btw. even gitlab does that with their autodevops, besides that they create gitlab-runner:

I found these fascinating, I mean they still have lots of things in their ci file, but basically the have tons of shell scripts that would work without their gitlab-runner.

Not affiliated with gitlab I just tried to figure out how some of their stuff works to have the same k8s integration than their autodevops offers.
