+# Apache Zookeeper (Experimental)
+
+
+### Info:
+
+ This template creates, scale in and scale out a multinodes zk (zookeeper) cluster on top of Rancher. The configuration is generated with confd from Rancher metadata. 
+ Cluster size are variable after deployment, and get reconfigured if refresh interval > 0.
+ 
+ 
+### Usage:
+
+ Select Apache Zookeeper from catalog. 
+ 
+ Enter the number of nodes, mem and refresh interval for the zk cluster. (set refresh data to 0 to disable dinamic config)
+
+ Note: When you scale the cluster, zero downtime is not guaranteed..yet..
+ 
+ Click deploy.
+ 
+ Zookeeper can now be accessed over the Rancher network.
