in this case is exited. You also see any ports or names
that were assigned to the container.
Note
The older syntax for Docker used the ps command
instead of ls (for example, docker ps -a). You can still
type docker container ps -a and get exactly the

container image (ubuntu) in interactive mode and
connects the local terminal to the containers terminal
and launches the bash shell (bash). (The options -i and -
t can be presented separately or together, as -it.)

It executes a Dockerfile hosted on the repository and

Once it is pulled down, the container is started, and the
bash shell is executed. The terminal now shows that you
