Docker Commands Diagram

We already know how to get a image and modify it, then share it through Docker Hub. It can be more portable and easy to customize. Just write a script in Dockerfile, and then use docker build to build an image following the script in Dockerfile!

Usage: [sudo] docker [command] [flags] [arguments] ..
