- Add docker.io/library/ prefix to mysql and postgres backup images
to satisfy Kyverno require-trusted-registries policy (both CronJobs
were blocked for 46h, triggering MySQLBackupStale alert)
- Document mysql-operator chart ignoring resources values key — the
LimitRange default (256Mi) was silently applied, putting the operator
at 97% memory. Patched live to 512Mi via kubectl.
- Increase vault-raft-backup backoff_limit to 6 for transient failures
(also fixed NFS export: vault-backup was a separate ZFS dataset not
in the TrueNAS NFS share — destroyed dataset, created directory)
