We're collaborating with the kubebuilder[0] project upstream, which is a subproject of SIG API Machinery that focuses on generating the best scaffolding for controllers. Myself and some Googlers also proposed creating a SIG focusing on platform extensions to Kubernetes, such as operators tooling[1]. The steering committee is currently not convinced that it merits a dedicated SIG, despite the many projects in the wild experimenting without organization. We're fully committed to taking well understood, community-accepted opinions from our tooling and upstreaming the work, if the community can agree on that aspect of the framework. A great example of this is the Application Definition Working Group, which has leveraged many ideas from our Operator Lifecycle Manager; our CRDs are practically the same! Now that things are open source, we should see things like these converge entirely.
