Stopping Docker Containers from Being there on Startup

Question

Whenever I start Docker on my Mac, there are four containers that come along for the ride and start up automatically.

$ docker ps

    Cannot connect to the Docker daemon at unix:///var/run/docker.sock. Is the docker daemon running?

//starts docker, makes tea    

$ docker ps

How do I tell (Docker? The containers?) that I don't need these four containers to start up automatically anymore?

Answer 1

Check the restart policy of those containers using docker inspect NAME|ID. If it is always or on-failure, then you have the explanation.

To change the restart policy, use docker update --restart <new policy>.

These two commands set the restart policy to no for all running containers and then kill them all (make sure you understand this before doing it):

docker update `docker ps -q` --restart no
docker kill `docker ps -q`

After that, restart your docker daemon and you should see nothing from docker ps.
