomically. If you use keyPath and certificateChainPath, your application must make two separate file reads. If these coincide with a certificate rotation, it is possible that the private key and leaf certificate you read may not correspond to each other. Your application will need to check for this condition, and re-read until they are consistent. The named signer controls chooses the format of the certificate it issues; consult the signer implementation's documentation to learn how to use the certificates it issues. |

Projects an auto-rotating credential bundle (private key and certificate chain) that the pod can use either as a TLS client or server. Kubelet generates a private key and uses it to send a PodCertificateRequest to the named signer. Once the signer approves the request and issues a certificate chain, Kubelet writes the key and certificate chain to the pod filesystem. The pod does not start until certificates have been issued for each podCertificate projected volume source in its spec. Kubelet will begin trying to rotate the certificate at the time indicated by the signer using the PodCertificateRequest.Status.BeginRefreshAt timestamp. Kubelet can write a single file, indicated by the credentialBundlePath field, or separate files, indicated by the keyPath and certificateChainPath fields. The credential bundle is a single file in PEM format. The first PEM entry is the private key (in PKCS#8 format), and the remaining PEM entries are the certificate chain issued by the signer (typically, signers will return their certificate chain in leaf-to-root order). Prefer using the credential bundle format, since your application code can read it atomically. If you use keyPath and certificateChainPath, your application must make two separate file reads. If these coincide with a certificate rotation, it is possible that the private key and leaf certificate you read may not correspond to each other. Your application will need to check for this condition, and re-read until they are consistent. The named signer controls chooses the format of the certificate it issues; consult the signer implementation's documentation to learn how to use the certificates it issues.
| name | type | required | description |
|---|
| certificateChainPath | string | ❌ | Write the certificate chain at this path in the projected volume. Most applications should use credentialBundlePath. When using keyPath and certificateChainPath, your application needs to check that the key and leaf certificate are consistent, because it is possible to read the files mid-rotation. |
| credentialBundlePath | string | ❌ | Write the credential bundle at this path in the projected volume. The credential bundle is a single file that contains multiple PEM blocks. The first PEM block is a PRIVATE KEY block, containing a PKCS#8 private key. The remaining blocks are CERTIFICATE blocks, containing the issued certificate chain from the signer (leaf and any intermediates). Using credentialBundlePath lets your Pod's application code make a single atomic read that retrieves a consistent key and certificate chain. If you project them to separate files, your application code will need to additionally check that the leaf certificate was issued to the key. |
| keyPath | string | ❌ | Write the key at this path in the projected volume. Most applications should use credentialBundlePath. When using keyPath and certificateChainPath, your application needs to check that the key and leaf certificate are consistent, because it is possible to read the files mid-rotation. |
| keyType | string | ✅ | The type of keypair Kubelet will generate for the pod. Valid values are "RSA3072", "RSA4096", "ECDSAP256", "ECDSAP384", "ECDSAP521", and "ED25519". |
| maxExpirationSeconds | integer | ❌ | maxExpirationSeconds is the maximum lifetime permitted for the certificate. Kubelet copies this value verbatim into the PodCertificateRequests it generates for this projection. If omitted, kube-apiserver will set it to 86400(24 hours). kube-apiserver will reject values shorter than 3600 (1 hour). The maximum allowable value is 7862400 (91 days). The signer implementation is then free to issue a certificate with any lifetime shorter than MaxExpirationSeconds, but no shorter than 3600 seconds (1 hour). This constraint is enforced by kube-apiserver. kubernetes.io signers will never issue certificates with a lifetime longer than 24 hours. |
| signerName | string | ✅ | Kubelet's generated CSRs will be addressed to this signer. |

| dataSourceRef | object | ❌ | dataSourceRef specifies the object from which to populate the volume with data, if a non-empty volume is desired. This may be any object from a non-empty API group (non core object) or a PersistentVolumeClaim object. When this field is specified, volume binding will only succeed if the type of the specified object matches some installed volume populator or dynamic provisioner. This field will replace the functionality of the dataSource field and as such if both fields are non-empty, they must have the same value. For backwards compatibility, when namespace isn't specified in dataSourceRef, both fields (dataSource and dataSourceRef) will be set to the same value automatically if one of them is empty and the other is non-empty. When namespace is specified in dataSourceRef, dataSource isn't set to the same value and must be empty. There are three important differences between dataSource and dataSourceRef: * While dataSource only allows two specific types of objects, dataSourceRef allows any non-core object, as well as PersistentVolumeClaim objects. * While dataSource ignores disallowed values (dropping them), dataSourceRef preserves all values, and generates an error if a disallowed value is specified. * While dataSource only allows local objects, dataSourceRef allows objects in any namespaces.

If the claim enters an Infeasible error state, this field can be reset to its previous value (including nil) to cancel the modification. If the resource referred to by volumeAttributesClass does not exist, this PersistentVolumeClaim will be set to a Pending state, as reflected by the modifyVolumeStatus field, until such as a resource exists.

| name | type | required | description |
|---|
| effect | string | ❌ | Effect indicates the taint effect to match. Empty means match all taint effects. When specified, allowed values are NoSchedule, PreferNoSchedule and NoExecute. |
| key | string | ❌ | Key is the taint key that the toleration applies to. Empty means match all taint keys. If the key is empty, operator must be Exists; this combination means to match all values and all keys. |
| operator | string | ❌ | Operator represents a key's relationship to the value. Valid operators are Exists and Equal. Defaults to Equal. Exists is equivalent to wildcard for value, so that a pod can tolerate all taints of a particular category. |
| tolerationSeconds | integer | ❌ | TolerationSeconds represents the period of time the toleration (which must be of effect NoExecute, otherwise this field is ignored) tolerates the taint. By default, it is not set, which means tolerate the taint forever (do not evict). Zero and negative values will be treated as 0 (evict immediately) by the system. |

