|
[Traefik] v1 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](#see-also) section.*
|
|
|
|
## 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
|
|
|
|
## Configuration
|
|
|
|
Below you will find commented examples of the following docker deployment:
|
|
|
|
* [Traefik] 1.x
|
|
* Authelia portal
|
|
* Protected endpoint (Nextcloud)
|
|
* Protected endpoint with `Authorization` header for basic authentication (Heimdall)
|
|
|
|
The below configuration looks to provide examples of running [Traefik] v1 with labels to protect your endpoint
|
|
(Nextcloud in this case).
|
|
|
|
Please ensure that you also setup the respective [ACME](https://docs.traefik.io/v1.7/configuration/acme/) configuration
|
|
for your [Traefik] setup as this is not covered in the example below.
|
|
|
|
### Basic Authentication
|
|
|
|
Authelia provides the means to be able to authenticate your first factor via the `Proxy-Authorization` header.
|
|
Given that this is not compatible with [Traefik] 1.x you can call the __Authelia__ `/api/verify` endpoint with the
|
|
`auth=basic` query parameter to force a switch to the `Authentication` header.
