Install MCR

  1. Install the latest version of MCR and containerd:

    sudo yum -y install docker-ee docker-ee-cli containerd.io
    

    If prompted to accept the GPG key, verify that the fingerprint matches 77FE DA13 1A83 1D29 A418 D3E8 99E5 FF2E 7668 2BC9 and accept it.

    Note

    To install a specific version of MCR:

    sudo yum -y install docker-ee-<version-string> \
    docker-ee-cli-<version-string> containerd.io
    
  2. Start Docker:

    sudo systemctl start docker
    
  3. Verify that you installed MCR correctly:

    sudo docker run hello-world
    

    This command downloads a test image and runs it in a container. If successful, it prints the following informational message and exits:

    Hello from Docker!
    This message shows that your installation appears to be working correctly.
    
    To generate this message, Docker took the following steps:
     1. The Docker client contacted the Docker daemon.
     2. The Docker daemon pulled the "hello-world" image from the Docker Hub.
        (amd64)
     3. The Docker daemon created a new container from that image which runs the
        executable that produces the output you are currently reading.
     4. The Docker daemon streamed that output to the Docker client, which sent it
        to your terminal.
    
    To try something more ambitious, you can run an Ubuntu container with:
     $ docker run -it ubuntu bash
