Install MCR

1. Run the following command to install the latest verison of MCR from the repository:

   $ sudo dnf install docker-ee
   

   If you are prompted to accept the GPG key, first verify that the key has the fingerprint 77FE DA13 1A83 1D29 A418 D3E8 99E5 FF2E 7668 2BC9.

2. Start Docker:

   $ sudo systemctl start docker.service
   

3. Run the hello-world image to verify that MCR is correctly installed. This command downloads a test image, runs it in a container, prints an informational message, and exits:

   $ sudo docker run hello-world
   

   Expected output:

   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
