Docker Pulls Docker Stars Build Status

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 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:

Architecture Tag
x86-64 amd64-latest
arm64 arm64v8-latest
armhf arm32v6-latest

Usage

Here are some example snippets to help you get started creating a container from this image.

docker

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

docker-compose

Compatible with docker-compose v2 schemas.

---
version: "2"
services:
  ddclient:
    image: linuxserver/ddclient
    container_name: ddclient
    environment:
      - PUID=1000
      - PGID=1000
      - TZ=Europe/London
    volumes:
      - <path to data>:/config
    restart: unless-stopped

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`

Parameter Function

Environment Variables `-e`

Env Function
PUID=1000 for UserID - see below for explanation
PGID=1000 for GroupID - see below for explanation
TZ=Europe/London Specify a timezone to use EG Europe/London.

Volume Mappings `-v`

Volume Function
/config Where ddclient should store its config files.

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)

Application Setup

Edit the ddclient.conf file found in your /config volume. 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.

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" }}' linuxserver/ddclient
