+# Consul-Registrator
+
+### Info:
+
+This templates creates a global service that deploys a Consul agent that is bound to the host's networking.
+This allows all Rancher hosts to join an existing Consul cluster.
+
+Additionally, Registrator is deployed to automatically discover and register containers that are deployed on the host as Consul service entries.
+This allows for automatic service registration in Consul as Rancher schedule containers in the cluster.
+
+ The variables used in this template include:
+
+- Hostname or IP address for the Consul cluster to join
+
+The templates uses the official Consul & Registrator images
+
+- [consul](https://hub.docker.com/r/_/consul/).
+- [registrator](https://hub.docker.com/r/gliderlabs/registrator/).
+
+### Usage:
+
+ Select Consul from catalog.
+
+ Enter the hostname/DNS name/IP address of the Consul server to join
+
+ Click deploy.
