In this how-to I'll show how to build Debian and Ubuntu ISO images with Packer.
Packer is a tool for creating server images for platforms such as Amazon AWS, OpenStack, VMware, VirtualBox, Docker, and more — all from a single source configuration.
Here I go through the following steps:
I did it in these 5 steps:
I'll setup a 3 node Ganeti cluster on Hetzners root servers, to run static and Drupal based sites for friends and NGOs. Ganeti is designed to facilitate cluster management of virtual servers (the "instances") using commodity hardware (the "nodes"). It provides fast and simple recovery after physical failures, disk creation management, operating system installation, startup, shutdown, and failover between physical systems.
In the second part of the series I'm going to setup routed networking on a root server of Hetzner, for KVM based virtualization and with Ubuntu 12.04 LTS guests. These guests will be webservers and database-servers, connected by private LAN with internal bridge NAT-ed to eth0 of the host. Shorewall and Fail2ban will help to get the proper networking in place, next to security. Finally, a Pound load balancer (reverse proxy) with one additional public IP, will be setup, as well.
In this article I document how I installed Proxmox VE on Hetzners root server. Proxmox Virtualisation Environment is an free, open source virtualization platform, supporting OpenVZ and KVM, high availability clusters, storage and networking model, web interface for management, and has a fine graded user authentication system.
