How do you attach and detach from Docker's process?

Question

I can attach to a docker process but Ctrl+c doesn\'t work to detach from it. exit basically halts the process.

What\'s the recomm

Answer 1

To detach from the container you simply hold Ctrl and press P + Q.

To attach to a running container you use:

$ docker container attach "container_name"

Answer 2

If you only need the docker process to go in the background you can use

Ctrl + Z

Be aware that it is not a real detach and it comes with a performance penalty. (You can return it to foreground with the bg command).

Another option is to just close your terminal, if you don't need it any longer.

Answer 3

To detach the tty without exiting the shell, use the escape sequence Ctrl+P followed by Ctrl+Q. More details here.

Additional info from this source:

• docker run -t -i → can be detached with ^P^Qand reattached with docker attach
• docker run -i → cannot be detached with ^P^Q; will disrupt stdin
• docker run → cannot be detached with ^P^Q; can SIGKILL client; can reattach with docker attach

Answer 4

If you just want to make some modification to files or inspect processes, here's one another solution you probably want.

You could run the following command to execute a new process from the existing container:

sudo docker exec -ti [CONTAINER-ID] bash

will start a new process with bash shell, and you could escape from it by Ctrl+C directly, it won't affect the original process.

Answer 5

1. Open a new terminal
2. Find the running container Id docker ps
3. Kill the container docker kill ${containerId}

Answer 6

I'm on a Mac, and for some reason, Ctrl-p Ctrl-q would only work if I also held Shift
