The galera controller creates StatefulSet for the db to run. This adds a StatefulSet pod's label "controller-revision-hash": "<statefulset_name>-<hash>" to the pod. The kubernetes label is restricted under 63 char and the revision hash is an int32, 10 chars + the hyphen. The galera controller also adds a suffix '-galera' to the statefulset name. With this the max name must not exceed 46 chars. Depends-On: openstack-k8s-operators/lib-common#562 Jira: https://issues.redhat.com/browse/OSPRH-8063 Signed-off-by: Martin Schuppert <[email protected]> (cherry picked from commit 4f04456)
