Proposed changes
After upgrading Helm charts to the ones in version 1.5.0 of the Ingress Controller, there was a problem with old rs/pods not being removed correctly.
With this fix, it is possible to use the
controller.nameto make sure the app selector in deployment/daemonset/service is the same and K8s will update them instead of create new ones.Note: If using a
deployment, the old replicaset will still be there after the update, however, it will have 0 pods. The reason behind it is that the Deployment who is the replicaset owner is still alive, although using a new label. It is safe to remove that replicaset as it doesn't have any pods.
