Biao Geng updated FLINK-27615:
------------------------------
Description:
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 to 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.
Due to aitozi's advice, it may be better to add document of how to support the
nameSelector based validation instead of limiting the k8s version to be >=
1.21.1 to support more users.
