Background # While working on my Docker image for webtrees, I ran into a peculiar issue. I had setup automated builds in Docker Hub for every tagged commit in my git repository. At first, I wanted to be able to have multiple tags for each image build, so that each build could be version tagged (like 1.7.15) and have the latest tag applied as well. Using an undocumented feature, I was able to get that to work. However, problems arose once I wanted to also properly label my image. Specifically, I was trying to add the BUILD_DATE and VCS_REF labels. With Docker Hub, this requires you to add your own build hook in order to pass in the needed build arguments. Using an example I found, I added my own build hook to my repository.
