Duck DNS is a free service which will point a DNS (sub domains of to an IP of your choice. The service is completely free, and doesn't require reactivation or forum posts to maintain its existence.


docker create \
  --name=DuckDNS \
  -e PGID=<gid> -e PUID=<uid>  \
  -e SUBDOMAINS=<subdomains> \
  -e TOKEN=<token> \


  • -e PGID for GroupID - see below for explanation
  • -e PUID for UserID - see below for explanation
  • -e SUBDOMAINS for subdomains - multiple subdomains allowed, comma separated, no spaces
  • -e TOKEN for DuckDNS token

User / Group Identifiers

Sometimes when using data volumes (-v flags) permissions issues can arise between the host OS and the container. We avoid this issue by allowing you to specify the user PUID and group PGID. Ensure the data volume directory on the host is owned by the same user you specify and it will "just work" ™.

In this instance PUID=1001 and PGID=1001. To find yours use id user as below:

  $ id <dockeruser>
    uid=1001(dockeruser) gid=1001(dockergroup) groups=1001(dockergroup)

Setting up the application

First, go to, register your subdomain and retrieve your token
Then run the docker create command above with your subdomain(s) and token
It will update your IP with the DuckDNS service every 5 minutes


  • Shell access whilst the container is running: docker exec -it DuckDNS /bin/bash
  • Upgrade to the latest version: docker restart DuckDNS
  • To monitor the logs of the container in realtime: docker logs -f DuckDNS
