DevConf 2017

This presentation is about a tool for the deployment of virtual machine using orchestration and configuration management to install virtual machines on physical machine, the cloud or any other provider of bare metal machines. The tool uses existing programs such as Ansible and LibVirt to interact with the hypervisor to create the virtual machines. A generic example will be explained, using libvirt, with KVM as the hypervisor, to demonstrate how easy it is to deploy virtual machines from a text file definition, which can even be generated by a machine. The presentation will explain how the tool works and how easy it is to configure the tool to your specific server/datacenter/cloud. It then demonstrates the method of creating an example, within a few steps and how it builds up a complete army of machines. The possible integration with user authentication, monitoring (Icinga/Nagios/Zabbix) and pipeline tools (Foreman) can be extended and will be explained by means of example.
