📜 Installation guide

🐋 Deploy with Docker

It is recommended to use Compose as it is very convenient. The following examples show simple deployment options:

Bridge network

---

services:
  ddns:
    image: plaenkler/ddns-updater:latest
    container_name: ddns
    restart: always
    networks:
      - web
    ports:
      - 80:80
    volumes:
      - ./ddns:/app/data
    environment:
      - DDNS_INTERVAL=600
      - DDNS_TOTP=false
      - DDNS_PORT=80

networks:
  web:
    external: false

Macvlan network

      web:
        ipv4_address: 10.10.10.2
    volumes:
      - ./ddns:/app/data
    environment:
      - DDNS_INTERVAL=600
      - DDNS_TOTP=false

      parent: eth0
    ipam:
      config:
        - subnet: "10.10.10.0/24"
          ip_range: "10.10.10.0/24"
          gateway: "10.10.10.1"

Note: DDNS Updater can also be deployed behind a proxy like Traefik or NGINX.

📄 Build from source

DDNS Updater requires the following software to be installed on your system:

• Go
• CGO

Windows Service

After cloning the repository, navigate to the root of the source tree and run the following command to build the executable file:

go build -o ddns-updater.exe cmd/svc/main.go

The program can then be stored in any file path and set up as a service using the CMD:

sc create DDNS-Updater binPath=[INSTALL_DIR]\ddns-updater.exe type=share start=auto DisplayName=DDNS-Updater

Standalone application

To build the standalone application, run the following command:

go build -o ddns-updater cmd/def/main.go

⚙️ Configuration

Depending on personal preferences, there are several ways to configure DDNS Updater. Users can select from three different methods:

1. User Interface (Frontend)

The easiest way to configure DDNS Updater is to use the integrated web interface. This can be accessed via the browser at http://host-ip. Changes to the interval take effect immediately. The program must be restarted for the other settings to take effect.

2. Configuration File

A config.yaml file is provided to store all settings. In the absence of this file, the program generates one. Users have the option to directly modify settings within this file. It is important to note that changes made here will only take effect upon restarting the program. Default settings within the file are as follows:

# How often the IP address is checked in seconds
Interval: 600
# Enable TOTP authentication
TOTP: false
# Port for the web interface
Port: 80
# Custom IP resolver returns IPv4 address in plain text
Resolver: ""

3. Environment Variables

An alternative to the configuration file are environment variables. During the program start these are read they are superordinate to the configuration file.

DDNS_INTERVAL=600
DDNS_TOTP=false
DDNS_PORT=80
DDNS_RESOLVER=ipv4.example.com
