Products for continuous integration and continuous delivery have become a commodity. But among them is a growing number isolating build steps in containers. Instead of using a fully integrated product, I have created a tool called

Everyone is trying really hard to separate functionality in their Docker images. But we all have one or more images which contain multiple tools and take quiet some time to build. Unfortunately a rebuild will be necessary whenever a small change was made to the
