Re-grant RBAC privileges to namespaces

There is a known issue with upgrading from version 2.5.0 to 3.0.0. This upgrade scenario revokes the RBAC privileges required to run Aerospike clusters.

Re-grant the RBAC privileges for each Kubernetes namespace 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.

Create RoleBinding/ClusterRoleBinding for Aerospike cluster

Next, create a RoleBinding or ClusterRoleBinding as per requirement to attach this service account to ClusterRole aerospike-cluster. This ClusterRole is created as part of Operator installation.

• For using Kubernetes native Pod only network to connect to Aerospike cluster create RoleBinding:

kubectl -n ns1 create rolebinding aerospike-cluster --clusterrole=aerospike-cluster --serviceaccount=ns1:aerospike-operator-controller-manager

• For connecting to Aerospike cluster from outside Kubernetes create ClusterRoleBinding:

kubectl create clusterrolebinding aerospike-cluster --clusterrole=aerospike-cluster --serviceaccount=ns1:aerospike-operator-controller-manager

tip

For attaching multiple service accounts of different namespaces in one go, add multiple --serviceaccount params in above command

Example: To attach service accounts of ns1 and ns2 namespace

kubectl create clusterrolebinding aerospike-cluster --clusterrole=aerospike-cluster --serviceaccount=ns1:aerospike-operator-controller-manager --serviceaccount=ns2:aerospike-operator-controller-manager

If the required ClusterRoleBinding already exists in cluster, edit it to attach new service account:

kubectl edit clusterrolebinding aerospike-cluster

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
