Can you list the main cascading operations present in Kubernetes?

In Kubernetes, cascading operations are usually related to resource deletion and managing dependencies between them. The main cascading operations include:

• Cascading Delete — when an object, such as a Deployment, is deleted, all related child objects, such as ReplicaSets and Pods, are automatically deleted.
• Foreground Deletion — the object is deleted only after all child objects have been deleted.
• Background Deletion — the object is deleted immediately, and child objects are deleted asynchronously in the background.
• Orphan Deletion — when a parent object is deleted, child objects remain unchanged (are not deleted).

Example of deleting a Deployment with cascading deletion in the background:

kubectl delete deployment my-deployment --cascade=background

Thus, cascading operations help manage the lifecycle of related resources in Kubernetes.
