image-builder
Used to build multiple small docker images from a single git repository. The tool will clone the repo in memory and then calculate which images have change in the latest commit and then build those images before pushing them. The tool requires a certain directory structure to work e.g.
./
hub.docker.com/
hub.docker.com/namespace/
my.private.repo.com/
my.private.repo.com/namespace1/
my.private.repo.com/namespace2/
It will create tags based on the commit hash of HEAD and the current branch name. For example if you had a Jenkins job which always built from the release branch you would end up with a tag called release which always has the latest code and also a tag like abc0123 which refers to the current commit.
