- # 'PetSets' were ALPHA resources in Kube <= 3.4. In >= 3.5 they are

- # them. We can't migrate clients PetSets to
- # StatefulSets. Additionally, Red Hat has never officially supported
- # these resource types. Sorry users, but if you were using
- # unsupported resources from the Kube documentation then we can't
- # help you at this time.

- msg: >
- PetSet objects were detected in your cluster. These are an
- Alpha feature in upstream Kubernetes 1.4 and are not supported
- by Red Hat. In Kubernetes 1.5, they are replaced by the Beta
- feature StatefulSets. Red Hat currently does not offer support
- for either PetSets or StatefulSets.
- Automatically migrating PetSets to StatefulSets in OpenShift
- Container Platform (OCP) 3.5 is not supported. See the
- Kubernetes "Upgrading from PetSets to StatefulSets"
- documentation for additional information:
- https://kubernetes.io/docs/tasks/manage-stateful-set/upgrade-pet-set-to-stateful-set/
- PetSets MUST be removed before upgrading to OCP 3.5. Red Hat
- strongly recommends reading the above referenced documentation
- in its entirety before taking any destructive actions.
- If you want to simply remove all PetSets without manually
- migrating to StatefulSets, run this command as a user with
- cluster-admin privileges:
- $ oc get petsets --all-namespaces -o yaml | oc delete -f - --cascade=false
- when:
- # Search did not fail, valid resource type found
- - l_do_petsets_exist.results.returncode == 0
