# Initialize MySQL database.
# ADD this file into the container via Dockerfile.
# Assuming you specify a VOLUME ["/var/lib/mysql"] or `-v /var/lib/mysql` on the `docker run` command…
# Once built, do e.g. `docker run your_image /path/to/docker-mysql-initialize.sh`
# Again, make sure MySQL is persisting data outside the container for this to have any effect.

1. Delete all containers

    $ docker ps -q -a | xargs docker rm
   

-q prints only the container IDs -a prints all containers

Notice that it uses xargs to issue a remove container command for each container ID

2. Delete all untagged images
