# HAProxy
|
|
|
|
[HAProxy] is a reverse proxy supported by **Authelia**.
|
|
|
|
## Requirements
|
|
|
|
You need the following to run Authelia with HAProxy:
|
|
|
|
* HAProxy 1.8.4+ (2.2.0+ recommended)
|
|
* `USE_LUA=1` set at compile time
|
|
* [haproxy-lua-http](https://github.com/haproxytech/haproxy-lua-http) must be available within the Lua path
|
|
* A `json` library within the Lua path (dependency of haproxy-lua-http, usually found as OS package `lua-json`)
|
|
* With HAProxy 2.1.3+ you can use the [`lua-prepend-path`] configuration option to specify the search path.
|
|
* [haproxy-auth-request](https://github.com/TimWolla/haproxy-auth-request/blob/master/auth-request.lua)
|
|
|
|
|
|
## Configuration
|
|
|
|
Below you will find commented examples of the following configuration:
|
|
|
|
* Authelia portal
|
|
* Protected endpoint (Nextcloud)
|
|
* Protected endpoint with `Authorization` header for basic authentication (Heimdall)
|
|
* [haproxy-auth-request](https://github.com/TimWolla/haproxy-auth-request/blob/master/auth-request.lua)
|
|
|
|
With this configuration you can protect your virtual hosts with Authelia, by following the steps below:
|
|
1. Add host(s) to the `protected-frontends` or `protected-frontends-basic` ACLs to support protection with Authelia.
|
|
You can separate each subdomain with a `|` in the regex, for example:
|
|
```
|
|
acl protected-frontends hdr(host) -m reg -i ^(?i)(jenkins|nextcloud|phpmyadmin)\.example\.com
|
|
acl protected-frontends-basic hdr(host) -m reg -i ^(?i)(heimdall)\.example\.com
|
|
```
|
|
2. Add host ACL(s) in the form of `host-service`, this will be utilised to route to the correct
|
|
backend upon successful authentication, for example:
|
|
```
|
|
acl host-jenkins hdr(host) -i jenkins.example.com
|
|
acl host-nextcloud hdr(host) -i nextcloud.example.com
|
|
acl host-phpmyadmin hdr(host) -i phpmyadmin.example.com
|
|
acl host-heimdall hdr(host) -i heimdall.example.com
|
|
```
|
|
3. Add backend route for your service(s), for example:
|
|
```
|
|
use_backend be_jenkins if host-jenkins
|
|
use_backend be_nextcloud if host-nextcloud
|
|
use_backend be_phpmyadmin if host-phpmyadmin
|
|
use_backend be_heimdall if host-heimdall
|
|
```
|
|
4. Add backend definitions for your service(s), for example:
|
|
```
|
|
backend be_jenkins
|
|
server jenkins jenkins:8080
|
|
backend be_nextcloud
|
|
server nextcloud nextcloud:443 ssl verify none
|
|
backend be_phpmyadmin
|
|
server phpmyadmin phpmyadmin:80
|
|
backend be_heimdall
|
|
server heimdall heimdall:443 ssl verify none
|
|
```
|
|
|
|
### Secure Authelia with TLS
|
|
There is a [known limitation](https://github.com/TimWolla/haproxy-auth-request/issues/12) with haproxy-auth-request with regard to TLS-enabled backends.
|
|
If you want to run Authelia TLS enabled the recommended workaround utilises HAProxy itself to proxy the requests.
|
|
This comes at a cost of two additional TCP connections, but allows the full HAProxy configuration flexibility with regard
|
|
to TLS verification as well as header rewriting. An example of this configuration is also be provided below.
