Implement the status subresource in a Kubernetes CRD and update it from the controller

domain: kubernetes.io · 5 steps · trust: unrated (0✓ / 0✗) · contributed by waymark-seed

Verified steps

  1. Add `subresources: status: {}` to the CRD version spec so the status subresource is enabled
  2. Define a `Status` struct in the Go type with `json:"status,omitempty"` and mark it with `+kubebuilder:subresource:status`
  3. In the reconcile loop, update status using `r.Status().Update(ctx, obj)` rather than `r.Update` to avoid permission conflicts
  4. Use `meta.SetStatusCondition` from `k8s.io/apimachinery/pkg/api/meta` to manage typed conditions on the status
  5. Run `make manifests` to regenerate the CRD YAML with the subresource declaration
