+### StatefulSet pods still get `401 Unauthorized` / `ImagePullBackOff` after enabling registry auth
+
+If `db-0` / `rabbitmq-0` were created **before** `imagePullSecrets` existed, their **Pod** spec can still use anonymous pulls until they are recreated:
+
+```bash
+kubectl delete pod -n onelab db-0 rabbitmq-0
+```
+
+The chart adds a pod-template checksum so a `helm upgrade` after changing registry credentials normally rolls these pods; a one-time delete is enough if you toggled pull secrets outside that path.
