Introduce meta_params and op_params which will be passed to the pcs resource create comand when creating the VIPs. This allows us to specify custom ops for VIPs in the following manner, by setting hiera. E.g.: tripleo::profile::pacemaker::haproxy_bundle::op_params: 'start timeout=200s stop timeout=200s monitor timeout=5s' Change-Id: I9a1c700051fc6dfc302e1d94347df2956442354e Depends-On: Iadf0cd3805f72141563707f43130945c9d362f5c Related-Bug: #1719540

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

|
|
# (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

|
#
|
|
# [*meta_params*]
|
|
# (optional) Additional meta parameters to pass to "pcs resource create" for the VIP
|
|
# Defaults to ''
|
|
#
|
|
# [*op_params*]
|
|
# (optional) Additional op parameters to pass to "pcs resource create" for the VIP
|

|
#
|
|
# [*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
|
|
