Delete a Volume

1. Use docker ps -a to see all containers, even those that aren't running.
2. Stop the running Ghost container
3. Remove the ghost container. Use docker --help to find the right command.
4. Remove the ghost-vol volume. Use docker volume --help to find the right command.

Now that it's gone, let's see what happens if we try to start the Ghost container back up and attach it to a volume that doesn't exist.

docker run -d -e NODE_ENV=development -e url=http://localhost:3001 -p 3001:2368 -v ghost-vol:/var/lib/ghost ghost

Navigate to http://localhost:3001/ in your browser, and you should see a fresh CMS. That's weird, why no errors?

Run:

docker volume ls

The ghost-vol is back from the dead!?! It turns out the -v ghost-vol:/var/lib/ghost flag binds to a "ghost-vol" volume if it exists, otherwise, it creates it automatically!

So, we now have a fresh installation. Our post that was on the old volume is gone, but this new volume will persist if we don't delete it.

Run and submit the CLI tests.
