✍: FYIcenter.com
If have attached your console to the TTY terminal of the running command
of a container using the "docker container attach" or "docker container start --attach"
command, you can enter the "Ctrl-p Ctrl-q" sequence to detach the console.
After all consoles detached, the container's default command will continuer to run quietly in the Docker Engine.
1. Create a new container with a TTY terminal in interactive mode:
fyicenter$ docker container create --name java --tty --interactive openjdk
2. Start the container with the console attached to the TTY terminal and interact with the default command.
fyicenter$ docker container start --attach --interactive java jshell> 1+2; fyicenter$1 ==> 3
3. Enter "Ctrl-p" followed by "Ctrl-q", you see the console is detached:
jshell> read escape sequence fyicenter$
4. You can attach the console back to the container again:
jshell>5 5+6; fyicenter$5 ==> 11
As you can see, we are able attach and detach a console to the TTY terminal of the default running command on the container at any time.
