For internal k8s config at our org we built an config DSL using Starlark. The golang Starlark interpreter is super easy to use and extend. Starlark is familiar to every developer in our org because we are a Python shop. The tooling then spits out k8s YAML.

Essentially the config language implementation would be the same logic that a helm chart would do, but you’re writing the logic in Go versus a text templating engine. You can easily unit test parts and rely on the compiler to catch basic mistakes. Way better than templating YAML.

We also provide escape hatches so people can easily patch the resources before they get serialized to YAML. People can use that to customize our standard deployment config however they want.

So far this has worked very well and been extremely easy to maintain.
