+##Optional
+- influxdb_bind_address - address to be used for binding the influxdb ports. Default is to bind to all IP addresses.
+- run_mode - One of Deploy, Stop, Install, Start, or Use. The default is Deploy which will do Install, Configure, then Start.
 
-    - hosts: servers
-      roles:
-         - stympy.influxdb
+### Clustering
+To enable clustering define `influxdb_peers` on all nodes.
+`influxdb_peers` is a list of `host:port` entries, one for each node.
