# == Define: tripleo::pacemaker::haproxy_with_vip
|
|
#
|
|
# Configure the vip with the haproxy under pacemaker
|
|

|
# 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

|
#
|
|
# [*meta_params*]

|
#
|
|
# [*op_params*]

# Defaults to ''
|
|
#
|
|
# [*pcs_tries*]
|
|
# (Optional) The number of times pcs commands should be retried.

|
#
|
|
# [*ensure*]
|
