Dynamic DNS Updater Docker¶

Official Image: https://hub.docker.com/r/linuxserver/duckdns
Custom Github Page: https://github.com/vttc08/docker-duckdns-dynu

This is a docker container that automatically updates the public IPv4 address of the server every 5 minutes to dynamic DNS services Dynu and DuckDNS. It is the fork of Linuxserver DuckDNS container.

Docker Compose¶

  services:
      duckdns:
        image: vttc08/docker-duckdns-dynu:latest
        container_name: duckdns
        env_file: ddns.env
        environment:

          - TZ=America/Vancouver
          - PUID=1000
          - PGID=1001
        restart: unless-stopped

These need to be filled in the ddns.env

DYNU_HOST= # full name of dynu domains
DYNU_PASS= # md5 hashed dynu login pass
SUBDOMAINS= # DuckDNS domains without the duckdns.org part
TOKEN= # DuckDNS token

token will be visible in DuckDNS dashboard
Dynu pass is the same as login; alternatively, it is possible to create a dedicated password just for IP update
MD5 generator
```
echo -n "password" | md5sum
```
when setting the IP to 10.0.0.0 in Dynu update API, dynu will automatically update the IP address to the IP address making that request

Other Usage¶

docker restart duckdns will manually run IP update
docker exec -it duckdns /app/debug.sh or other scripts, debug script will print out IP address of subdomains resolved by Cloudflare
