    If you are looking for a specific container, you can run:

    docker inspect -f '{{.State.Running}}' $container_name
    

    If you want to know if dockerd is running itself on the local machine and you have systemd installed, you can run:

    systemctl show --property ActiveState docker
    

    You can also connect to docker with docker info or docker version and they will error out if the daemon is unavailable.

    Any docker command (except docker -v), like docker ps

    Docker will be the best open platform for developers and sysadmins to build, ship, and run distributed applications.
