# == Define: tripleo::firewall::service_rules
#
# Define used to create firewall rules for composable services.
#
# === Parameters:
#
# [*service_name*]
# (optional) The service_name to load firewall rules for.
# Defaults to $title
#
define tripleo::firewall::service_rules ($service_name = $title) {
$underscore_name = regsubst($service_name, '-', '_')
# This allows each composable service to load its own custom rules by
# creating its own flat hiera key named:
# tripleo.<service name with underscores>.firewall_rules
$dots_rules = hiera("tripleo.${underscore_name}.firewall_rules", {})
# Supports standard "::" notation:
# tripleo::<service name with underscores>::firewall_rules
$colons_rules = hiera("tripleo::${underscore_name}::firewall_rules", {})
# merge rules
$firewall_rules = merge($colons_rules, $dots_rules)