Topology spread constraints of a pgAdmin pod. Changing this value causes pgAdmin to restart. More info: https://kubernetes.io/docs/concepts/workloads/pods/pod-topology-spread-constraints/
| name | type | required | description |
|---|
| labelSelector | object | ❌ | LabelSelector is used to find matching pods. Pods that match this label selector are counted to determine the number of pods in their corresponding topology domain. |
| matchLabelKeys | []string | ❌ | MatchLabelKeys is a set of pod label keys to select the pods over which spreading will be calculated. The keys are used to lookup values from the incoming pod labels, those key-value labels are ANDed with labelSelector to select the group of existing pods over which spreading will be calculated for the incoming pod. The same key is forbidden to exist in both MatchLabelKeys and LabelSelector. MatchLabelKeys cannot be set when LabelSelector isn't set. Keys that don't exist in the incoming pod labels will be ignored. A null or empty list means only match against labelSelector. This is a beta field and requires the MatchLabelKeysInPodTopologySpread feature gate to be enabled (enabled by default). |
| maxSkew | integer | ✅ | MaxSkew describes the degree to which pods may be unevenly distributed. When whenUnsatisfiable=DoNotSchedule, it is the maximum permitted difference between the number of matching pods in the target topology and the global minimum. The global minimum is the minimum number of matching pods in an eligible domain or zero if the number of eligible domains is less than MinDomains. For example, in a 3-zone cluster, MaxSkew is set to 1, and pods with the same labelSelector spread as 2/2/1: In this case, the global minimum is 1. | zone1 | zone2 | zone3 | | P P | P P | P | - if MaxSkew is 1, incoming pod can only be scheduled to zone3 to become 2/2/2; scheduling it onto zone1(zone2) would make the ActualSkew(3-1) on zone1(zone2) violate MaxSkew(1). - if MaxSkew is 2, incoming pod can be scheduled onto any zone. When whenUnsatisfiable=ScheduleAnyway, it is used to give higher precedence to topologies that satisfy it. It's a required field. Default value is 1 and 0 is not allowed. |
| minDomains | integer | ❌ | MinDomains indicates a minimum number of eligible domains. When the number of eligible domains with matching topology keys is less than minDomains, Pod Topology Spread treats "global minimum" as 0, and then the calculation of Skew is performed. And when the number of eligible domains with matching topology keys equals or greater than minDomains, this value has no effect on scheduling. As a result, when the number of eligible domains is less than minDomains, scheduler won't schedule more than maxSkew Pods to those domains. If value is nil, the constraint behaves as if MinDomains is equal to 1. Valid values are integers greater than 0. When value is not nil, WhenUnsatisfiable must be DoNotSchedule. For example, in a 3-zone cluster, MaxSkew is set to 2, MinDomains is set to 5 and pods with the same labelSelector spread as 2/2/2: | zone1 | zone2 | zone3 | | P P | P P | P P | The number of domains is less than 5(MinDomains), so "global minimum" is treated as 0. In this situation, new pod with the same labelSelector cannot be scheduled, because computed skew will be 3(3 - 0) if new Pod is scheduled to any of the three zones, it will violate MaxSkew. |
| nodeAffinityPolicy | string | ❌ | NodeAffinityPolicy indicates how we will treat Pod's nodeAffinity/nodeSelector when calculating pod topology spread skew. Options are: - Honor: only nodes matching nodeAffinity/nodeSelector are included in the calculations. - Ignore: nodeAffinity/nodeSelector are ignored. All nodes are included in the calculations. If this value is nil, the behavior is equivalent to the Honor policy. |
| nodeTaintsPolicy | string | ❌ | NodeTaintsPolicy indicates how we will treat node taints when calculating pod topology spread skew. Options are: - Honor: nodes without taints, along with tainted nodes for which the incoming pod has a toleration, are included. - Ignore: node taints are ignored. All nodes are included. If this value is nil, the behavior is equivalent to the Ignore policy. |
| topologyKey | string | ✅ | TopologyKey is the key of node labels. Nodes that have a label with this key and identical values are considered to be in the same topology. We consider each <key, value> as a "bucket", and try to put balanced number of pods into each bucket. We define a domain as a particular instance of a topology. Also, we define an eligible domain as a domain whose nodes meet the requirements of nodeAffinityPolicy and nodeTaintsPolicy. e.g. If TopologyKey is "kubernetes.io/hostname", each Node is a domain of that topology. And, if TopologyKey is "topology.kubernetes.io/zone", each zone is a domain of that topology. It's a required field. |
| whenUnsatisfiable | string | ✅ | WhenUnsatisfiable indicates how to deal with a pod if it doesn't satisfy the spread constraint. - DoNotSchedule (default) tells the scheduler not to schedule it. - ScheduleAnyway tells the scheduler to schedule the pod in any location, but giving higher precedence to topologies that would help reduce the skew. A constraint is considered "Unsatisfiable" for an incoming pod if and only if every possible node assignment for that pod would violate "MaxSkew" on some topology. For example, in a 3-zone cluster, MaxSkew is set to 1, and pods with the same labelSelector spread as 3/1/1: | zone1 | zone2 | zone3 | | P P P | P | P | If WhenUnsatisfiable is set to DoNotSchedule, incoming pod can only be scheduled to zone2(zone3) to become 3/2/1(3/1/2) as ActualSkew(2-1) on zone2(zone3) satisfies MaxSkew(1). In other words, the cluster can still be imbalanced, but scheduler won't make it more imbalanced. It's a required field. |
LabelSelector is used to find matching pods. Pods that match this label selector are counted to determine the number of pods in their corresponding topology domain.
