Traefik2

Traefik 2.x is a reverse proxy supported by Authelia.

Configuration

Below you will find commented examples of the following configuration:

  • Traefik 2.x
  • Authelia portal
  • Protected endpoint (Nextcloud)

The below configuration looks to provide examples of running Traefik 2.x with labels to protect your endpoint (Nextcloud in this case).

Please ensure that you also setup the respective ACME configuration for your Traefik setup as this is not covered in the example below.

FAQ

Middleware authelia@docker not found

If Traefik and Authelia are defined in different docker compose stacks you may experience an issue where Traefik complains that: middleware authelia@docker not found.

This can be avoided a couple different ways:

  1. Ensure Authelia container is up before Traefik is started:
  2. Define the Authelia middleware on your Traefik container
