> 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.
