Finalizer

Glossary Page

Finalizers are keys that you can add to Kubernetes objects to instruct the system to wait until certain conditions are met before deleting the objects. They are used to ensure that the objects are cleaned up correctly and that any dependent resources are also deleted. When you delete an object with finalizers, Kubernetes marks the object for deletion and enters a terminating state. The control plane and other components then execute any actions defined by the finalizers. Once these actions are complete, the finalizers are removed, and Kubernetes deletes the object. Finalizers are useful for controlling the garbage collection of resources, allowing you to clean up related resources or infrastructure before deleting the target resource.
