Help Command

Like most CLI applications, Docker has a built-in help menu. If you ever forget a command or need to see the available options, you can use either of these commands:

docker --help
docker help

Running this will output a comprehensive help menu. There are many commands, but typically you only need to focus on the most common ones like run, ps, stop, rm, images, pull, and exec.

If you need help with a specific command, you can append --help to it. For example, to see the description and options for the build command:

docker build --help
