Cloudflare DNS updater_rs

Cloudflare DNS Record updater written in rust. Manage your custom domain without static ip.

Setup

1. Install Rust (edition 2024 compatible).
2. Update .env file in the project root with your credentials:

[email protected]
CLOUDFLARE_API_KEY=your_api_key_or_token
CLOUDFLARE_DOMAIN=example.com

3. Build or run:

cargo run
# or
cargo build -r

What it does

• Loads credentials from environment variables (or .env).
• Looks up the zone and A record for CLOUDFLARE_DOMAIN via Cloudflare API.
• Fetches your current public IPv4 from https://checkip.amazonaws.com.
• Updates the A record when the IP changes (every 10 minutes by default).

Notes

• Uses curl bindings; OpenSSL is vendored by default. On Windows, ensure perl and nasm are available when building.
• Only IPv4 is supported currently.
