Docker now provides updates through the yum package manager. Jan 14, 2018 How to install and use Docker on RHEL 7 or CentOS 7 (method 1) The procedure to install Docker is as follows: Open the terminal application or login to the remote box using ssh command: ssh [email protected] Type the following command to install Docker via yum provided by Red Hat: sudo yum install docker. Since the container image name had a ‘-‘ in it, Docker didn’t know what to do with it. So the fix is to update Docker to the latest stable code which happens to be version 1.5.

'Docker containers wrap a piece of software in a complete filesystem that contains everything needed to run: code, runtime, system tools, system libraries – anything that can be installed on a server. This guarantees that the software will always run the same, regardless of its environment.' - docker.com/what-docker
