--------------------------------------
Summary: Document operator's FlinkVersion compatibility
Key: FLINK-36744
URL: https://issues.apache.org/jira/browse/FLINK-36744
Project: Flink
Issue Type: Improvement
Components: Kubernetes Operator
Affects Versions: kubernetes-operator-1.10.0
Reporter: Dylan Meissner
Starting with Flink Kubernetes Operator 1.7, the operator supports {_}only the
last 4 Flink minor versions corresponding to the date of the operator
release{_}.
This compatibility notice is hard to discovery, and the mapping of versions to
release dates is challenging for casual users and even platform teams to
perform.
The deprecation information does exist in source code:
[https://github.com/apache/flink-kubernetes-operator/blob/release-1.10/flink-kubernetes-operator-api/src/main/java/org/apache/flink/kubernetes/operator/api/spec/FlinkVersion.java#L25]
However, for best usability we should publish the last-four-versions policy and
a history of versions in the operator's *Compatibility Guarantees*
documentation:
[https://nightlies.apache.org/flink/flink-kubernetes-operator-docs-main/docs/operations/compatibility/]
