ansible-playbook bite.yml

Creating a new container:

• Add an entry in host_vars/bite/lxc.yml.
• Run ansible-playbook bite.yml. This will create the container. It will also install all superuser's keys under /root/.ssh/authorized_keys.
• Create the Ansible play for the machine. Include the lxc-guest role. On the first run, use ansible-playbook $host.yml -e ansible_user=root.
