How to Install Latest Docker on RedHat 7 Linux Server


#1

You can install docker in two ways.

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

  1. Execute the following commands.

     sudo yum updaye -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
    

Install Stable Docker Version from Official Repo

  1. Add the docker repo.

     sudo tee /etc/yum.repos.d/docker.repo <<-EOF
     [dockerrepo]
     name=Docker Repository
     baseurl=https://yum.dockerproject.org/repo/main/centos/7
     enabled=1
     gpgcheck=1
     gpgkey=https://yum.dockerproject.org/gpg
     EOF
    
  2. Update and install docker engine.

     sudo yum update -y
     sudo yum install docker-engine
    
  3. Start the Docker service.

     sudo service docker start
    

Now you will have a working Docker installation. Post a comment if you face any issues.
