+### kube-discovery
+
+An initial implementation of a Kubernetes discovery service using JSON Web Signatures.
+
+This prototype is configured by kubeadm and run within Kubernetes itself.
+
+## Requirements
+
+This pod expects the cluster CA, endpoints list, and token map to exist in /tmp/secret. This allows us to pass them in as kubernetes secrets when deployed as a pod.
+
+```
+$ cd /tmp/secret
+$ ls
+ca.pem  endpoint-list.json  token-map.json
+$ cat endpoint-list.json
+["http://192.168.1.5:8080", "http://192.168.1.6:8080"]
+$ cat token-map.json
+{
+    "TOKENID": "ABCDEF1234123456"
+}
+```
+
+## Build And Run From Source
+
+```
+$ build-tools/run.sh /bin/bash -c "KUBE_BUILD_PLATFORMS=linux/amd64 make WHAT=cmd/kube-discovery"
+$ _output/dockerized/bin/linux/amd64/kube-discovery
+2016/08/23 19:17:28 Listening for requests on port 9898.
+
+```
+
+## Running in Docker
+
+This image is published at: gcr.io/google_containers/kube-discovery
+
+`docker run -d -p 9898:9898 -v /tmp/secret/ca.pem:/tmp/secret/ca.pem -v /tmp/secret/endpoint-list.json:/tmp/secret/endpoint-list.json -v /tmp/secret/token-map.json:/tmp/secret/token-map.json --name kubediscovery gcr.io/google_containers/kube-discovery`
+
+## Testing the API
+
+`curl "http://localhost:9898/cluster-info/v1/?token-id=TOKENID"`
+
+You should see JSON containing a signed payload. For code to verify and decode that payload see handler_test.go.
