What are the best practices for using finalizers in Kubernetes?

Best practices for using finalizers include ensuring idempotency, handling deletion gracefully, and avoiding blocking operations.

Can you explain what idempotency means in this context?

Idempotency means that performing the same operation multiple times will have the same effect as performing it once, which is crucial for finalizers.

What should I do if a finalizer is blocking the deletion of a resource?

You should investigate the finalizer's logic, ensure it completes successfully, or consider removing the finalizer if it's no longer needed.

Are there any common pitfalls to avoid when using finalizers?

Yes, common pitfalls include not handling errors properly, creating circular dependencies, and not cleaning up resources after use.
