Configuring RBAC
To use Stash in a RBAC enabled cluster, install Stash with RBAC options. This creates a ClusterRole named stash-sidecar.
Sidecar container added to workloads makes various calls to Kubernetes api. ServiceAccounts used with Deployment, ReplicaSet, DaemonSet and ReplicationController workloads are automatically bound to stash-sidecar ClusterRole by Stash operator. Users should manually add the following RoleBinding to service accounts used with StatefulSet workloads to authorize these api calls.
apiVersion: rbac.authorization.k8s.io/v1
kind: RoleBinding
metadata:
name: <statefulset-name>-stash-sidecar
namespace: <statefulset-namespace>
roleRef:
apiGroup: rbac.authorization.k8s.io
kind: ClusterRole
name: stash-sidecar
subjects:
- kind: ServiceAccount
name: <statefulset-sa>
namespace: <statefulset-namespace>
