Launch an Ubuntu container, and attach to its shell

We’ve already run this container in the previous video, so the command is used again as a reminder. However, the command is simplified from the previous video.

 docker run -it ubuntu

Launch an Ubuntu container in a ‘detached’ state

The following command will launch an Ubuntu container similar to before, but will launch it in the background:

 docker run -it -d ubuntu

Launch an Ubuntu container, but have it relaunch if stopped

docker run -d -it –restart unless-stopped ubuntu
