+#### Run on Openshift
+
+In order to deploy the exporter on Openshift environment.
+```
+oc project <myproject>
+
+oc process -f https://raw.githubusercontent.com/ivanovaleksandar/redis_exporter/master/contrib/openshift-template.yaml \
+    -p REDIS_ADDR=<redis-service>:<redis-port> \
+    -p REDIS_PASSWORD=<redis-pass> \
+    -p REDIS_ALIAS=<redis-alias> \
+    -p REDIS_FILE=<redis-file> \
+    | oc create -f -
+```
+
+*NOTE*: Some of the parameters can be ommited if no authentication is used or the default redis config is applied.

+If you are running Prometheus on Openshift on the same cluster, **target** in `prometheus.yml` should point to the correct service name of the exporter
