    # Since we're using GKE, we'll use a fork of the kubectl step that supports
    # GKE service account authentication. We need to pass some GKE specific configuration
    # to ensure we can authenticate, then point kubectl at the directory containing our
    # Kubernetes configuration.

    # `apply` is a good command to use here, as it'll create Kubernetes entities if they are missing.
