# == 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
#
# [*location_rule*]
# (optional) Add a location constraint before actually enabling
# the resource. Must be a hash like the following example:
# location_rule => {
# resource_discovery => 'exclusive', # optional
# role => 'master|slave', # optional
# score => 0, # optional
# score_attribute => foo, # optional
# # Multiple expressions can be used
# expression => ['opsrole eq controller']
# }
# Defaults to undef
#
# [*pcs_tries*]
# (Optional) The number of times pcs commands should be retried.
# Defaults to 1
#
# [*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
#
