Finding help with the Docker command line

Docker commands are well documented, and can be referred to whenever needed. Lots of documentation is available online as well, but it might differ from the documentation for the Docker version you are running.

Getting ready

First, install Docker on your system.

How to do it...

1. On a Linux-based system, you can use the man command to find help, as follows:

    $ man docker

2. Subcommand-specific help can also be found with either of the following commands:

    $ man docker ps
    $ man docker-ps

How it works...

The man command uses the man pages installed by the Docker package to provide help.
