Hey fellow self-hosters! I wanted to share a tool I created to simplify DNS management when running Docker services.

What it does: Simply add labels to your Docker containers/services, and it automatically creates/updates the corresponding DNS records in Cloudflare. No more manual DNS management!

Key features:

• Works with both standalone Docker and Swarm mode
• Supports A, AAAA, CNAME, MX, and TXT records
• Automatic public IP detection
• Smart defaults (just specify the hostname, it handles the rest)
• Cloudflare proxy support
• Multiple domains/subdomains per container

Quick example:

version: "3.8"
services:
  nextcloud:
    image: nextcloud
    labels:
      - "dns.cloudflare.hostname=cloud.yourdomain.com"
      # That's it! It will automatically create an A record

More complex example:

services:
  webapp:
    image: nginx
    labels:
      - "dns.cloudflare.hostname=app.domain.com"
      - "dns.cloudflare.type=A"
      - "dns.cloudflare.proxied=true"

      # API subdomain (A record with custom TTL)
      - "dns.cloudflare.hostname.api=api.domain.com"
      - "dns.cloudflare.type.api=A"
      - "dns.cloudflare.ttl.api=3600"

      # Admin subdomain (CNAME record)
      - "dns.cloudflare.hostname.admin=admin.domain.com"
      - "dns.cloudflare.type.admin=CNAME"
      - "dns.cloudflare.content.admin=app.domain.com"

      # WWW subdomain (proxied CNAME)
      - "dns.cloudflare.hostname.www=www.domain.com"
      - "dns.cloudflare.type.www=CNAME"
      - "dns.cloudflare.content.www=app.domain.com"
      - "dns.cloudflare.proxied.www=true"

This will create:

• An A record for app.domain.com with your public IP
• An A record for api.domain.com with a 1-hour TTL
• A CNAME record for admin.domain.com pointing to app.domain.com
• A proxied CNAME for www.domain.com pointing to app.domain.com

It's open source, written in TypeScript, and designed to be lightweight and reliable. Perfect for homelab setups where you're frequently spinning up new services and need DNS to just work.
