+# Enable Authentication with Htpasswd for Kube-Registry 
+
+Docker registry support a few authentication providers. Full list of supported provider can be found [here](https://docs.docker.com/registry/configuration/#auth). This document describes how to enable authentication with htpasswd for kube-registry. 
+
+### Prepare Htpasswd Secret
+
+Please generate your own htpasswd file. Assuming the file you generated is `htpasswd`. 
+Creating secret to hold htpasswd...
+```console
+$ kubectl --namespace=kube-system create secret generic registry-auth-secret --from-file=htpasswd=htpasswd
+```
+
+### Run Registry
+
+Please be noted that this sample rc is using emptyDir as storage backend for simplicity. 
+

+        emptyDir: {}
+      - name: auth-dir
+        secret:
+          secretName: registry-auth-secret
+```
+<!-- END MUNGE: EXAMPLE registry-auth-rc.yaml -->
+
+No changes are needed for other components (kube-registry service and proxy). 
+
+### To Verify
+
+Setup proxy or port-forwarding to the kube-registry. Image push/pull should fail without authentication. Then use `docker login` to authenticate with kube-registry and see if it works.
+
+### Configure Nodes to Authenticate with Kube-Registry
+
+By default, nodes assume no authentication is required by kube-registry. Without authentication, nodes cannot pull images from kube-registry. To solve this, more documentation can be found [Here](https://github.com/kubernetes/kubernetes/blob/master/docs/user-guide/images.md#configuring-nodes-to-authenticate-to-a-private-repository)
