Add ssh user to docker group?

[ahmetb]

When I create a machine on Ubuntu, the default ssh user is not added to the docker group (usermod -a -G docker <ssh-user>) and therefore when I do docker-machine ssh vm and type docker ps it doesn't work.

Is it a deliberate decision or just something not implemented? I think fixing this would help making the user experience better.

repro:

~ docker-machine create -d google  --google-project <project> dev
~ docker-machine ssh dev

...in ssh prompt :
docker-user@dev2:~$ docker ps
Cannot connect to the Docker daemon. Is the docker daemon running on this host?

docker-user@dev2:~$ sudo docker ps
(works)

It's always been that way (cfr. amazonec2) but maybe we should add the user automatically for consistency. Historically I have actually been in favor of using sudo with docker (at least in higher environments) but I have to wonder if maybe that ship has sailed and we should just enforce some consistent behavior.

I bet people would be happier if you just add the user to the docker group. That's what curl get.docker.com | sh tells you to do (optionally) anyway, so it's not a bad thing. I also bet, having to type sudo all the time is annoying for most people. :)

Closing as it is by design.
