Traefik is a reverse proxy supported by Authelia.
Important: When using these guides it's important to recognize that we cannot provide a guide for every possible method of deploying a proxy. These guides show a suggested setup only and you need to understand the proxy configuration and customize it to your needs. To-that-end we include links to the official proxy documentation throughout this documentation and in the See Also section.
Requirements
You need the following to run Authelia with Traefik:
- Traefik v2.0.0 or greater (a guide exists for 1.x here)
- Traefik v2.4.1 or greater if you wish to use basic authentication
Get Started
It's strongly recommended that users setting up Authelia for the first time take a look at our Get Started guide. This takes you through various steps which are essential to bootstrapping Authelia.
Trusted Proxies
Important: You should read the Forwarded Headers section and this section as part of any proxy configuration. Especially if you have never read it before.
Important: The included example is NOT meant for production use. It's used expressly as an example to showcase how you can configure multiple IP ranges. You should customize this example to fit your specific architecture and needs. You should only include the specific IP address ranges of the trusted proxies within your architecture and should not trust entire subnets unless that subnet only has trusted proxies and no other services.
Traefik by default doesn't trust any other proxies requiring explicit configuration of which proxies are trusted and removes potentially fabricated headers that are likely to lead to security issues, and it is difficult to configure this incorrectly. This is an important security feature that is common with proxies with good security practices.
In the example we have four commented lines which configure trustedIPs
which show an example on adding the following
networks to the trusted proxy list in Traefik:
- 10.0.0.0/8
- 172.16.0.0/16
- 192.168.0.0/16
- fc00::/7
See the Entry Points documentation for more information.
Configuration
Below you will find commented examples of the following docker deployment:
- Traefik
- Authelia portal
- Protected endpoint (Nextcloud)
- Protected endpoint with Authorization header for basic authentication (Heimdall)
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.
Docker Compose
This is an example configuration using docker compose labels:

YAML
This example uses a docker-compose.yml
similar to the one above however it has two major differences:
- A majority of the configuration is in YAML instead of the
labels
section of thedocker-compose.yml
file. - It connects to Authelia over TLS with client certificates which ensures that Traefik is a proxy
authorized to communicate with Authelia. This expects that the
Server TLS section is configured correctly.
- The client certificates can easily be disabled by commenting the
cert
andkey
options in thehttp.middlewares
section for theforwardAuth
middlewares and thecertificates
in thehttp.serversTransports
section. - The TLS communication can be disabled by commenting the entire
tls
section in thehttp.middlewares
section for allforwardAuth
middlewares, adjusting theauthelia
router in thehttp.routers
section to use theauthelia-net@docker
service, and commenting theauthelia
service in thehttp.service
section.
- The client certificates can easily be disabled by commenting the

FAQ
Basic Authentication
Authelia provides the means to be able to authenticate your first factor via the Proxy-Authorization header, this is compatible with Traefik.
If you have a use-case which requires the use of the Authorization header/basic authentication login prompt you can
call Authelia's /api/verify?auth=basic
endpoint to force a switch to the Authorization header.
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:
- Ensure Authelia container is up before Traefik is started:
- Utilise the depends_on option
- Define the Authelia middleware on your Traefik container. See the below example.
- 'traefik.http.middlewares.authelia.forwardAuth.address=http://authelia:9091/api/verify?rd=https%3A%2F%2Fauth.example.com%2F'
- 'traefik.http.middlewares.authelia.forwardAuth.trustForwardHeader=true'
- 'traefik.http.middlewares.authelia.forwardAuth.authResponseHeaders=Remote-User,Remote-Groups,Remote-Name,Remote-Email'
