Proxy

Apache

This guide provides a brief overview for installing Woodpecker server behind the Apache2 web-server. This is an example configuration:

ProxyPreserveHost On

RequestHeader set X-Forwarded-Proto "https"

ProxyPass / http://127.0.0.1:8000/
ProxyPassReverse / http://127.0.0.1:8000/

You must have these Apache modules installed:

• proxy
• proxy_http

You must configure Apache to set X-Forwarded-Proto when using https.

 ProxyPreserveHost On

+RequestHeader set X-Forwarded-Proto "https"

 ProxyPass / http://127.0.0.1:8000/
 ProxyPassReverse / http://127.0.0.1:8000/

Nginx

This guide provides a basic overview for installing Woodpecker server behind the Nginx web-server. For more advanced configuration options please consult the official Nginx documentation.

Example configuration:

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

    location / {
        proxy_set_header X-Forwarded-For $remote_addr;
        proxy_set_header X-Forwarded-Proto $scheme;
        proxy_set_header Host $http_host;

        proxy_pass http://127.0.0.1:8000;
        proxy_redirect off;
        proxy_http_version 1.1;
        proxy_buffering off;

        chunked_transfer_encoding off;
    }
}

You must configure the proxy to set X-Forwarded proxy headers:

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

     location / {
+        proxy_set_header X-Forwarded-For $remote_addr;
+        proxy_set_header X-Forwarded-Proto $scheme;

         proxy_pass http://127.0.0.1:8000;
         proxy_redirect off;
         proxy_http_version 1.1;
         proxy_buffering off;

         chunked_transfer_encoding off;
     }
 }

Caddy

This guide provides a brief overview for installing Woodpecker server behind the Caddy web-server. This is an example caddyfile proxy configuration:

# expose WebUI and API
woodpecker.example.com {
  reverse_proxy woodpecker-server:8000
}

# expose gRPC
woodpeckeragent.example.com {
  reverse_proxy h2c://woodpecker-server:9000
}

:::note Above configuration shows how to create reverse-proxies for web and agent communication. If your agent uses SSL do not forget to enable WOODPECKER_GRPC_SECURE. :::

Tunnelmole

Tunnelmole is an open source tunneling tool.

Start by installing tunnelmole.

After the installation, run the following command to start tunnelmole:

tmole 8000

It will start a tunnel and will give a response like this:

➜  ~ tmole 8000
http://bvdo5f-ip-49-183-170-144.tunnelmole.net is forwarding to localhost:8000
https://bvdo5f-ip-49-183-170-144.tunnelmole.net is forwarding to localhost:8000

Set WOODPECKER_HOST to the Tunnelmole URL (xxx.tunnelmole.net) and start the server.

Ngrok

Ngrok is a popular closed source tunnelling tool. After installing ngrok, open a new console and run the following command:

ngrok http 8000

Set WOODPECKER_HOST to the ngrok URL (usually xxx.ngrok.io) and start the server.

Traefik

To install the Woodpecker server behind a Traefik load balancer, you must expose both the http and the gRPC ports. Here is a comprehensive example, considering you are running Traefik with docker swarm and want to do TLS termination and automatic redirection from http to https.

version: '3.8'

services:
  server:
    image: woodpeckerci/woodpecker-server:latest
    environment:
      - WOODPECKER_OPEN=true
      - WOODPECKER_ADMIN=your_admin_user
      # other settings ...

    networks:
      - dmz # externally defined network, so that traefik can connect to the server
    volumes:
      - woodpecker-server-data:/var/lib/woodpecker/

    deploy:
      labels:
        - traefik.enable=true

volumes:
  woodpecker-server-data:
    driver: local

You should pass WOODPECKER_GRPC_SECURE=true and WOODPECKER_GRPC_VERIFY=true to your agent when using this configuration.
