Ask HN: Good examples of Kubernetes operators codebase?

19 points by Kreotiko ↗ HN
Hi all, I am playing around with the operatorsdk and I would really benefit to dig in codebases implementing it.

I am interested in good examples not necessarily using the operatorSDK for this.

Most likely prometheus-operator , very active and production utilized https://prometheus-operator.dev

If it has to be about operator sdk then it’s not the best example because it doesn’t use operator sdk, it uses the lower level client-go directly (I’m just commenting this because the original post was asking about operator sdk). I personally prefer client-go, the operator sdk interface never really spoke to me.

(Full disclosure, I’m the co-creator and one of the maintainers of prometheus operator)

I am the person who asked and I was probably unclear. I mentioned the operator sdk because that is what I am trying at the moment but I am open to other approaches so this example is welcome

In that case I recommend using client-go directly. In my admittedly limited experience with operator sdk (which was created long after the Prometheus operator), it tries to abstract a lot of things to make things like working with operator lifecycle manager (OLM) easier, but also causes a lot of (to me) unnatural interfaces and sometimes downright prevented me from doing things I needed to do because things were abstracted and hidden too much. We’ve attempted to migrate Prometheus operator several times but never successfully.
