On Ubuntu, I use Docker intermittently for software development involving packages not currently available through official channels. I'm on a low-spec system and I want to make Docker disappear from the task list when I'm done with it, including all containers, daemons, and Docker-related processes.

I am not running as root, I do not understand systemd, and I have had no luck with killall, docker stop, or docker kill. I don't want Docker starting again, I want it gone until the next time I ask for it. Is there a way to do this?

Stop all containers:

docker stop $(docker ps -q)

Stop docker engine

[sudo] systemctl stop docker

Prevent the engine from being started on reboot:

[sudo] systemctl disable docker

This said, dockerd and docker-containerd are fairly small processes (systemctl status docker reports 65MB total)
