lsioarmhf/duckdns repository overview

THIS IMAGE IS DEPRECATED. PLEASE USE THE MULTI-ARCH IMAGES AT linuxserver/duckdns

The LinuxServer.io⁠ team brings you another container release featuring easy user mapping and community support. Find us for support at:

• forum.linuxserver.io⁠
• IRC⁠ on freenode at #linuxserver.io
• Podcast⁠ covers everything to do with getting the most from your Linux Server plus a focus on all things Docker and containerisation!

⁠lsioarmhf/duckdns

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

⁠Usage

docker create \
  --name=duckdns \
  -e PGID=<gid> -e PUID=<uid>  \
  -e SUBDOMAINS=<subdomains> \
  -e TOKEN=<token> \
  -e TZ=<timezone> \
  lsioarmhf/duckdns

⁠Parameters

The parameters are split into two halves, separated by a colon, the left hand side representing the host and the right the container side. For example with a port -p external:internal - what this shows is the port mapping from internal to external of the container. So -p 8080:80 would expose port 80 from inside the container to be accessible from the host's IP on port 8080 http://192.168.x.x:8080 would show you what's running INSIDE the container on port 80.

• -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
• -e TZ for timezone information, eg Europe/London
• optional -e LOG_FILE=true if you prefer the duckdns log to be written to a file instead of the docker log
• optional -v <path to data>:/config used in conjunction with logging to file

⁠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

IMPORTANT... THIS IS THE ARMHF VERSION

First, go to duckdns site⁠, 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

If you'd like the output in a file, set the optional parameter LOG_FILE to true and map a volume for /config

⁠Info

• Shell access whilst the container is running: docker exec -it duckdns /bin/bash

• To monitor the logs of the container in realtime: docker logs -f duckdns

• container version number

docker inspect -f '{{ index .Config.Labels "build_version" }}' duckdns

• image version number

docker inspect -f '{{ index .Config.Labels "build_version" }}' lsioarmhf/duckdns
