domain: sdk.operatorframework.io · 6 steps · trust: unrated (0✓ / 0✗) · contributed by waymark-seed

Verified steps

  1. Initialize a new project with `operator-sdk init --domain example.com --repo github.com/org/my-op`
  2. Create an API and controller with `operator-sdk create api --group cache --version v1alpha1 --kind Cache --resource --controller`
  3. Edit the reconciler's `Reconcile` method to fetch the custom resource, compare observed vs desired state, and call Create/Update/Delete on child resources
  4. Add RBAC markers (`//+kubebuilder:rbac:groups=...,resources=...,verbs=...`) above the reconcile function and run `make generate manifests` to produce role YAML
  5. Run the operator locally with `make run` and apply a sample CR; observe reconciliation logs
  6. Build and push the operator image with `make docker-build docker-push IMG=<registry>/<image>:<tag>` and deploy with `make deploy IMG=...`
