​Ddclient is a Perl client used to update dynamic DNS entries for accounts on Dynamic DNS Network Service Provider. It was originally written by Paul Burry and is now mostly by wimpunk. It has the capability to update more than just dyndns and it can fetch your WAN-ipaddress in a few different ways.

Supported Architectures

Our images support multiple architectures such as x86-64, arm64 and armhf. We utilise the docker manifest for multi-platform awareness. More information is available from docker here and our announcement here.

Simply pulling ghcr.io/linuxserver/ddclient should retrieve the correct image for your arch, but you can also pull specific arch images via tags.

The architectures supported by this image are:

Application Setup

Edit the ddclient.conf file found in your /config volume (also see official ddclient documentation). This config file has many providers to choose from and you basically just have to uncomment your provider and add username/password where requested. If you modify ddclient.conf, ddclient will automaticcaly restart and read the config.

Get dynamic IP from Fritz.Box

If ddclient shall fetch the dynamic (public) IP-address from a fritz.box (AVM) add the following line to /config/ddclient.conf:

use=cmd, cmd=/etc/ddclient/get-ip-from-fritzbox

Usage

To help you get started creating a container from this image you can either use docker-compose or the docker cli.

docker-compose (recommended, click here for more info)

---
version: "2.1"
services:
  ddclient:
    image: ghcr.io/linuxserver/ddclient
    container_name: ddclient
    environment:
      - PUID=1000
      - PGID=1000
      - TZ=Europe/London
    volumes:
      - <path to data>:/config
    restart: unless-stopped

docker cli (click here for more info)

docker run -d \
  --name=ddclient \
  -e PUID=1000 \
  -e PGID=1000 \
  -e TZ=Europe/London \
  -v <path to data>:/config \
  --restart unless-stopped \
  ghcr.io/linuxserver/ddclient

Parameters

Docker images are configured using parameters passed at runtime (such as those above). These parameters are separated by a colon and indicate <external>:<internal> respectively. For example, -p 8080:80 would expose port 80 from inside the container to be accessible from the host's IP on port 8080 outside the container.

Ports (-p)

Environment Variables (-e)

Volume Mappings (-v)

Environment variables from files (Docker secrets)

You can set any environment variable from a file by using a special prepend FILE__.

As an example:

-e FILE__PASSWORD=/run/secrets/mysecretpassword

Will set the environment variable PASSWORD based on the contents of the /run/secrets/mysecretpassword file.

Umask for running applications

For all of our images we provide the ability to override the default umask settings for services started within the containers using the optional -e UMASK=022 setting. Keep in mind umask is not chmod it subtracts from permissions based on it's value it does not add. Please read up here before asking for support.

User / Group Identifiers

When using 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 any volume directories on the host are owned by the same user you specify and any permissions issues will vanish like magic.

In this instance PUID=1000 and PGID=1000, to find yours use id user as below:

  $ id username
    uid=1000(dockeruser) gid=1000(dockergroup) groups=1000(dockergroup)

Docker Mods

​​​ ​​​

We publish various Docker Mods to enable additional functionality within the containers. The list of Mods available for this image (if any) as well as universal mods that can be applied to any one of our images can be accessed via the dynamic badges above.

Support Info

• Shell access whilst the container is running:

  • docker exec -it ddclient /bin/bash

• To monitor the logs of the container in realtime:

  • docker logs -f ddclient

• Container version number

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

• Image version number

  • docker inspect -f '{{ index .Config.Labels "build_version" }}' ghcr.io/linuxserver/ddclient
