Reverse Proxies

General configuration​

  1. Set [server] ROOT_URL = https://git.example.com/ in your app.ini file.
  2. Make the reverse-proxy pass https://git.example.com/foo to http://gitea:3000/foo.
  3. Make sure the reverse-proxy does not decode the URI. The request https://git.example.com/a%2Fb should be passed as http://gitea:3000/a%2Fb.
  4. Make sure Host and X-Fowarded-Proto headers are correctly passed to Gitea to make Gitea see the real URL being visited.

Use a sub-path​

Usually it's not recommended to put Gitea in a sub-path, it's not widely used and may have some issues in rare cases.

To make Gitea work with a sub-path (eg: https://common.example.com/gitea/), there are some extra requirements besides the general configuration above:

  1. Use [server] ROOT_URL = https://common.example.com/gitea/ in your app.ini file.
  2. Make the reverse-proxy pass https://common.example.com/gitea/foo to http://gitea:3000/foo.
  3. The container registry requires a fixed sub-path /v2 at the root level which must be configured:
    • Make the reverse-proxy pass https://common.example.com/v2 to http://gitea:3000/v2.
    • Make sure the URI and headers are also correctly passed (see the general configuration above).

Nginx​

If you want Nginx to serve your Gitea instance, add the following server section to the http section of nginx.conf.

Make sure client_max_body_size is large enough, otherwise there would be "413 Request Entity Too Large" error when uploading large files.

server {
    ...
    location / {
        client_max_body_size 512M;
        proxy_pass http://localhost:3000;
        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;
    }
}

Nginx with a sub-path​

In case you already have a site, and you want Gitea to share the domain name, you can setup Nginx to serve Gitea under a sub-path by adding the following server section into the http section of nginx.conf:

server {
    ...
    location ~ ^/(gitea|v2)($|/) {
        client_max_body_size 512M;

        # make nginx use unescaped URI, keep "%2F" as-is, remove the "/gitea" sub-path prefix, pass "/v2" as-is.
        rewrite ^ $request_uri;
        rewrite ^/(gitea($|/))?(.*) /$3 break;
        proxy_pass http://127.0.0.1:3000$uri;

        # other common HTTP headers, see the "Nginx" config section above
        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;
    }
}

Then you MUST set something like [server] ROOT_URL = http://git.example.com/gitea/ correctly in your configuration.

Nginx and serve static resources directly​

We can tune the performance in splitting requests into categories static and dynamic.

CSS files, JavaScript files, images and web fonts are static content. The front page, a repository view or issue list is dynamic content.

Nginx can serve static resources directly and proxy only the dynamic requests to Gitea. Nginx is optimized for serving static content, while the proxying of large responses might be the opposite of that (see https://serverfault.com/q/587386).

Download a snapshot of the Gitea source repository to /path/to/gitea/. After this, run make frontend in the repository directory to generate the static resources. We are only interested in the public/ directory for this task, so you can delete the rest. (You will need to have Node with npm and make installed to generate the static resources)

Depending on the scale of your user base, you might want to split the traffic to two distinct servers, or use a cdn for the static files.

Single node and single domain​

Set [server] STATIC_URL_PREFIX = /_/static in your configuration.

server {
    listen 80;
    server_name git.example.com;

    location /_/static/assets/ {
        alias /path/to/gitea/public/;
    }

    location / {
        proxy_pass http://localhost:3000;
    }
}

Two nodes and two domains​

Set [server] STATIC_URL_PREFIX = http://cdn.example.com/gitea in your configuration.

# application server running Gitea
server {
    listen 80;
    server_name git.example.com;

    location / {
        proxy_pass http://localhost:3000;
    }
}
# static content delivery server
server {
    listen 80;
    server_name cdn.example.com;

    location /gitea/ {
        alias /path/to/gitea/public/;
    }

    location / {
        return 404;
    }
}

Apache HTTPD​

If you want Apache HTTPD to serve your Gitea instance, you can add the following to your Apache HTTPD configuration (usually located at /etc/apache2/httpd.conf in Ubuntu):

<VirtualHost *:80>
    ...
    ProxyPreserveHost On
    ProxyRequests off
    AllowEncodedSlashes NoDecode
    ProxyPass / http://localhost:3000/ nocanon
    RequestHeader set "X-Forwarded-Proto" expr=%{REQUEST_SCHEME}
</VirtualHost>
note

The following Apache HTTPD mods must be enabled: proxy, proxy_http.

If you wish to use Let's Encrypt with webroot validation, add the line ProxyPass /.well-known ! before ProxyPass to disable proxying these requests to Gitea.

Apache HTTPD with a sub-path​

In case you already have a site, and you want Gitea to share the domain name, you can setup Apache HTTPD to serve Gitea under a sub-path by adding the following to you Apache HTTPD configuration (usually located at /etc/apache2/httpd.conf in Ubuntu):

<VirtualHost *:80>
    ...
    <Proxy *>
         Order allow,deny
         Allow from all
    </Proxy>
    AllowEncodedSlashes NoDecode
    # Note: no trailing slash after either /git or port
    ProxyPass /git http://localhost:3000 nocanon
    ProxyPreserveHost On
    RequestHeader set "X-Forwarded-Proto" expr=%{REQUEST_SCHEME}
</VirtualHost>

Then you MUST set something like [server] ROOT_URL = http://git.example.com/git/ correctly in your configuration.

note

The following Apache HTTPD mods must be enabled: proxy, proxy_http.

