cpswan/testver repository overview

⁠testver

What happens when I update something on Docker Hub?

This is a trivial Dockerfile to test out the linkage between a local registry and Docker Hub.

sudo docker run -it cpswan/testver will pull down the :latest version from Docker Hub when it is first run.

Next time I run sudo docker run -it cpswan/testver (or even cpswan/testver:latest) docker will look in my local registry and find the image there.

If Docker Hub has been updated with a newer version then I have to explicitly sudo docker pull cpswan/testver in order to get it.
