+# Example: managing neutron controller services with pacemaker
+#
+# By setting enabled to false, these services will not be started at boot.  By setting
+# manage_service to false, puppet will not kill these services on every run.  This
+# allows the Pacemaker resource manager to dynamically determine on which node each
+# service should run.
+#
+# The puppet commands below would ideally be applied to at least three nodes.
+#
+# Note that neutron-server is associated with the virtual IP address as
+# it is called from external services.  The remaining services connect to the
+# database and/or message broker independently.
+#
+# Example pacemaker resource configuration commands (configured once per cluster):
+#
+# sudo pcs resource create neutron_vip ocf:heartbeat:IPaddr2 params ip=192.0.2.3 \
+#   cidr_netmask=24 op monitor interval=10s
+#
+# sudo pcs resource create neutron_server_service lsb:neutron-server
+# sudo pcs resource create neutron_dhcp_agent_service lsb:neutron-dhcp-agent
+# sudo pcs resource create neutron_l3_agent_service lsb:neutron-l3-agent
+#
+# sudo pcs constraint colocation add neutron_server_service with neutron_vip
