At work we are using nolar/kopf for writing controllers that provisions/manages our kubernetes clusters. This also includes managing any infrastructure related apps that we deploy on them.

We were using whitebox controller at the start, which is also like metacontroller that runs your scripts on kubernetes events. That was easy to write. However not having full control on the lifecycle of the controller code gets in the way time to time.

Considering you are also writing Python did you review kopf before deciding on metacontroller?
