Docker pull then start for running container - what is the expected behavior?

  • 772

Let's say I have a running Docker container X that is based on image foo.

If I pull a new version of foo, then stop and delete X, and then docker run foo - will it start the new version of the image?

Said differently - do I need to stop X before I can pull the new version of foo and then start it?

Context: Docker-EE on Windows Server 2016

    You can pull the new version of the image without stopping the original. Docker does not see them as the same image as their layer hashes will differ.
