Version: Operator 2.5.0

Re-grant RBAC privileges to namespaces

OLM-based installations (OperatorHub.io and RedHat OpenShift) have a known issue with upgrading from version 2.4.0 to 2.5.0. This upgrade scenario revokes the RBAC privileges required to run Aerospike clusters in Kubernetes namespaces other than the aerospike namespace.

Re-grant the RBAC privileges for each Kubernetes namespace (except aerospike) which contains Aerospike clusters.

The procedure to re-grant privileges to a Kubernetes namespace ns1 is as follows. Replace ns1 with the name of your namespace.

Create a service account​

kubectl -n ns1 create serviceaccount aerospike-operator-controller-manager

If the service account already exists, ignore the error you receive.

Update the operator's ClusterRoleBinding​

Next, add this service account to the Operator's ClusterRoleBinding. 

kubectl edit clusterrolebindings.rbac.authorization.k8s.io $(kubectl get clusterrolebindings.rbac.authorization.k8s.io  | grep aerospike-kubernetes-operator | grep -v -- "-opera-" | grep -v -- "default-ns" | cut -f 1 -d " ")

This command launches an editor. Append the following lines to the subjects section:

  # A new entry for ns1.
  # Replace ns1 with your namespace
- kind: ServiceAccount
  name: aerospike-operator-controller-manager
  namespace: ns1

Save and ensure that the changes are applied.

Here is a full example of the Operator's ClusterRoleBinding targeting the ns1 namespace.
