[kubernetes-users] Kuberntes/Prometheus - Unable to Annotate in service file

[ijunaidsubhani]

My Kubernetes versions is ::

    # kubectl --version
    Kubernetes v1.4.0


I am planning to use prometheus to monitor my Kube cluster. For this, I need to 
annotate the metrics URL.

My current metrics URL is like :

    http://172.16.33.7:8080/metrics

But I want it like :

    http://172.16.33.7:8080/websocket/metrics

First I tried to do this manually ::

    kubectl annotate pods 
websocket-backend-controller-db83999c5b534b277b82badf6c152cb9m1 
prometheus.io/path=/websocket/metrics
    kubectl annotate pods 
websocket-backend-controller-db83999c5b534b277b82badf6c152cb9m1 
prometheus.io/scrape='true'
    kubectl annotate pods 
websocket-backend-controller-db83999c5b534b277b82badf6c152cb9m1 
prometheus.io/port='8080' 

All these commands work perfectly fine and I am able to see the annotations.

    {
      "metadata": {
        "name": "websocket-backend-controller-v1krf",
        "generateName": "websocket-backend-controller-",
        "namespace": "default",
        "selfLink": 
"/api/v1/namespaces/default/pods/websocket-backend-controller-v1krf",
        "uid": "e323994b-4081-11e7-8bd0-0050569b6f44",
        "resourceVersion": "27534379",
        "creationTimestamp": "2017-05-24T13:07:06Z",
        "labels": {
          "name": "websocket-backend"
        },
        "annotations": {
          "kubernetes.io/created-by": 
"{\"kind\":\"SerializedReference\",\"apiVersion\":\"v1\",\"reference\":{\"kind\":\"ReplicationController\",\"namespace\":\"default\",\"name\":\"websocket-backend-controller\",\"uid\":\"e321f1a8-4081-11e7-8bd0-0050569b6f44\",\"apiVersion\":\"v1\",\"resourceVersion\":\"27531840\"}}\n",
          "prometheus.io/path": "/websocket/metrics",
          "prometheus.io/port": "8080",
          "prometheus.io/scrape": "true"
        }

But since I want these configs to remain permanent, I am configuring them in my 
services files.

    # cat websocket-service.yaml 
    apiVersion: v1
    kind: Service
    metadata:
      name: websocket-service
      labels:
        baseApi: websocket
      annotations:
        prometheus.io/scrape: 'true'
        prometheus.io/path: /websocket/metrics
        prometheus.io/port: '8080'
    spec:
      selector:
        name: websocket-backend
      ports:
        - port: 8080
          targetPort: 8080
          nodePort: 30800
          protocol: TCP
      type: NodePort
      clusterIP: 10.100.10.45

I restarted my websocket service and the corresponding pods but these configs 
dont seem to be taking effect.

    kubectl create -f websocket-service.yaml
    kubectl create -f ../controllers/websocket-replication-controller.yaml

The result does not show the annotations configured.

    {
          "metadata": {
            "name": "websocket-backend-controller-v1krf",
            "generateName": "websocket-backend-controller-",
            "namespace": "default",
            "selfLink": 
"/api/v1/namespaces/default/pods/websocket-backend-controller-v1krf",
            "uid": "e323994b-4081-11e7-8bd0-0050569b6f44",
            "resourceVersion": "27531879",
            "creationTimestamp": "2017-05-24T13:07:06Z",
            "labels": {
              "name": "websocket-backend"
            },
            "annotations": {
              "kubernetes.io/created-by": 
"{\"kind\":\"SerializedReference\",\"apiVersion\":\"v1\",\"reference\":{\"kind\":\"ReplicationController\",\"namespace\":\"default\",\"name\":\"websocket-backend-controller\",\"uid\":\"e321f1a8-4081-11e7-8bd0-0050569b6f44\",\"apiVersion\":\"v1\",\"resourceVersion\":\"27531840\"}}\n"
            }

All Im doing is rather than using a command line, I am setting the configs 
using services config but it does not seem to be working.
