You can install docker in two ways.

####Install the latest docker community edition using script

  1. Execute the following commands.

     sudo yum update -y
 sudo yum install wget -y
 sudo wget https://download.docker.com/linux/centos/docker-ce.repo -O /etc/yum.repos.d/docker-ce.repo
 sudo yum install -y --setopt=obsoletes=0  docker-ce-17.03.1.ce-1.el7.centos docker-ce-selinux 17.03.1.ce-1.el7.centos

  2. Add your Linux user to docker group to execute docker commands without sudo.

      sudo usermod -aG docker <user-name>

    For example,

     sudo usermod -aG docker michael

    You should restart your terminal for running docker commands without sudo

  3. Start the Docker service, check the status and add docker service to boot.

     sudo service docker start
 sudo service docker status
 sudo chkconfig docker on

 baseurl=https://yum.dockerproject.org/repo/main/centos/7
