Description

Installs and configures tinc mesh vpn.
Also synchronizes keys between nodes.
Requires ansible >=2.5

Example playbook:

- name: install and configure tinc mesh VPN
  hosts: all
  any_errors_fatal: true
  roles:
    - { role: tinc, tags: tinc }

Quickstart:

in host_vars/some_server:

tinc_vpn: present
tinc_vpn_hostname: internal_some_server
tinc_vpn_ip: 10.91.91.60

In group_vars/all (or whatever group you use)

tinc_netname: my_awesome_net
tinc_vpn_interface: tinc0
tinc_vpn_netmask: 255.255.255.0
tinc_vpn_subnet_cidr_netmask: 32
tinc_tcponly: 'yes'
tinc_iffonequeue: 'yes'

If you have multiple networks in same ansible root (multiple inventories sharing same playbooks / roles) make sure to use unique tinc_netname for each unique network. This is needed for proper key syncing.

Ipify

If your server is behind NAT (not so rare case) you might need to get public ip from ipify.
In that case, default setting (ansible_default_ipv4["address"]) will return LAN ip
To use ipify for getting public IP, set

tinc_physical_ip: "{{ ipify_public_ip }}"
tinc_use_ipify: true

In host/group vars.
