We used Drone [1] from a while. It's almost exactly what I want in a CI/CD system, and it runs pretty well on Kubernetes.

On the minus side, the development has been slow, with major breaking changes happening along the way. And in the latest version, the open-source version has been a bit hobbled. In particular, it doesn't support global secrets, so every project to be built has to be created and managed separately. This is not just if it needs build secrets (such as to access private Go packages, NPM modules, Ruby gems, etc.), but it's obviously also required to authenticate with a container registry. We decided to skip that since it means duplicating the same secrets for every single application. We actually reached out to the Drone guys to ask about enterprise pricing, but they didn't respond (!).

(At the moment we're back to building with Semaphore, which is a hosted solution similar to Travis. It's an old-hat CI system that spins up VMs, so it's slow and awkward to work with when it comes to Docker. But it's working okay at the moment.)

I've heard good things about GoCD [2], though. It's next on my list to investigate.
