If you are doing a lot with docker images, it might be worth considering Concourse CI (https://concourse.ci). I haven't played with it in any depth yet so I'm not sure how it compares with other solutions, but I like the idea of your entire build pipeline running through docker images. Theoretically you should even be able to run it in kubernetes.

There's a github repo where someone mounted Concourse on kubernetes[0], but it looks a bit stale. Given the evolutionary pace of k8s, YMMV.

unfortunately concourse when not deployed with bosh does not have any automation (spawning workers, auto-discovery).
