+# Event Store cluster in rancher
+
+
+### Info:
+
+Best practice is to create a cluster of 3 nodes, but for this, you'll need at least 3 machines on your rancher cluster since the same external host port is used for each EventStore container.
+
+
+This template is not maintained by the EventStore team (https://geteventstore.com/) so do not buzz Greg Y.
+If it's not working, blame to commiter of this lines : Jérôme Rx, and make a pull request to improve this template.
