How to display the docker current configuration?

I have installed the docker daemon on a Debian 8 machine. And after setting a value for “DOCKER_OPTS” within the file “/etc/default/docker” I wanted to check if
after restarting the service the value was set properly.

Is there a command to display the current docker’s configuration ?

    After some researches I found the following issue https://github.com/docker/docker/issues/9889 which explains that systemd ignores the configuration file /etc/default/docker. Therefore in my case “DOCKER_OPTS” is not set.

    After editing the file /lib/systemd/system/docker.service it is possible to check that the value is set correctly with the command, mentioned by Adrian, ps aux | grep docker.

    The other useful commands to check the installation version and system information are docker version and docker info.

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