To apply the Ansible playbooks you need to install Ansible. To do this make sure you have python and virtualenv available. Void's configuration expects python from the 3.x branch on the control host. Any version of python is acceptable on the target machines, but for consistency reasons the system python is 2.7 series.

The first step is to install and check Ansible. Within the ansible/ directory run the following commands. The virtual environment must live in a subdirectory called 'venv' as this path is referenced by ansible.cfg.

$ virtualenv venv
$ source venv/bin/activate
$ pip install -r requirements.txt

Once installed, verify that you have ansible available within path:

$ ansible --version

The version should match exactly:

$ ansible --version
ansible 2.5.5
