Compatibility Requirements
Container Dependencies
The Operator depends on the Crunchy Containers and there are version dependencies between the two projects.
| Operator Release | Container Release |
|---|---|
| 4.0.0 | 2.4.0 |
| 3.5.2 | 2.3.1 |
Features sometimes are added into the underlying Crunchy Containers to support upstream features in the Operator thus dictating a dependency between the two projects at a specific version level.
Operating Systems
The Operator is developed on both Centos 7 and RHEL 7 operating systems. The underlying containers are designed to use either Centos 7 or RHEL 7 as the base container image.
Other Linux variants are possible but are not supported at this time.
Kubernetes Distributions
The Operator is designed and tested on Kubernetes and Openshift Container Platform.
Storage
The Operator is designed to support HostPath, NFS, and Storage Classes for persistence. The Operator does not currently include code specific to a particular storage vendor.
Releases
The Operator is released on a quarterly basis often to coincide with Postgres releases.
There are pre-release and or minor bug fix releases created on an as-needed basis.
