+# Apache Zookeeper (Experimental)
+
+### Info:
+
+ This template creates, scale in and scale out a multinodes zk (zookeeper) cluster on top of k8s. The configuration is generated with confd watching k8s metadata. 
+ Cluster size are variable after deployment, and get reconfigured if you scale.
+
+ The services generates ZKID's (saving them as pod labels) and start the zookeeper cluster.
+ 
+ 
+### Usage:
+
+ Select Apache Zookeeper from catalog. 
+
+ Change the following zookeeper default parameters, if you need:
+
+- zk_name="zookeeper"			# Name of the k8s rc and service.
+- zk_namespace="default"		# Name of the k8s namespace
+- zk_scale="3"					# Number of zk replicas
+- zk_mem="512"					# Mem to configure zk.
+- zk_data_dir="/opt/zk/data"	# Zk dataDir param value
+- zk_init_limit="10"			# zk initLimit param value
+- zk_max_client_cxns="500"		# zk maxClientCnxns param value
+- zk_sync_limit="5"				# zk syncLimit param value
+- zk_tick_time="2000"			# zk tickTime param value
+ 
+ Click deploy.
+ 
+ Zookeeper can now be accessed over the Rancher network. 
+
+Testing Feature: When you scale the cluster, zero downtime is expected...
