+# Example: managing nova compute 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 nova-api and nova-novncproxy are associated with the virtual IP address as
+# they are 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 nova_vip ocf:heartbeat:IPaddr2 params ip=192.0.2.3 \
+#   cidr_netmask=24 op monitor interval=10s
+#
+# sudo pcs resource create nova_api_service lsb:openstack-nova-api
+# sudo pcs resource create nova_conductor_service lsb:openstack-nova-conductor
+# sudo pcs resource create nova_consoleauth_service lsb:openstack-nova-consoleauth
+# sudo pcs resource create nova_novncproxy_service lsb:openstack-nova-novncproxy
+# sudo pcs resource create nova_scheduler_service lsb:openstack-nova-scheduler
+#
+# sudo pcs constraint colocation add nova_api_service with nova_vip
+# sudo pcs constraint colocation add nova_novncproxy_service with nova_vip
