Join Arthur Ulfeldt for an in-depth discussion in this video The Docker flow: Containers to images, part of Learning Docker.
- [Instructor] So we can see we went from an Image…to a Running Container.…When we ran that container again,…we got the same thing we got the first time.…And that's the whole point of images,…it's they are fixed points where you know…everything's good and you can always start from there.…Now when you've got a Running Container,…you make changes to that container, you put files there,…it's very useful, when you want to be able…to actually save those.…The next step in the Docker flow is a Stopped Container.…So the container that's running is alive,…it has a process in it.…
When that process exits, the container is still there,…so that file I created a moment ago,…when I exited that container, it's still there,…I can go back and find it, it didn't get deleted,…it's just that it's currently in a Stopped Container.…So I can look at the most recently exited container…with the docker ps command,…just like I do when I want to look…at the Running Containers, except Stopped Containers…don't show up by default.…
To see Stopped Containers, I can specify the -a argument…
