    I tried Nabil Ghodbane's method, but it didn't work. Thanks to billabongrob's answer, I found a way to fix this problem. You can try this Docker config file:

    $ cat /etc/docker/daemon.json
    {
        "log-level":"warn",
        "hosts": ["unix:///var/run/docker.sock","tcp://0.0.0.0:2375"],
        "runtimes": {
            "docker-runc": {
                "path": "/usr/libexec/docker/docker-runc-current"
            }
        },
        "add-runtime": "docker-runc=/usr/libexec/docker/docker-runc-current",
        "default-runtime": "docker-runc"
    }
    

    or use this config in your command line .

    I know that this is a rather old question; however, this occured when I updated from CentOS - Extras docker to Docker's own docker-ce rpm. The service file located at /usr/lib/systemd/system/docker.service had the following lines hardcoded into the ExecStart line:

    --add-runtime docker-runc=/usr/libexec/docker/docker-runc-current \
    --default-runtime=docker-runc \
    --exec-opt native.cgroupdriver=systemd \
    --userland-proxy-path=/usr/libexec/docker/docker-proxy-current \
    

    By default, the docker-ce package does not come with the same set of lines and the file paths are different. After upgrading I added the following and the containers respected my start commands with no data lost as expected:

     --add-runtime docker-runc=/usr/bin/docker-runc \
        --default-runtime=docker-runc \
        --exec-opt native.cgroupdriver=systemd \
        --userland-proxy-path=/usr/bin/docker-proxy
    

    Hope this helps someone else!

    It seems that the docker rpm misses some symbolic link in the end. As it was pointed to me, this issue was raised on:

    https://access.redhat.com/solutions/2876431
    

    and this can be easily fixed by:

    cd /usr/libexec/docker/
    sudo ln -s docker-runc-current docker-runc

    Please try this

    Failure shim error: docker-runc not installed on system

    cd /usr/libexec/docker/
    cp docker-runc-current /usr/bin/docker-runc

    In reference to the top answer, introduce the sym link in /usr/bin to enable it in global path

    sudo ln -s /usr/libexec/docker/docker-runc-current /usr/bin/docker-runc
