1.  Install required packages. `yum-utils` provides the `yum-config-manager` utility, and `device-mapper-persistent-data` and `lvm2` are required by the `devicemapper` storage driver.
    
        $ sudo yum install -y yum-utils \ device-mapper-persistent-data \ lvm2
2.  Use the following command to set up the stable repository.
    
        $ sudo yum-config-manager \ --add-repo \ https://download.docker.com/linux/centos/docker-ce.repo

> Optional: Enable the nightly or test repositories.
> 
> These repositories are included in the `docker.repo` file above but are disabled by default. You can enable them alongside the stable repository. The following command enables the nightly repository.
> 
>     $ sudo yum-config-manager --enable docker-ce-nightly
> 
> To enable the test channel, run the following command:
> 
>     $ sudo yum-config-manager --enable docker-ce-test
> 
> You can disable the nightly or test repository by running the `yum-config-manager` command with the `--disable` flag. To re-enable it, use the `--enable` flag. The following command disables the nightly repository.
> 
>     $ sudo yum-config-manager --disable docker-ce-nightly

#### INSTALL DOCKER CE ####

1.  Install the *latest version* of Docker CE and containerd, or go to the next step to install a specific version:
    
        $ sudo yum install docker-ce docker-ce-cli containerd.io Let's get started by modifying systemd's docker start up script. Open file /lib/systemd/system/docker.service with your favorite text editor and replace the following line where /new/path/docker is a location of your new chosen docker directory:
    
        FROM:
        ExecStart=/usr/bin/docker daemon -H fd://
        TO:
        ExecStart=/usr/bin/docker daemon -g /new/path/docker -H fd://
    
        When ready stop docker service:
    
        # systemctl stop docker

        It is important here that you have completely stopped docker daemon. The following linux commandwill yield no output only if docker service is stopped:
    
        # ps aux | grep -i docker | grep -v grep
    
        If no output has been produced by the above command, reload systemd daemon:
    
        # systemctl daemon-reload
    
        Once this is done create a new directory you specified above and optionally rsync current docker data to a new directory:
    
        # mkdir /new/path/docker
        # rsync -aqxP /var/lib/docker/ /new/path/docker
