This role instanciates any inventory host that ends with .lxc and sets it up for ansible: install python, add your ssh key for root.

Note that you need lxc, dsnmasq, and sudo to be properly configured. And lxc-python2 (which require lxc-dev) installed in your ansible environment. That means that you can create a container with internet access and that you can resolve it by name.lxc. One way to set this up is to use novafloss/ansible-setup

Consider this example inventory:

[flow]
flow.lxc lxc_template_options='-r wheezy'

[rabbitmq]
rabbitmq.lxc

[redis]
redis.lxc

And a playbook like that:

---

- hosts: localhost
  become: true
  become_user: root
  roles:
  - novafloss.boot-lxc

- hosts: redis
  roles:
  - geerlingguy.redis

- hosts: rabbitmq
  roles:
  - alexey.rabbitmq

First, novafloss.boot-lxc will start the containers and create them if they don't exist, then plays will be executed normally on rabbitmq and redis container hosts.
