Homepage: https://traefik.io
Traefik is a reverse proxy used to provide external access to your Ansible-NAS box. Additionally, Traefik will automatically request and renew SSL certificates for you.
You can configure which applications are available externally by enabling the <application_name>_available_externally setting
for each application in the Advanced Settings section of your all.yml.
See External Access for more info.
Usage
Set traefik_enabled: true in your inventories/<your_inventory>/group_vars/nas.yml file.
Traefik's web interface can be found at http://ansible_nas_host_or_ip:8083.
Specific Configuration
You'll need to map port 80 and 443 from your router to your Ansible-NAS box. A quick search should reveal instruction for your model of router.
