How to list all currently running docker containers?

To list all currently running docker containers run

docker ps

If no containers are running, this will give you this output:

CONTAINER ID        IMAGE               COMMAND             CREATED             STATUS              PORTS               NAMES

In case some containers are running, there will be additional lines listing the container like

CONTAINER ID        IMAGE                    COMMAND                  CREATED             STATUS              PORTS                    NAMES