Caddy​

If you want Caddy to serve your Gitea instance, you can add the following server block to your Caddyfile:

git.example.com {
    reverse_proxy localhost:3000
}

Caddy with a sub-path​

In case you already have a site, and you want Gitea to share the domain name, you can setup Caddy to serve Gitea under a sub-path by adding the following to your server block in your Caddyfile:

git.example.com {
    route /git/* {
        uri strip_prefix /git
        reverse_proxy localhost:3000
    }
}

Then set [server] ROOT_URL = http://git.example.com/git/ in your configuration.

IIS​

If you wish to run Gitea with IIS. You will need to setup IIS with URL Rewrite as reverse proxy.

  1. Setup an empty website in IIS, named let's say, Gitea Proxy.
  2. Follow the first two steps in Microsoft's Technical Community Guide to Setup IIS with URL Rewrite. That is:
  • Install Application Request Routing (ARR for short) either by using the Microsoft Web Platform Installer 5.1 (WebPI) or downloading the extension from IIS.net
  • Once the module is installed in IIS, you will see a new Icon in the IIS Administration Console called URL Rewrite.
  • Open the IIS Manager Console and click on the Gitea Proxy Website from the tree view on the left. Select and double click the URL Rewrite Icon from the middle pane to load the URL Rewrite interface.
  • Choose the Add Rule action from the right pane of the management console and select the Reverse Proxy Rule from the Inbound and Outbound Rules category.
  • In the Inbound Rules section, set the server name to be the host that Gitea is running on with its port. e.g. if you are running Gitea on the localhost with port 3000, the following should work: 127.0.0.1:3000
  • Enable SSL Offloading
  • In the Outbound Rules, ensure Rewrite the domain names of the links in HTTP response is set and set the From: field as above and the To: to your external hostname, say: git.example.com
  • Now edit the web.config for your website to match the following: (changing 127.0.0.1:3000 and git.example.com as appropriate)

</configuration>

HAProxy​

If you want HAProxy to serve your Gitea instance, you can add the following to your HAProxy configuration

add an acl in the frontend section to redirect calls to gitea.example.com to the correct backend

frontend http-in
    ...
    acl acl_gitea hdr(host) -i gitea.example.com
    use_backend gitea if acl_gitea
    ...

add the previously defined backend section

backend gitea
    server localhost:3000 check

If you redirect the http content to https, the configuration work the same way, just remember that the connection between HAProxy and Gitea will be done via http so you do not have to enable https in Gitea's configuration.

HAProxy with a sub-path​

In case you already have a site, and you want Gitea to share the domain name, you can setup HAProxy to serve Gitea under a sub-path by adding the following to you HAProxy configuration:

frontend http-in
    ...
    acl acl_gitea path_beg /gitea
    use_backend gitea if acl_gitea
    ...

With that configuration http://example.com/gitea/ will redirect to your Gitea instance.

then for the backend section

backend gitea
    http-request replace-path /gitea\/?(.*) \/\1
    server localhost:3000 check

The added http-request will automatically add a trailing slash if needed and internally remove /gitea from the path to allow it to work correctly with Gitea by setting properly http://example.com/gitea as the root.

Then you MUST set something like [server] ROOT_URL = http://example.com/gitea/ correctly in your configuration.

Traefik​

If you want traefik to serve your Gitea instance, you can add the following label section to your docker-compose.yaml (Assuming the provider is docker).

gitea:
  image: docker.io/gitea/gitea
  ...
  labels:
    - "traefik.enable=true"
    - "traefik.http.routers.gitea.rule=Host(`example.com`)"
    - "traefik.http.services.gitea-websecure.loadbalancer.server.port=3000"

This config assumes that you are handling HTTPS on the traefik side and using HTTP between Gitea and traefik.

Traefik with a sub-path​

In case you already have a site, and you want Gitea to share the domain name, you can setup Traefik to serve Gitea under a sub-path by adding the following to your docker-compose.yaml (Assuming the provider is docker) :

gitea:
  image: docker.io/gitea/gitea
  ...
  labels:
    - "traefik.enable=true"
    - "traefik.http.routers.gitea.rule=Host(`example.com`) && PathPrefix(`/gitea`)"
    - "traefik.http.services.gitea-websecure.loadbalancer.server.port=3000"
    - "traefik.http.middlewares.gitea-stripprefix.stripprefix.prefixes=/gitea"
    - "traefik.http.routers.gitea.middlewares=gitea-stripprefix"

This config assumes that you are handling HTTPS on the traefik side and using HTTP between Gitea and traefik.

Then you MUST set something like [server] ROOT_URL = http://example.com/gitea/ correctly in your configuration.
