Assigning Common/Specific Metadata#

Distributing common labels and annotations to tenant namespaces via Tenant Custom Resource#

Bill now wants to add labels/annotations to all the namespaces for a tenant. To create those labels/annotations Bill will just add them into commonMetadata.labels/commonMetadata.annotations field in the tenant CR.

kubectl apply -f - << EOF
apiVersion: tenantoperator.stakater.com/v1beta2
kind: Tenant
metadata:
  name: bluesky
spec:
  owners:
    users:
    - anna@aurora.org
    - anthony@aurora.org
  editors:
    users:
    - john@aurora.org
    groups:
    - alpha
  quota: small
  namespaces:
    withTenantPrefix:
      - dev
      - build
      - prod
  commonMetadata:
    labels:
      app.kubernetes.io/managed-by: tenant-operator
      app.kubernetes.io/part-of: tenant-alpha
    annotations:
      openshift.io/node-selector: node-role.kubernetes.io/infra=
EOF

With the above configuration all tenant namespaces will now contain the mentioned labels and annotations.
