[jira] [Created] (FLINK-27615) Document the minimum supported version of k8s for flink k8s operator
Biao Geng created FLINK-27615:
---------------------------------
Summary: Document the minimum supported version of k8s for flink k8s operator
Key: FLINK-27615
URL: https://issues.apache.org/jira/browse/FLINK-27615
Project: Flink
Issue Type: Improvement
Reporter: Biao Geng
In our webhook, to support {{{}watchNamespaces{}}}, we rely on the {{kubernetes.io/metadata.name}} to filter the validation requests. However, this label will be automatically added to a namespace only since k8s 1.21.1 due to k8s' [release notes|[https://github.com/kubernetes/kubernetes/blob/master/CHANGELOG/CHANGELOG-1.21.md#v1211] . If users run the flink k8s operator on older k8s versions, they have add such label by themselevs to support the feature of namespaceSelector in our webhook.
As a result, if we want to support the feature defaultly, we may need to emphasize that users should use k8s >= v1.21.1 to run the flink k8s operator.
