If you want to start this container back up you can do so with docker start -ai. If you want to interact with your containers you'll need to know the name or id. Two important fields are CONTAINER ID and NAMES. Take a look at the fields displayed by docker ps -a. Since the containers are designed to run a single process, once that process is finished the container stops. But if you run docker ps -a you'll see all containers including the one you just stopped. You should find that there are no running containers. Now you can run docker ps to see which containers are currently running.

You can run ps to see which processes are running in this ps This is why we've added the options -it to the run command.ДЄfter running this command you should see something like is the bash shell running inside of the container you just created from the ubuntu image. Since we are running a bash shell we are going to want to allocate a pseudo-TTY and keep STDIN open. So we've specified the command to run as /bin/bash. In our case, we are going to run a bash shell. So the docker run command lets you specify a single command to run inside of the container. This is the ubuntu image with the 14.04 tag.Д®ach Docker container should run a single process. In this case, you are creating a container from the ubuntu:14.04 image. The docker run command lets you start a container from an image. Let's take a look at what this command does. Open Terminal (or Docker QuickStart Terminal).
