Assigning metadata

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.

Distributing specific labels and annotations to tenant namespaces via Tenant Custom Resource

Bill now wants to add labels/annotations to specific namespaces for a tenant. To create those labels/annotations Bill will just add them into specificMetadata.labels/specificMetadata.annotations and specific namespaces in specificMetadata.namespaces 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
  sandboxConfig:
    enabled: true
  namespaces:
    withTenantPrefix:
      - dev
      - build
      - prod
  specificMetadata:
    - namespaces:
        - bluesky-anna-aurora-sandbox
      labels:
        app.kubernetes.io/is-sandbox: true
      annotations:
        openshift.io/node-selector: node-role.kubernetes.io/worker=
EOF

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

Assigning metadata to all sandboxes

Bill can choose to apply metadata to sandbox namespaces only by using sandboxMetadata property of Tenant CR like below:

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
  sandboxConfig:
    enabled: true
    private: true
  sandboxMetadata: # metadata for all sandbox namespaces
    labels:
      app.kubernetes.io/part-of: che.eclipse.org
    annotations:
      che.eclipse.org/username: "{{ TENANT.USERNAME }}" # templated placeholder

We are using a templated annotation here. See more on supported templated values for labels and annotations for specific MTO CRs here
