Create a Self-Service Namespace with Annotations and Labels

DevOps engineers can create self-service namespaces with annotations and labels using the kubectl command line.

DevOps engineers can use a YAML manifest with user-defined annotations and labels.

Procedure

Log in to the Supervisor Cluster.
kubectl vsphere login --server IP-ADDRESS-SUPERVISOR-CLUSTER --vsphere-username VCENTER-SSO-USERNAME

Create a namespace YAML manifest file with annotations and labels.

kubectl create -f ns-create.yaml

For example, create the following ns-create.yaml file:

apiVersion: v1
kind: Namespace
metadata:
  name: test-ns-yaml
  labels:
    my-label: "my-label-val-yaml"
  annotations:
    my-ann-yaml: "my-ann-val-yaml"

Apply the YAML manifest.
kubectl create -f ns-create.yaml
Or
kubectl apply -f ns-create.yaml

Describe the namespace that you created to see the changes.

root@localhost [ /tmp ]# kubectl describe ns test-ns-yaml
Name:         test-ns-yaml
Labels:       my-label=my-label-val-yaml
