    # Create a pod containing the PHP-FPM application (my-php-app)
    # and nginx, each mounting the `shared-files` volume to their
    # respective /var/www/html directories.

    name: phpfpm-nginx-example
    spec:
    volumes:
    # Create the shared files volume to be used in both pods
    - name: shared-files
    emptyDir: {}

    # Add the ConfigMap we declared above as a volume for the pod

    - name: shared-files
    mountPath: /var/www/html
    # Important! After this container has started, the PHP files
    # in our Docker image aren't in the shared volume. We need to
    # get them into the shared volume. If we tried to write directly
    # to this volume from our Docker image the files wouldn't appear
    # in the nginx container.
    #
    # So, after the container has started, copy the PHP files from this
    # container's local filesystem (/app -- added via the Docker image)
    # to the shared volume, which is mounted at /var/www/html.
