Hi… regarding ReplicationController vs ReplicaSet …How will ReplicationController deal with pods that are already in running state and have labels… The RC yaml has no selectors…

Hello, @abhiram guvvala
> If specified, the .spec.template.metadata.labels must be equal to the .spec.selector, or it will be rejected by the API. If .spec.selector is unspecified, it will be defaulted to .spec.template.metadata.labels.
