[jira] [Created] (FLINK-27956) Kubernetes Operator Deployment strategy type should be Recreate

Gyula Fora created FLINK-27956:
----------------------------------

             Summary: Kubernetes Operator Deployment strategy type should be Recreate
                 Key: FLINK-27956
                 URL: https://issues.apache.org/jira/browse/FLINK-27956
             Project: Flink
          Issue Type: Bug
          Components: Kubernetes Operator
    Affects Versions: kubernetes-operator-1.0.0
            Reporter: Gyula Fora


We should change the Deployment strategy.type from the default (RollingUpdate) to Recreate to avoid potential problems when a new operator pod is deployed during upgrade.

[https://kubernetes.io/docs/concepts/workloads/controllers/deployment/#strategy]

 

Only one operator pod is supposed to run at any given time to avoid any errors/inconsistencies, and without HA/leader election, this setting is necessary.
