+# Kube-Registry with GCS storage backend
+
+Besides local file system, docker registry also supports a number of cloud storage backends. Full list of supported backend can be found [here](https://docs.docker.com/registry/configuration/#storage). This document describes how to enable GCS for kube-registry as storage backend. 
+
+A few preparation steps are needed. 
+ 1. Create a bucket named kube-registry in GCS.
+ 1. Create a service account for GCS access and create key file in json format. Detail instruction can be found [here](https://cloud.google.com/storage/docs/authentication#service_accounts).
+
+
+### Pack Keyfile into a Secret
+
+Assuming you have downloaded the keyfile as `keyfile.json`. Create secret with the `keyfile.json`...
+```console
+$ kubectl --namespace=kube-system create secret generic gcs-key-secret --from-file=keyfile=keyfile.json
+```
+
+
+### Run Registry
+

+        secret:
+          secretName: gcs-key-secret
+```
+<!-- END MUNGE: EXAMPLE registry-gcs-rc.yaml -->
+
+
+No changes are needed for other components (kube-registry service and proxy).
