Configure the Docker Daemon and Install the Docker Client

The Docker daemon is a service that runs on your host operating system. The Docker client is used to issue commands and communicate with the daemon.

The Docker client can reside on the same host as the daemon.

Procedure

1. Configure the Docker daemon in a file, daemon.json, for example:

   vi /etc/docker/daemon.json
   {
   "graph":"/data/mydocker"
   }

2. Run the following commands to install and enable Docker:

   yum install -y wget
   wget -qO- https://get.docker.com | sh
   systemctl start docker
   systemctl enable docker
   service firewalld stop
