Docker intro brownbag

The general flow of things is:

• Images
• Containers
• Persistence
• Volumes
• Binds
• Dockerfile intro
• Dockerfile add file
• Dockerfile run file
• Dockerfile simple php server
• Dockerfile configurable php server

Something is broken!

If at any point something is broken and you're not sure what to do, you can run the 'cleanup.sh' script in the root of the repository.

The cleanup script will remove all containers and images build by any shell scripts run in this repo and should get you back to a clean state. You can then start fresh.
