Ansible Role for tinc VPN

This is an Ansible role for setting up one or many tinc VPN networks (https://www.tinc-vpn.org/).

Usage

Add role to your requirements.yml:

- src: https://github.com/MatthiasLohr/ansible-role-tincvpn
  name: matthiaslohr.tincvpn

It's also possible to specify the version to be installed by using the version parameters. Please read the Ansible Galaxy Documentation for details.

Set tincvpn_defaul_ip for your hosts in inventory file:

[all]
node1 tincvpn_default_ip=192.168.255.1
node2 tincvpn_default_ip=192.168.255.2
node3 tincvpn_default_ip=192.168.255.3

Simple playbook example:

- hosts: all
  roles:
    - matthiaslohr.tincvpn

For examples how to configure multiple tinc networks in parallel, take a look at the documentation.

Host Variables

Variable Name	Default Value	Description
`tincvpn_{{ tincvpn_network }}_ip`	`none`	tinc IP address of this node (should be part of `tincvpn_subnet`)

Role Variables

Configuration Tweaks

Additional Hosts

In case you want to connect to a node that is not included in the Ansible inventory (e.g. a central router you want to connect to), it is possible to configure additional hosts via playbook variables:

tincvpn_extra_hosts:
  - name: externalnode1
    address: externalnode1.example.com
    public_key: |
      -----BEGIN RSA PUBLIC KEY-----
      ...
      -----END RSA PUBLIC KEY-----

  - name: externalnode2
    address: externalnode2.example.com
    public_key: |
      -----BEGIN RSA PUBLIC KEY-----
      ...
      -----END RSA PUBLIC KEY-----

Custom Routes

tincvpn_routes:
  - network: "192.168.254.0/24"
    gateway: "192.168.255.1"
