This role allowes you to deploy a fast, secure and provider agnostic private network between multiple servers. This is usefull for providers like hetzner cloud that do not provide you with a private network or if you want to connect servers that are spread over multiple regions and providers.
The role installs wireguard on Debian or Ubuntu, creates a mesh between all servers by adding them all as peers and configures the wg-quick systemd service.
Installation can be done using ansible galaxy:
$ ansible-galaxy install mawalu.wireguard_private_networking
Install this role, assign a vpn_ip
variable to every host that should be part of the network and run the role. Plese make sure to allow the VPN port (default is 5888) in your firewall. Here is a small example configuration:
# inventory host file
wireguard:
hosts:
1.1.1.1:
vpn_ip: 10.1.0.1/32
2.2.2.2:
vpn_ip: 10.1.0.2/32
# playbook
- name: Configure wireguard mesh
hosts: wireguard
remote_user: root

Feel free to open issues or MRs if you find problems or have ideas for improvements. I'm especially open for MRs that add support for more operating systems.
