= Using Ansible =

[http://www.ansible.com Ansible] is a configuration management system that does not require any special installation on the nodes besides Python and SSH. Currently most UFO software can be deployed with it.

== Installing Ansible ==

Ansible has to be installed only on the machine from which the installation should be orchestrated. The simplest way is to setup a virtual env and install Ansible from PyPI:

{{{
$ mkvirtualenv ansible
$ (workon ansible)
$ pip install ansible
}}}

== Running our playbooks ==

A machine state is configured through Ansible playbooks and roles. The UFO configuration can be cloned via

{{{
$ git clone http://ufo.kit.edu/git/playbooks
}}}

In there you find a `setup.yml` mapping hosts onto roles and giving them tags. Hosts are specified in a hosts file, one example is already present as `hosts.sample`. To run a playbook you have to specifiy the hosts file, the user (in our case root) and optionally which tag to run:

{{{
$ ansible-playbook -i hosts -u root -t compute setup.yml
}}}
