This directory contains a sample config that shows you how to use the [nginx](https://nginx.org/) webserver to front the integrated [Traefik](https://traefik.io/) reverse-proxy webserver with another reverse-proxy.
To get started, first follow the [front the integrated reverse-proxy webserver with another reverse-proxy](../../../docs/configuring-playbook-own-webserver.md#fronting-the-integrated-reverse-proxy-webserver-with-another-reverse-proxy) instructions and update your playbook's configuration (`inventory/host_vars/matrix.<your-domain>/vars.yml`).
Copy the [matrix.conf](matrix.conf) file to your nginx server's filesystem, modify it to your needs and include it in your nginx configuration (e.g. `include /path/to/matrix.conf;`).
This configuration **disables SSL certificate retrieval**, so you will **need to obtain SSL certificates manually** (e.g. by using [certbot](https://certbot.eff.org/)) and set the appropriate path in `matrix.conf`. In the example nginx configuration, a single certificate is used for all subdomains (`matrix.DOMAIN`, `element.DOMAIN`, etc.). For your setup, may wish to change this and use separate `server` blocks and separate certificate files for each host.
Also note that your copy of the `matrix.conf` file has to be adapted to whatever services you are using. For example, remove `element.domain.com` from the `server_name` list if you don't use [Element](../../../docs/configuring-playbook-client-element.md) web client or add `dimension.domain.com` to it if you do use the [Dimension](../../../docs/configuring-playbook-dimension.md) integration manager.
Similar to standard nginx, [Nginx Proxy Manager](https://nginxproxymanager.com/) provides nginx capabilities but inside a pre-built Docker container. With the ability for managing proxy hosts and automatic SSL certificates via a simple web interface.
If Matrix federation is enabled, then you will need to make changes to [NPM's Docker configuration](https://nginxproxymanager.com/guide/#quick-setup). By default NPM has access to ports 443, 80 and 81, but you would also need to **provide access to the fedderation ports**`8448` and `8449`.
### Creating proxy hosts in Nginx Proxy Manager
Open the 'Proxy Hosts' page in the NPM web interface and select `Add Proxy Host`, the first being for matrix web traffic. Apply the proxys configuration like this:
```md
# Details
# Matrix web proxy config
Domain Names: matrix.DOMAIN
Scheme: http
Forward Hostname/IP: IP-ADDRESS-OF-YOUR-MATRIX
Forward Port: 81
# Custom locations
# Add one custom location
Define location: /
Scheme: http
Forward Hostname/IP: IP-ADDRESS-OF-YOUR-MATRIX
Forward Port: 81
Custom config:
proxy_set_header X-Forwarded-For $remote_addr;
proxy_set_header X-Forwarded-Proto $scheme;
proxy_set_header X-Real-IP $remote_addr;
client_max_body_size 50M;
# SSL
# Either 'Request a new certificate' or select an existing one
SSL Certificate: matrix.DOMAIN or *.DOMAIN
Force SSL: true
HTTP/2 Support: true
```
Again, under the 'Proxy Hosts' page select `Add Proxy Host`, this time for your federation traffic. Apply the proxys configuration like this:
```md
# Details
# Matrix Federation proxy config
Domain Names: matrix.DOMAIN:8448
Scheme: http
Forward Hostname/IP: IP-ADDRESS-OF-YOUR-MATRIX
Forward Port: 8449
# Custom locations
# Add one custom location
Define location: /
Scheme: http
Forward Hostname/IP: IP-ADDRESS-OF-YOUR-MATRIX
Forward Port: 8449
Custom config:
proxy_set_header X-Forwarded-For $remote_addr;
proxy_set_header X-Forwarded-Proto $scheme;
client_max_body_size 50M;
# SSL
# Either 'Request a new certificate' or select an existing one
Also note, NPM would need to be configured for whatever other services you are using. For example, you would need to create additional proxy hosts for `element.DOMAIN` or `jitsi.DOMAIN`, which would use the forwarding port `81`.
