At the Helm without a Steering Wheel – Your Chart as a Kubernetes Operator
summary
Shows how to convert an existing Helm chart into a runnable Kubernetes operator using the Operator SDK and a single command operator-sdk new --type helm --chart=stable/cockroachdb, packaging the unchanged chart into an image, scaffolding the CRD, RBAC and deployment, and deploying it to the cluster. Demo builds a CockroachDB operator, creates the CRD, applies a CR instance, and the operator reconciles and exposes release status. Notes: may need extra RBAC, use CI smoke tests, publish to Operator Hub.
