Introduction

This article describes the simplest way to quickly get started with Cloudflare DDNS.

Prerequisites

1. Register a Cloudflare Account

We won’t go into detail here; please refer to other tutorials.

2. Get a Cloudflare API Token

1. Visit https://dash.cloudflare.com/profile/api-tokens
2. Click “Create Token” and select the “Edit zone DNS” template
3. Enter any name
4. Set permissions to edit zone DNS:
   • Zone - Zone - Read
   • Zone - DNS - Edit
5. For Zone Resources, select the domain for DDNS
6. Client IP Filter (optional) — leave blank since DDNS uses dynamic IPs
7. TTL — leave empty

Background

• We need an analytics tool to track static website visits.
• Many users install uBlock, AdBlock, etc., causing many analytics services to miss traffic.

Plausible

Plausible is an open-source analytics tool for tracking static website visits. Its highlights:

• Open source under AGPLv3
• No cookies, no user tracking, no personal data collection
• Small script size, does not affect page load speed
• Supports public statistics
• Supports email subscription for stats

This article uses docker-compose to deploy Plausible with the official Docker image, excluding email-related components.

Prerequisites

• CMake
• Linux
