Having difficulties to attach an up state container?

Question

I have created a docker container which is up and running in the background. I tried to attach the container in my terminal using the container id. It enters the container but I can't do anything in it. So, I have to exit every time using ctrl+c.

If the comment by Lawrence Cherone did not help you consider the following options:

1. If you want to invoke a command in a already running container, use docker exec. You can exec into you container by it's name or id. This means you can run a command in a running container. See docs.docker.com: docker exec.

   Example:
   The docker exec command runs the command bash in a running container.

   docker exec -it <container-id> bash
   

   Note: This will really invoke a new command and do not attach to the currelty running command.

2. If you just want to get the putput of a container, you can use docker logs. Again you use your container name or id. See docs.docker.com: docker logs

   Example:

   docker logs <container-id>
