Container stops upon exit from the terminal

Docker Engine General
1

Hello,

I’m only starting with Docker.

I observed Docker’s behaviour of which I’m not sure whether it is expected.

  1. I start a container in an interactive mode (-i) with a terminal (-t);
  2. I execute docker attach <container_id> ;
  3. I’m in the container’s terminal executing commands;
  4. I type exit to go back to host’s shell;
  5. The container is no longer running.

I’m not sure why would exiting a container’s terminal stop the whole container. I would be grateful for advice on how to be able to exit containers’ terminals without stopping them.

Hi Lukasz,

To exit a container and to leave it running use: CTRL-p CTRL-q

See: https://docs.docker.com/reference/commandline/cli/#attach

Thanks,

Jerry
