Overview

systemd service support

Module Description

basic systemd support implemented:

• service definitions
• logind.conf (disables IPC deletion on user logout)

Setup

What systemd affects

• Creates service definitions: /etc/systemd/system/${servicename}.service
• Manages /etc/systemd/logind.conf

Setup Requirements

This module requires pluginsync enabled

Beginning with systemd

basic example from eyp-kibana:

systemd::service { 'kibana':
  execstart => "${basedir}/${productname}/bin/kibana",
  require   => [ Class['systemd'], File["${basedir}/${productname}/config/kibana.yml"] ],
  before => Service['kibana'],
}

Usage

add service dependency:

systemd::service { 'oracleasm':
  description       => 'Load oracleasm Modules',
  after             => 'iscsi.service',
  type              => 'oneshot',
  remain_after_exit => true,
  execstart         => '/usr/sbin/service oracleasm start_sysctl',
  execstop          => '/usr/sbin/service oracleasm stop_sysctl',
  execreload        => '/usr/sbin/service oracleasm restart_sysctl',
}

Limitations

Should work anywhere, tested on CentOS 7

Development

We are pushing to have acceptance testing in place, so any new feature should have some test to check both presence and absence of any feature
