- Now users can get object info like:

  ```bash
    a. kubectl get pod test-pod -o custom-columns=CONTAINER:.spec.containers[0:3].name
    b. kubectl get pod test-pod -o custom-columns=CONTAINER:.spec.containers[-2:].name
  ```

- kube-dns add-on:
  - All containers are now being executed under more restrictive privileges.
  - Most of the containers now run as non-root user and has the root filesystem set as read-only.
  - The remaining container running as root only has the minimum Linux capabilities it requires to run.
