The cephrgw-operator reads its Ceph dashboard credentials from Vault via VSO
and needs a Kubernetes auth role bound to its ServiceAccount plus a policy
granting read on the KV path.
- Add config/auth_kubernetes_role/k8s/au/syd1/cephrgw-operator.yaml binding
ServiceAccount cephrgw-operator in namespace cephrgw-system (audience vault).
- Add policies/kv/service/cephrgw/dashboard-credentials/read.yaml granting
read on kv/data/service/cephrgw/dashboard-credentials to that role via the
k8s/au/syd1 auth mount.
