DigitalOcean Kubernetes: Support for Optional Cascading Deletes
When you delete a Kubernetes cluster via the Delete Cluster endpoint, only the cluster and the worker node droplets are deleted.
To delete the cluster and all its associated resources (volumes, volume snapshots and load balancers), use the dangerous delete endpoint.
To delete a Kubernetes cluster along with a subset of its associated resources, use the delete selective endpoint.
To list the IDs of the associated resources for selective deletion, use the list associated resources endpoint.
