Set up and manage Synergy on an existing OpenStack instance.

Module Description

Users that already have an OpenStack instance can use this module to install and configure the two main Synergy components:

This module will download the latest version of Synergy and install it. One can manage Synergy configuration directly through this module.


What synergy affects

  • Synergy configuration file at /etc/synergy/synergy.conf
  • packages synergy-service (rpm or deb depending on the platform) and synergy-scheduler-manager (via pip)

Setup Requirements

An OpenStack instance (with the version specified in Limitations).

The Puppet module puppetlabs/apt if you plan to install on Ubuntu.

An OpenStack package repository for fetching python-oslo* libraries:

  • on Ubuntu, use the OpenStack/CloudArchive repository.
  • on CentOS, the CentOS Cloud SIG repository will be installed during the Puppet run through the centos-openstack-release-{openstackversion} package.

Beginning with synergy

Make sure this module is discoverable by your Puppet instance.

Declare the synergy class (see Usage).
