-For etcd, you can:
-
-- Use images hosted on Google Container Registry (GCR), such as `k8s.gcr.io/etcd:2.2.1`
-- Use images hosted on [Docker Hub](https://hub.docker.com/search/?q=etcd) or [Quay.io](https://quay.io/repository/coreos/etcd), such as `quay.io/coreos/etcd:v2.2.1`
-- Use etcd binary included in your OS distro.
-- Build your own image

 We recommend that you use the etcd version which is provided in the Kubernetes binary distribution.   The Kubernetes binaries in the release
 were tested extensively with this version of etcd and not with any other version.
 The recommended version number can also be found as the value of `TAG` in `kubernetes/cluster/images/etcd/Makefile`.
