+	The --node-pools option allows you to pass in options for any number of
+	node pools when creating a cluster. The options are passed in a delimited
+	string.  Different node pools are delimited by a slash (/). The options for
+	each node pool are delimited by a comma (,) and each option is defined by
+	colon (:).  If provided, the node pool options can also parse out the
+	node-labels params which are delimited by a pipe (|).
+
+	Available options are documented in the 'kubernetes node-pool create --help' 
+
+	For example:
+
+	Multiple node pools
+	--node-pools="quantity:1,plan:vc2-4c-8gb,label:main-node-pool/quantity:5,plan:vc2-2c-4gb,label:worker-pool,auto-scaler:true,min-nodes:5,max-nodes:10"
+
+	Using node labels 
+	--node-pools="quantity:5,plan:vc2-2c-4gb,label:worker-pool,auto-scaler:true,min-nodes:5,max-nodes:10,node-labels:application=identity-service|worker-size=small"
