Update a Self-Service Namespace Using kubectl annotate and kubectl label

As a DevOps engineer you can update or delete self-service namespace annotations and labels using the kubectl annotate and kubectl label commands.

Prerequisites

Verify that you have owner permissions on the namespace that you want to update.

Procedure

1. Log in to the Supervisor Cluster.
   kubectl vsphere login --server IP-ADDRESS-SUPERVISOR-CLUSTER --vsphere-username VCENTER-SSO-USERNAME
2. Describe the namespace that you want to update.

   root@localhost [ /tmp ]# kubectl describe ns testns
   Name:         testns
   Labels:       my-label=test-label-2
                 vSphereClusterID=domain-c50
   Annotations:  my-ann: test-ann-2
                 vmware-system-namespace-owner-count: 2
                 vmware-system-resource-pool: resgroup-153
                 vmware-system-resource-pool-cpu-limit: 0.4770
                 vmware-system-resource-pool-memory-limit: 2000Mi
                 vmware-system-self-service-namespace: true
                 vmware-system-vm-folder: group-v154
   Status:       Active

    requests.storage  0     5000Mi
    
    
    Name:                                                                           testns-storagequota
    Resource                                                                        Used  Hard
    --------                                                                        ---   ---

3. Update annotations using the kubectl annotate command.
   For example, kubectl annotate --overwrite ns testns my-ann="test-ann-3"
   To delete an annotation, run the command kubectl annotate --overwrite ns testns my-ann-
4. Update labels using the kubectl label command.
   For example, kubectl label --overwrite ns testns my-label="test-label-3"
   To delete a label, run the command kubectl label --overwrite ns testns my-label-
5. Describe the namespace to see the updates.

   root@localhost [ /tmp ]# kubectl describe ns testns
   Name:         testns
   Labels:       my-label=test-label-3
                 vSphereClusterID=domain-c50
   Annotations:  my-ann: test-ann-3
                 vmware-system-namespace-owner-count: 2
                 vmware-system-resource-pool: resgroup-153
                 vmware-system-resource-pool-cpu-limit: 0.4770
                 vmware-system-resource-pool-memory-limit: 2000Mi
                 vmware-system-self-service-namespace: true
                 vmware-system-vm-folder: group-v154
   Status:       Active
