# == Class: tripleo
#
# Configure the TripleO firewall
#
# === Parameters:
#
# [*manage_firewall*]
# (optional) Completely enable or disable firewall settings
# (false means disabled, and true means enabled)
# Defaults to false
#
# [*firewall_rules*]
# (optional) Allow to add custom firewall rules
# Should be an hash.
# Default to {}
#
# [*purge_firewall_rules*]
# (optional) Boolean, purge all firewall resources
# Defaults to false
#
# [*firewall_pre_extras*]
# (optional) Allow to add custom parameters to firewall rules (pre stage)
# Should be an hash.
# Default to {}
#
# [*firewall_post_extras*]
# (optional) Allow to add custom parameters to firewall rules (post stage)
# Should be an hash.
# Default to {}
#

# anyone can add your own rules
# example with Hiera:
#
# tripleo::firewall::rules:
# '300 allow custom application 1':
# port: 999
# proto: udp
# action: accept
# '301 allow custom application 2':
# port: 8081
# proto: tcp
# action: accept
#
create_resources('tripleo::firewall::rule', $firewall_rules)

'firewall_settings' => $firewall_pre_extras,
'stage' => 'setup',

'firewall_settings' => $firewall_post_extras,

# Allow composable services to load their own custom
# example with Hiera.
# NOTE(dprince): In the future when we have a better hiera
# heat hook we might refactor this to use hiera's merging
# capabilities instead. Until then rolling up the flat service
# keys and dynamically creating firewall rules for each service
# will allow us to compose and should work fine.
#
# Each service can load its rules by using this form:
#
# tripleo.<service name with underscores>.firewall_rules:
# '300 allow custom application 1':
# dport: 999
# proto: udp
# action: accept
$service_names = reject(hiera('service_names', []), '^$')
