Correct way to detach from a container without stopping it
In Docker 1.1.2 (latest), what's the correct way to detach from a container without stopping it?
So for example, if I try:
docker run -i -t foo /bin/bashor
docker attach foo(for already running container)
both of which get me to a terminal in the container, how do I exit the container's terminal without stopping it?
CTR+C both stop the container.
Update: As mentioned in below answers Ctrl+p, Ctrl+q will now turn interactive mode into daemon mode.
Well Ctrl+C (or Ctrl+\) should detach you from the container but it will kill the container because your main process is a bash.
A little lesson about docker. The container is not a real full functional OS. When you run a container the process you launch take the PID 1 and assume init power. So when that process is terminated the daemon stop the container until a new process is launched (via docker start) (More explanation on the matter http://phusion.github.io/baseimage-docker/#intro)
If you want a container that run in detached mode all the time, i suggest you use
docker run -d foo
With an ssh server on the container. (easiest way is to follow the dockerizing openssh tutorial https://docs.docker.com/engine/examples/running_ssh_service/)
Or you can just relaunch your container via
docker start foo
(it will be detached by default)
