Forgejo serve itself without a reverse proxy with HTTP and HTTPS.

HTTP transport is used by default, to turn on HTTPS transport set in `SERVER` section of the configuration `PROTOCOL=https` and either set `CERT_FILE` and `KEY_FILE` or let Forgejo manage the certificates with `ENABLE_ACME=true`

You may wish to place your Forgejo instance behind a reverse proxy. A reverse proxy is a server that accepts requests from the outside and routes them to internal services, like Forgejo.

## nginx

### Basic HTTP

To set up a basic HTTP reverse proxy in nginx, create a file `forgejo.conf` in `/etc/nginx/conf.d` and add the following configuration:

```nginx
server {
    listen 80; # Listen on IPv4 port 80
    listen [::]:80; # Listen on IPv6 port 80

    server_name git.example.com; # Change this to the server domain name.

    location / {
        proxy_pass http://127.0.0.1:3000; # Port 3000 is the default Forgejo port

        proxy_set_header Connection $http_connection;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Host $host;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header X-Forwarded-Proto $scheme;

        client_max_body_size 512M;
    }
}
```

Make sure to reload/restart nginx after changing the configuration.

### HTTP with a subpath

If you want to serve Forgejo on a subpath, e.g. on `http://example.com/forgejo`, use the following configuration:

```nginx
server {
    listen 80; # Listen on IPv4 port 80
    listen [::]:80; # Listen on IPv6 port 80

    server_name example.com; # Change this to the server domain name.

    location /forgejo/ { # Replace forgejo here with your subpath
        rewrite ^ $request_uri;
        rewrite ^/forgejo(/.*) $1 break;
        return 400;
        proxy_pass http://127.0.0.1:3000$uri;

        proxy_set_header Connection $http_connection;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Host $host;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header X-Forwarded-Proto $scheme;

        client_max_body_size 512M;
    }
}
```

Make sure to set the Forgejo `ROOT_URL` configuration key to the URL _with_ the subpath, otherwise links generated by Forgejo will be broken.

### HTTPS

When using a reverse proxy, it's usually easier to let the proxy handle HTTPS. It's easy to set up HTTPS on nginx.

#### HTTPS with Certbot

To set up HTTPS with Certbot, first set up an HTTP reverse proxy with the configuration above and ensure that it works as expected. To use HTTPS you need to have a domain name.

Then, install [certbot](https://certbot.eff.org/). When running certbot, select the domain name that your Forgejo instance is hosted under, and choose automatic installation. This should automatically set up HTTPS on port 443 and a redirect on the old port 80.

You may wish to change the `ROOT_URL` configuration key to the HTTPS protocol so links generated by Forgejo automatically use HTTPS.

#### HTTPS with manually installed certificates

If you have obtained certificates from elsewhere or have chosen not to let certbot automatically install them, make the following changes to the configuration file:

**Change the listening ports**

Change the lines

```nginx
listen 80;
listen [::]:80;
```

to

```nginx
listen 443 ssl http2;
listen [::]:443 ssl http2;
```

**Add the SSL certificate information**

Generate an SSL configuration at [mozilla](https://ssl-config.mozilla.org/#server=nginx), and add the SSL parameters to your configuration file. Make sure to replace the paths in the example with paths to your certificate files.

**Add a redirect from HTTP**

Outside the server block, add this redirection block:

```nginx
server {
    listen 80 default_server;
    listen [::]:80 default_server;

    location / {
        return 301 https://$host$request_uri;
    }
}
```

This will redirect anyone visiting the HTTP site to the HTTPS site.

## Apache

### Basic HTTP

To set up a basic HTTP proxy in Apache, create a file `100-forgejo.conf` in `/etc/apache2/sites-available` and add the following configuration:

```apache
<VirtualHost *:80>
    ServerName git.example.com

    ProxyPreserveHost On
    ProxyRequests off
    AllowEncodedSlashes NoDecode
    ProxyPass / http://127.0.0.1:3000/ nocanon
</VirtualHost>
```

Next, enable the site with `a2ensite 100-forgejo.conf` and enable the proxy modules with `a2enmod proxy proxy_http`. Finally, restart the apache server.

