------------------------------------

             Summary: Add WATCH_NAMESPACES env var to kubernetes operator
                 Key: FLINK-29536
                 URL: https://issues.apache.org/jira/browse/FLINK-29536
             Project: Flink
          Issue Type: Improvement
          Components: Kubernetes Operator
    Affects Versions: kubernetes-operator-1.2.0
            Reporter: Tony Garrard
             Fix For: kubernetes-operator-1.2.0


Provide the ability to set the namespaces watched by the operator using an env 
var. Whilst the additional config can still be used, the presence of the env 
var will take priority.

 

Reasons for issue
 # Operator will take effect of the setting immediately as pod will roll 
(rather than waiting for the config to be refreshed)
 # If the operator is to be olm bundled we will be able to set the target 
namespace using the following 

{{                    env:}}

  {{                      - name: WATCHED_NAMESPACE}}

      {{                        valueFrom:}}

          {{                          fieldRef:}}

             {{                            fieldPath: 
metadata.annotations['olm.targetNamespaces']}}
