Envoy is 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.
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.
Configuration
Below you will find commented examples of the following configuration:
- Authelia Portal
- Protected Endpoint (Nextcloud)
Example
Support for Envoy is possible with Authelia v4.37.0 and higher via Envoy's external authorization filter.
