What is the difference between finalizers and deletion protection?

What is the difference between finalizers and deletion protection in Kubernetes?

Finalizers are used to control the deletion process of resources, ensuring certain cleanup actions are completed before deletion. Deletion protection, on the other hand, prevents a resource from being deleted altogether.

Can you give me an example of how finalizers work?

Sure! When you delete a resource with a finalizer, the finalizer's logic runs first, allowing you to perform tasks like cleaning up related resources before the actual deletion occurs.

What happens if a finalizer fails?

If a finalizer fails, the resource will not be deleted until the finalizer is removed or the failure is resolved. This ensures that important cleanup tasks are completed.

Is deletion protection a good practice?

Yes, deletion protection is a good practice for critical resources to prevent accidental deletions, especially in production environments.
