+OpenShift Metrics with Hawkular
+====================
+
+OpenShift Metrics Installation
+
+Requirements
+------------
+
+The following variables need to be set and will be validated:
+
+- `openshift_metrics_hostname`: hostname used on the hawkular metrics route.
+
+- `openshift_metrics_project`: project (i.e. namespace) where the components will be
+  deployed.
+
+
+Role Variables
+--------------
+
+For default values, see [`defaults/main.yaml`](defaults/main.yaml).
+
+- `openshift_metrics_image_prefix`: Specify prefix for metrics components; e.g for
+  "openshift/origin-metrics-deployer:v1.1", set prefix "openshift/origin-".
+
+- `openshift_metrics_image_version`: Specify version for metrics components; e.g. for
+  "openshift/origin-metrics-deployer:v1.1", set version "v1.1".
+
+- `openshift_metrics_hawkular_cert:` The certificate used for re-encrypting the route
+  to Hawkular metrics.  The certificate must contain the hostname used by the route.
+  The default router certificate will be used if unspecified
+
+- `openshift_metrics_hawkular_key:` The key used with the Hawkular certificate
+
+- `openshift_metrics_hawkular_ca:` An optional certificate used to sign the Hawkular certificate.
+
+- `openshift_metrics_hawkular_replicas:` The number of replicas for Hawkular metrics.
+
+- `openshift_metrics_cassandra_replicas`: The number of Cassandra nodes to deploy for the
+  initial cluster.
+
+- `openshift_metrics_cassandra_storage_type`: Use `emptydir` for ephemeral storage (for
+  testing), `pv` to use persistent volumes (which need to be created before the
+  installation) or `dynamic` for dynamic persistent volumes.
+
+- `openshift_metrics_cassandra_pv_prefix`: The name of persistent volume claims created
+  for cassandra will be this with a serial number appended to the end, starting
+  from 1.
+
+- `openshift_metrics_cassandra_pv_size`: The persistent volume size for each of the
+  Cassandra  nodes.
+
+- `openshift_metrics_heapster_standalone`: Deploy only heapster, without the Hawkular Metrics and
+  Cassandra components.
+
+- `openshift_metrics_heapster_allowed_users`: A comma-separated list of CN to accept.  By
+  default, this is set to allow the OpenShift service proxy to connect.  If you
+  override this, make sure to add `system:master-proxy` to the list in order to
+  allow horizontal pod autoscaling to function properly.
+
+- `openshift_metrics_startup_timeout`: How long in seconds we should wait until
+  Hawkular Metrics and Heapster starts up before attempting a restart.
+
+- `openshift_metrics_duration`: How many days metrics should be stored for.
+
+- `openshift_metrics_resolution`: How often metrics should be gathered.
+
+## Additional variables to control resource limits
+Each metrics component (hawkular, cassandra, heapster) can specify a cpu and memory limits and requests by setting
+the corresponding role variable:
+```
+openshift_metrics_<COMPONENT>_(limits|requests)_(memory|cpu): <VALUE>
+```
+e.g
+```
+openshift_metrics_cassandra_limits_memory: 1G
+openshift_metrics_hawkular_requests_cpu: 100
+```
+
+Dependencies
+------------
+openshift_facts
