We started with some pretty cool Jsonnet-based build infrastructure and we're pretty happy with it. Grafana Tanka is also okay, there's tooling to generate Jsonnet libraries for anything that has a CRD. There's jsonnet-bundler for package management. One can throw Flux and Git* actions or what not in the mix. The outcome is a boring CI/CD implementation. Boring is good. Boring and powerful because of how Jsonnet works. It's pretty neat in the right hands.
