One of the things that gives me pause when looking at images on Docker Hub is that number of Docker images that aren’t open source. It is critical that I see the Dockerfile before loading something up on my machine.
For most of these, it is not difficult to find the associated github repo. It is even better to set up an automated build process, so when code is pushed to the github repo, Docker hub kicks off an image build. I have set up all of my Docker hub entries with this automation.
