# == Define: tripleo::pacemaker::haproxy_with_vip
#
# Configure the vip with the haproxy under pacemaker
#
# === Parameters:
#
# [*vip_name*]
#  (String) Logical name of the vip (control, public, storage ...)
#  Required
#
# [*ip_address*]
#  (String) IP address on which HAProxy is colocated
#  Required
#
# [*ensure*]
#  (Boolean) Create the all the resources only if true.  False won't
#  destroy the resource, it will just not create them.
#  Default to true
