Running the Examples
The Kubernetes and OpenShift examples in this guide have been designed using single-node Kubernetes/OCP clusters whose host machines provide any required supporting infrastructure or services (e.g. local HostPath storage or access to an NFS share). Therefore, for the best results when running these examples, it is recommended that you utilize a single-node architecture as well.
Additionally, the examples located in the kube directory work on both Kubernetes and OpenShift.
Please ensure the
CCP_CLI environment variable is set to the correct binary for your environment,
as shown below:
NOTE: Set the
CCP_CLI environment variable in
.bashrc to ensure the examples will work
properly in your environment
The examples provided in Crunchy Container Suite are simple examples that are meant to demonstrate key Crunchy Container Suite features. These examples can be used to build more production level deployments as dictated by user requirements specific to their operating environments.
The examples generally follow these conventions:
- There is a run.sh script that you will execute to start the example
- There is a cleanup.sh script that you will execute to shutdown and cleanup the example
- Each example will create resources such as Secrets, ConfigMaps, Services, and
PersistentVolumeClaims, all which follow a naming convention of
<example name>-<optional description suffix>. For example, an example called primary might
have a PersistentVolumeClaim called primary-pgconf to describe the purpose of that particular
- The folder names for each example give a clue as to which Container Suite feature it
demonstrates. For instance, the
examples/kube/pgaudit example demonstrates how to enable the
pg_audit capability in the crunchy-postgres container.
Here are some useful resources for finding the right commands to troubleshoot and modify containers in the various environments shown in this guide:
Now that your environment has been properly configured for the Crunchy Container Suite and you have reviewed the guidance for running the examples, you are ready to run the Crunchy Container Suite examples. Therefore, please proceed to the next section in order to find the examples that can now be run in your environment.
