Docker Commands Reference Guide

Overview

Below, we will cover some of the basic Docker commands that you will find useful when interacting with Docker containers. Many of these commands can be found on the Docker commands homepage and from the Galaxy Docker Github repositoryGitHub is a web-based Git repository hosting service. It offers all of the distributed version control and source code management (SCM) functionality of Git as well as adding its own features.. They are simply reviewed here for convenience.

By DEFAULT, Galaxy containers are volatile, meaning that once they are stopped, all data and uploaded files will be removed. This command can be used to give a running Galaxy container persistent storage

                                            $ docker run -d -p 8080:80 -v /home/user/galaxy_storage/:/export/ chrisd/amrplusplus
