how to set up ddns with Docker?

Pull the Docker image from skibish/ddns on Docker Hub, mount a configuration file as a volume, and run it with the -conf-file flag, as detailed in the installation section of the README.

does ddns work with IPv6?

Yes, ddns supports IPv6 by setting the ipv6 parameter to true in the configuration file, though it's disabled by default and requires enabling manually.

what notification options does ddns have?

ddns supports notifications via Gotify, SMTP email, and Telegram bots, all configurable in the YAML file with specific tokens and settings for each method.

ddns vs No-IP which is better for personal use?

ddns is free and self-hosted but requires Digital Ocean and manual setup, while No-IP offers paid convenience with less control; choose ddns for cost savings and full autonomy if you're comfortable with configuration.

how to point my domain to Digital Ocean for ddns?

Update your domain's nameservers at your registrar to Digital Ocean's NS records, then manage the domain in DO's networking panel, as referenced in the README with a link to Digital Ocean's tutorial.

What is DDNS?

DDNS is a personal Dynamic DNS client that automatically updates DNS records when your IP address changes, using Digital Ocean Networking DNS as its backend. It provides a free, self-hosted alternative to commercial DDNS services, allowing remote access to computers and servers without relying on third-party providers.

Target Audience

Individuals or developers who self-host services on computers with dynamic IP addresses and use Digital Ocean for DNS management. It's suitable for those wanting full control over their dynamic DNS without recurring fees.

Value Proposition

Developers choose this for a free, self-controlled DDNS solution that leverages Digital Ocean's existing DNS infrastructure, avoiding vendor lock-in and subscription costs of services like DynDNS or No-IP. It offers customization through Go templates and multiple notification options.

Pros & Cons

Pros

Digital Ocean Integration

Directly leverages Digital Ocean's reliable and free DNS API, providing a stable backend without subscription fees, as highlighted in the motivation section.

Template Configuration

Uses Go templates for dynamic DNS records, allowing custom data like IP addresses in TXT records, as shown in the configuration example with {{.IP}}.

Flexible Notifications

Supports multiple alert methods including Gotify, SMTP email, and Telegram, ensuring users stay informed of updates without relying on a single platform.

Docker Deployment

Available as a Docker container for easy integration into containerized environments, simplifying management and scalability.

Cons

Vendor Lock-in

Exclusively tied to Digital Ocean's DNS, so users cannot switch to other providers like Cloudflare or AWS without adopting a different solution.

Manual Setup Complexity

Requires configuring domains to point to Digital Ocean nameservers and editing YAML files, which can be error-prone and time-consuming for beginners.

Limited Real-time Updates

Default IP check period is 5 minutes, which may not be fast enough for applications requiring immediate DNS changes upon IP address shifts.

Open Source Alternative To

DDNS is an open-source alternative to the following products:

D

DynDNS

A dynamic DNS service that allows users to assign a fixed hostname to a dynamic IP address, commonly used for home networks and servers.

N

No-IP

No-IP is a dynamic DNS service that provides domain names and DNS management, allowing users to assign a hostname to a dynamic IP address for remote access to devices.
