Apply Governance Labels to a Namespace

Apply Governance Labels to a Namespace

Apply a set of governance labels and annotations to an existing namespace.

1. Read the namespace to confirm it exists, capture the labels already in place, and take the resourceVersion for an optimistic-concurrency replace.
2. Replace the namespace with the governance labels applied. The resourceVersion from the read makes the API server reject this write if another client changed the namespace in the meantime.
3. Read the namespace back to confirm the governance labels persisted and that the namespace remains Active rather than Terminating.

What you'll need to have ready

• namespace: The namespace to label.
• labels: Governance labels to apply, such as pod-security.kubernetes.io/enforce, team, or cost-center.
• annotations: Annotations to apply alongside the labels, such as an owner contact.
