Docker ps

docker ps list containers on your system.
A simple docker ps will only list all running containers, whereas for example a docker ps -a will list you all containers (including exited).
It will provide you with crucial informations regarding your containers like the CONTAINER ID, which is especially useful for accessing your container(s).
