# limitations under the License.
# == Class: ciwatch
#
# Deploy CI Watch monitoring dashboard.
#
# The dashboard consists of two services: gerrit listener (ciwatcher) and ui
# (ciwatch). The puppet module would not start these automatically and it is
# expected other means to be used.
# To manually start both:
# service ciwatch start
# service ciwatcher start
#
# Dashboard's UI would be accessible on port 5000 (flask's default).
#
# === Parameters
#
# [*gerrit_user*]
# Gerrit user account to be used by gerrit listener.
#
# [*ssh_private_key*]
# Contents of ssh private key. This key needs to be authorized to connect
# to gerrit account.
#
# [*gerrit_hostname*]
# Gerrit server to be used for ciwatch gerrit listener.
#
# [*gerrit_port*]
# Gerrit server port, default 29418.
#
#
# === Examples
#
# class { '::ciwatch':
# gerrit_user => hiera('ciwatch::gerit_user'),
# ssh_private_key => hiera('ciwatch::ssh_private_key'),
# mysql_password => hiera('ciwatch::mysql_password'),
# mysql_root_password => hiera('ciwatch::mysql_root_password'),
