hey folks, this is a bit OT: Do you know a good CI/CD system / technology / service which allows using a real programming language instead of YAML for expressing complex pipelines?? I just know of Jenkins Pipeline (Groovy), TeamCity (Kotlin Script) and Airflow (Python), but all of these have significant maintenance burden. I’d like to have something a la CircleCI but without YAML.

Funnily enough, I have been thinking a lot about that: https://github.com/pulumi/examples/tree/master/kubernetes-ts-staged-rollout-with-prometheus
