Extending Kubernetes 101
summary
Shows how to design a CRD schema, run Kubernetes 1.8’s code generators to produce a strongly typed clientset/informers/deepcopy set, implement an operator in Go with simple add update delete handlers, build a Go binary, containerize with Docker, load the image into Minikube and run it with a ServiceAccount, ClusterRole and Deployment. Demo verifies the controller logs on create/update/delete. Notes that Rook implements five CRDs and operator-kit is used for boilerplate.
