5. View your WordPress site

   $ open http://$(docker port wordpress 80)

6. (Optional) Remove your WordPress site.

   If you aren't going to use your WordPress site, we recommend that you remove it. Doing so removes both your WordPress and MySQL containers. This will delete any data and any posts you've made in the WordPress site.

   $ docker rm --force --volumes wordpress mysql
   wordpress
   mysql

7. Run source ~/cleanup.env
