Building Native Kubernetes Integrations with Operators
summary
Builds a working “Panini as a Service” operator with Kubebuilder, showing the exact CRD fields, a reconcile loop that emits Kubernetes events and updates status, and a three‑command bootstrap that generates YAML, tests and installs the controller on a cluster. Explains using the fast fake client unit tests instead of the slow integration harness, running a real k3s instance for CI, exporting Prometheus metrics for reconcile error counts, and using Terraform to provision AWS creds; mentions a useful doc generator that surprisingly has only 58 stars.
