+OpenShift Prometheus
+====================
+
+OpenShift Prometheus Installation
+
+Requirements
+------------
+
+
+Role Variables
+--------------
+
+For default values, see [`defaults/main.yaml`](defaults/main.yaml).
+
+- `openshift_prometheus_state`: present - install/update. absent - uninstall.
+
+- `openshift_prometheus_namespace`: project (i.e. namespace) where the components will be
+ deployed.
+
+- `openshift_prometheus_node_selector`: Selector for the nodes prometheus will be deployed on.
+
+- `openshift_prometheus_<COMPONENT>_image_prefix`: specify image prefix for the component
+
+- `openshift_prometheus_<COMPONENT>_image_version`: specify image version for the component
+
+## PVC related variables
+Each prometheus component (prometheus, alertmanager, alertbuffer) can set pv claim by setting corresponding role variable:
+```
+openshift_prometheus_<COMPONENT>_storage_type: <VALUE> (pvc, emptydir)
+openshift_prometheus_<COMPONENT>_pvc_(name|size|access_modes|pv_selector): <VALUE>
+```
+e.g
+```
+openshift_prometheus_storage_type: pvc
+openshift_prometheus_alertmanager_pvc_name: alertmanager
+openshift_prometheus_alertbuffer_pvc_size: 10G
+openshift_prometheus_pvc_access_modes: [ReadWriteOnce]
+```
+
+## NFS PV Storage variables
+Each prometheus component (prometheus, alertmanager, alertbuffer) can set nfs pv by setting corresponding variable:
+```
+openshift_prometheus_<COMPONENT>_storage_kind=<VALUE>
+openshift_prometheus_<COMPONENT>_storage_(access_modes|host|labels)=<VALUE>
+openshift_prometheus_<COMPONENT>_storage_volume_(name|size)=<VALUE>
+openshift_prometheus_<COMPONENT>_storage_nfs_(directory|options)=<VALUE>
+```
+e.g
+```
+openshift_prometheus_storage_kind=nfs
+openshift_prometheus_storage_access_modes=['ReadWriteOnce']
+openshift_prometheus_storage_host=nfs.example.com #for external host
+openshift_prometheus_storage_nfs_directory=/exports
+openshift_prometheus_storage_alertmanager_nfs_options='*(rw,root_squash)'
+openshift_prometheus_storage_volume_name=prometheus
+openshift_prometheus_storage_alertbuffer_volume_size=10Gi
+openshift_prometheus_storage_labels={'storage': 'prometheus'}
+```
+
+NOTE: Setting `openshift_prometheus_<COMPONENT>_storage_labels` overrides `openshift_prometheus_<COMPONENT>_pvc_pv_selector`
+
+
+## Additional Alert Rules file variable
+An external file with alert rules can be added by setting path to additional rules variable:
+```
+openshift_prometheus_additional_rules_file: <PATH>
+```
+
+File content should be in prometheus alert rules format.
+Following example sets rule to fire an alert when one of the cluster nodes is down:
+
+```
+groups:
+- name: example-rules
+ interval: 30s # defaults to global interval
+ rules:
+ - alert: Node Down
+ expr: up{job="kubernetes-nodes"} == 0
+ annotations:
+ miqTarget: "ContainerNode"
+ severity: "HIGH"
+ message: "{{ '{{' }}{{ '$labels.instance' }}{{ '}}' }} is down"
+```
+
+
+## Additional variables to control resource limits
+Each prometheus component (prometheus, alertmanager, alert-buffer, oauth-proxy) can specify a cpu and memory limits and requests by setting
+the corresponding role variable:
+```
+openshift_prometheus_<COMPONENT>_(limits|requests)_(memory|cpu): <VALUE>
+```
+e.g
+```
+openshift_prometheus_alertmanager_limits_memory: 1Gi
+openshift_prometheus_oath_proxy_requests_cpu: 100
+```
+
+Dependencies
+------------
+
+openshift_facts
+
+
+Example Playbook
+----------------
+
+```
+- name: Configure openshift-prometheus
+ hosts: oo_first_master
+ roles:
+ - role: openshift_prometheus
