Writing a Kubernetes/Openshift Operators Using Golang
summary
Shows how to build a real Go operator with the operator-framework and operator-sdk, register a CustomResourceDefinition and CSV for OLM, and wire a controller that implements the reconciliation loop. Demo creates CRs locally, the operator creates/updates Kubernetes resources (Services, Deployments), supports multi‑instance installs and namespace-scoped watching, and shows install/uninstall via generated manifest and CSV. Includes concrete code paths for desired vs observed state, tests for reconcilers, and local development steps that actually run.
