Here are some notes about working with Docker. On my Raspberry Pi I need to run all commands as sudo.

First of all, do not confuse the different terms. An image is like a blueprint that serves to generate containers. The containers are then the actual instance that you can start or stop.

List images

docker images

List containers

• Show the running containers:

docker ps

• Show all containers:

docker ps -a

• Use the container command. I don’t know it it differs from the ps command above. The output seems to be the same.

docker container ls

Start a container

• List the available containers (see above)
• Get the container ID to start
• Run

docker start [Container ID]

e.g.

docker start 725dc751823b

Exit a container without stopping it

If started a container with the docker run options -i and -t, you can detach from it and leave it running:

• Press [Ctrl] + [p] followed by [Ctrl] + [q]

Connect/attach to a running container

docker attach [Container ID]
