ginas is a set of Ansible playbooks designed to create and maintain a datacenter based on Debian GNU/Linux operating system. It is designed to be very flexible and automatically adapt to whatever environment you throw at it - whether these are real, hardware servers, KVM / VirtualBox / VMWare virtual machines, or OpenVZ / LXC containers - ginas should manage them just as easily.

It's hard to create a screenshot of what Linux server really looks like, so instead here you can see a gallery of what Ansible roles are currently included in ginas and what's their relationship with each other. Below you can see a basic structure of the main ginas playbook (click on the image to see it in full size):
Next graph shows Ansible role dependencies, represented by dashed lines. Here you can see what roles depend on each other. Dependencies of a role are executed before that role, and certain roles can be run multiple times by Ansible:
