--------------------------------------
Assignee: Márton Balassi
> 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
> Assignee: Márton Balassi
> Priority: Critical
>
> 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.
