reconciler-logic

Implement a Kubernetes reconciler loop by writing a TypedReconciler that handles create, update, and delete events, using resource.UpdateObject for atomic status updates and requeueing to poll external async work. This prevents race conditions and status conflicts during asynchronous reconciliation.

409 conflicts during status updates happen when concurrent writes overwrite the resource version. Use resource.UpdateObject for atomic status updates to avoid 409 conflicts and ensure consistent status writes in your reconciler loop.

Manage finalizers in an async reconcile loop by adding them upon resource creation and removing them only after external cleanup completes. The reconciler logic handles finalizer management to ensure external resources are properly deleted before the custom resource is removed.

Use generation-based skips to ignore update events where the spec has not changed. By comparing resource generations, the reconciler avoids redundant processing and only executes business logic when actual spec modifications occur.

Configure informer retry and dequeue policies by setting parameters in your grafana-app-sdk application's informer configuration. These policies control how the controller handles transient failures and manages the rate of resyncs for robust production controllers.

Yes, you can use grafana-app-sdk to build a controller that kicks off an external provisioning job, polls its status, updates the resource status atomically, and cleans up external resources on deletion using requeueing and finalizer management.
