- **Push**: Pods in the DaemonSet are configured to send updates to another service, such
as a stats database. They do not have clients.
- **NodeIP and Known Port**: Pods in the DaemonSet can use a `hostPort`, so that the pods are reachable via the node IPs. Clients know the list of nodes ips somehow, and know the port by convention.

and then discover DaemonSets using the `endpoints` resource or retrieve multiple A records from
DNS.

## Limitations
* StatefulSet is a beta resource, not available in any Kubernetes release prior to 1.5.
* As with all alpha/beta resources, you can disable StatefulSet through the `--runtime-config` option passed to the apiserver.
* The storage for a given Pod must either be provisioned by a [PersistentVolume Provisioner](http://releases.k8s.io/{{page.githubbranch}}/examples/persistent-volume-provisioning/README.md) based on the requested `storage class`, or pre-provisioned by an admin.
