Hello Docker geeks :)

If you run a container and attach to that container you would see its stin, stout or stderr outputs. If you press CTRL+C while you're attached to the container the container will get stopped. In order to detach from the container you can use key sequence CTRL+ p + CTRL+q.

One of the reasons that CTRL+C stops the container is that this key combination sends SIGKILL signal to the container. There is a
parameter called --sig-proxy that is true by default which makes CTRL+C to send SIGINT. You can detach from a container and leave it running using the CTRL-p CTRL-q key sequence.

If you set --sig-proxy to false then CTRL+C would not kill the running container:

docker attach YOUR_CONTAINER_ID --sig-proxy=false

NOTE: you can get container id by issuing docker ps command.

#docker #attach #detach #sig_proxy #sequence_key #SIGINT #SIGKILL
