Jenkins is an utter utter arse, don't get me wrong. I would gladly pay for circleCI for 90% of usecases. We have > 90 jenkins masters here (don't ask) all in various states of rot. all of them are unceasingly tedious.

However, for getting a script to run on a certain bunch of nodes, at a certain time for given conditions, its pretty simple. (Unless you have a fetish for the myriad of unstable jenkins plugins)

K8s however isn't simple for that usecase. If I had to read the code and then push changes _before_ it worked for my usecase I'd have dropped it like a bag of sick.

However I do take your point that if no one pushes upstream then its not very fun at all.
