Wireguard setup
===============
Wireguard setup role. This role extends `this codebase <https://github.com/lablabs/ansible-collection-wireguard/tree/main/roles/wireguard>`_ to my needs. It's a bit simpler and adds more idempotence, e.g. when replaying the role to add another client to the server.
Requirements
------------
This role was written for Debian (11) and requires root privileges. It also requires to have several collections installed on your ansible host you won't necessarily have depending on your Ansible installation:
- ansible.posix
- community.general (iptables_save module)
- ansible.utils (network filters)
- netaddr (python package)
