1. Create a VM running the cloud forms image.

2. 1. add a service account in openshift oadm new-project management-infra --description="Management Infrastructure"

   oc create -n management-infra -f - <<EOF apiVersion: v1 kind: ServiceAccount metadata: name: management-admin EOF

   oc create -f - <<EOF apiVersion: v1 kind: ClusterRole metadata: name: management-infra-admin rules:

   • resources:
     • pods/proxy verbs:
     • '*' EOF

   oadm policy add-role-to-user -n management-infra admin -z management-admin oadm policy add-role-to-user -n management-infra management-infra-admin -z management-admin oadm policy add-cluster-role-to-user cluster-reader -z management-admin oadm policy add-scc-to-user privileged system:serviceaccount:management-infra:management-admin

3. get the token for the service account:

    oc get -n management-infra sa/management-admin --template='{{range .secrets}}{{printf "%s\n" .name}}{{end}}'
   

   This returns:

    management-admin-dockercfg-xxxxxx
    management-admin-token-xxxxxx
   

   Use the management-admin-token-*

    oc get -n management-infra secrets management-admin-token-xxxxxx --template='{{.data.token}}' | base64 -d
   

   This returns the token.

4. Install/enable metrics using defaults and persistent storage:

   ansible-playbook /usr/share/ansible/openshift-ansible/playbooks/byo/openshift-cluster/openshift-metrics.yml
   -e openshift_metrics_install_metrics=True
   -e openshift_metrics_hawkular_hostname=hawkular-metrics.apps.osh.massopen.cloud
   -e openshift_metrics_cassandra_storage_type=pv

5. Deploy agents to the nodes:

   a) gather 2 config files:

    wget https://raw.githubusercontent.com/openshift/origin-metrics/enterprise/hawkular-openshift-agent/hawkular-openshift-agent-configmap.yaml
    wget https://raw.githubusercontent.com/openshift/origin-metrics/enterprise/hawkular-openshift-agent/hawkular-openshift-agent.yaml
   

   b) add to default project oc create -f hawkular-openshift-agent-configmap.yaml -n default oc create -f hawkular-openshift-agent.yaml -n default

6. Deploy the heapster endpoint (the router on the master) oadm router management-metrics
   -n default
   --service-account=router --ports='443:5000'
   --selector='kubernetes.io/hostname='
   --stats-port=1937
   --host-network=false
