Remove Previous Wordpress Containers
======================================

We need to stop the Wordpress project and remove the containers before
we rebuild the project. As you will learn, Docker containers are
disposable when using volumes because the data and configurations reside
outside of the containers. The containers load that data so users can
interact with it.

#. Change to the Wordpress folder using ``cd ~/wordpress-docker``
#. Stop the project using the command ``docker-compose down -v``

   + Using the ``-v`` flag removes the data associated with the container.

#. Remove any stopped containers or containers that you no longer want running.

   + View stopped containers: ``docker ps -a``
   + Remove a stopped container using the CONTAINER ID:
     ``docker rm 1234567890``

#. Clean up any dangling volumes using
   ``docker volume prune``
#. Physically remove any data stored in the volume directory or
   `db_data` using command ``rm -r db_data``
#. The `wordpress-docker` directory should contain `docker-compose.yml` only.
