[API reference docs](/federation/docs/api-reference/readme/) lists all the
resources supported by federation apiserver.
## Cascading deletion
Kubernetes version 1.5 includes support for cascading deletion of federated
resources. With cascading deletion, when you delete a resource from the
federation control plane, the corresponding resources in all underlying clusters
are also deleted.
To enable cascading deletion, set the option
`DeleteOptions.orphanDependents=false` when you delete a resource from the
federation control plane.
The following Federated resources are affected by cascading deletion:
* Ingress
* Namespace
* ReplicaSet
* Secret
* Deployment
* DaemonSet
Note: By default, deleting a resource from federation control plane does not
delete the corresponding resources from underlying clusters.