### HTTP with a subpath

If you want to serve Forgejo on a subpath, e.g. on `http://example.com/forgejo`, use the following configuration:

```apache
<VirtualHost *:80>
    ServerName example.com

    ProxyPreserveHost On
    ProxyRequests off
    AllowEncodedSlashes NoDecode
    ProxyPass /forgejo http://127.0.0.1:3000/ nocanon # Change /forgejo here to your desired subpath.
</VirtualHost>
```

Make sure to set the Forgejo `ROOT_URL` configuration key to the URL _with_ the subpath, otherwise links generated by Forgejo will be broken.

### HTTPS

When using a reverse proxy, it's usually easier to let the proxy handle HTTPS. It's easy to set up HTTPS on apache.

#### HTTPS with Certbot

To set up HTTPS with Certbot, first set up an HTTP reverse proxy with the configuration above and ensure that it works as expected. To use HTTPS you need to have a domain name.

Then, install [certbot](https://certbot.eff.org/). When running certbot, select the domain name that your Forgejo instance is hosted under, and choose automatic installation. This should automatically set up HTTPS on port 443 and a redirect on the old port 80.

You may wish to change the `ROOT_URL` configuration key to the HTTPS protocol so links generated by Forgejo automatically use HTTPS.

#### HTTPS with manually installed certificates

If you have obtained certificates from elsewhere or have chosen not to let certbot automatically install them, make the following changes to the configuration file:

**Change the listening ports**

Change `<VirtualHost *:80>` to `<VirtualHost *:443>`.

**Add the SSL certificate information**

Generate an SSL configuration at [mozilla](https://ssl-config.mozilla.org/#server=apache), and add the SSL parameters to your configuration file. Make sure to replace the paths in the example with paths to your certificate files.

**Add a redirect from HTTP**

Outside the `VirtualHost *:443`, add this configuration:

```apache
<VirtualHost *:80>
    ServerName git.example.com

    RewriteEngine on
    RewriteCond %{SERVER_NAME} =git.example.com
    RewriteRule ^ https://%{SERVER_NAME}%{REQUEST_URI} [END,NE,R=permanent]
</VirtualHost>
```

This will redirect anyone visiting the HTTP site to the HTTPS site.

## Caddy

### HTTPS

To set up basic HTTPS proxy in Caddy with Caddyfile create a file `forgejo` in `/etc/caddy/conf.d` and add the following configuration:

```Caddyfile
git.example.com {
  reverse_proxy 127.0.0.1:3000
}
```

Caddy will automatically get certificates for the domain.

### HTTPS with a subpath

If you want to serve Forgejo on a subpath, e.g. on https://example.com/forgejo, use the following configuration:

```Caddyfile
example.com {
  reverse_proxy /forgejo* 127.0.0.1:3000
}
```

Make sure to set the Forgejo ROOT_URL configuration key to the URL with the subpath, otherwise links generated by Forgejo will be broken.

## Proxy Authentication

Forgejo supports Reverse Proxy Header authentication, it will read headers as a trusted login user name or user email address. This hasn't been enabled by default, you can enable it with

```ini
[service]
ENABLE_REVERSE_PROXY_AUTHENTICATION = true
```

The default login user name is in the `X-WEBAUTH-USER` header, you can change it via changing `[security].REVERSE_PROXY_AUTHENTICATION_USER` in app.ini. If the user doesn't exist, you can enable automatic registration with `ENABLE_REVERSE_PROXY_AUTO_REGISTRATION=true`.

The default login user email is `X-WEBAUTH-EMAIL`, you can change it via changing `[security].REVERSE_PROXY_AUTHENTICATION_EMAIL` in app.ini, this could also be disabled with `ENABLE_REVERSE_PROXY_EMAIL`

If set `ENABLE_REVERSE_PROXY_FULL_NAME=true`, a user full name expected in `X-WEBAUTH-FULLNAME` will be assigned to the user when auto creating the user. You can also change the header name with `[security].REVERSE_PROXY_AUTHENTICATION_FULL_NAME`.

You can also limit the reverse proxy's IP address range with `[security].REVERSE_PROXY_TRUSTED_PROXIES` which default value is `127.0.0.0/8,::1/128`. By `[security].REVERSE_PROXY_LIMIT`, you can limit trusted proxies level.

Notice: Reverse Proxy Auth doesn't support the API. You still need an access token or basic auth to make API requests.

## Docker / Container Registry

The container registry uses a fixed sub-path `/v2` which can't be changed.
Even if you deploy Forgejo with a different sub-path, `/v2` will be used by the `docker` client.
Therefore you may need to add an additional route to your reverse proxy configuration.
