yea this seems a lot like how I do things with Jenkins-x preview environments. Other parts of the stack are pulled in based on the latest version of the respective helm charts.

Dockup is like Jenkins X, but easy to setup for people who do not know Kubernetes or helm charts. Also we have features like single-use pre-seeded DBs and a deployment form for deploying a custom combination of branches, for example, development branches from two different repositories.
