VyOS

Vyos configuration using Ansible

The goal is to create configurations for VyOS devices and applying them using Ansible. I have used Vyos as my home router, VPN endpoint device (with 1300+ ipsec tunnels) as well as a datacenter router connected to the AMS-IX using 10Gbps uplinks.

Prerequisites

Make sure you have a Vyos installation (can be virtual, can be a box, can even be a Unify Edgerouter) with ssh enabled.

Inventory file

[vyos]
10.0.1.1 ansible_user=ansible-adm ansible_network_os=vyos

Sample Playbook

---

- name: VYOS | Config eth1
  hosts: vyos
  connection: network_cli
  tasks:
    - name: VYOS | BACKUP
      vyos_config:
      backup: yes
    - name: VYOS | Apply eth1 config
      vyos_l3_interface:
        name: eth1
        ipv4: 10.0.2.1/24
        state: present

Run ansible playbook:

$ ansible-playbook -i hosts vyos.yml --ask-pass
SSH password:

Configure DNS server on VyOS

      domain_name: my.vyos.test
