​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.
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:
Architecture | Tag |
x86-64 | amd64-latest |
arm64 | arm64v8-latest |
armhf | arm32v7-latest |
Here are some example snippets to help you get started creating a container from this image.
Compatible with docker-compose v2 schemas.
---version: "2.1"services:ddclient:image: ghcr.io/linuxserver/ddclientcontainer_name: ddclientenvironment:- PUID=1000- PGID=1000- TZ=Europe/Londonvolumes:- <path to data>:/configrestart: unless-stopped
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
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.
Parameter | Function |
Env | Function |
| for UserID - see below for explanation |
| for GroupID - see below for explanation |
| Specify a timezone to use EG Europe/London. |
Volume | Function |
| Where ddclient should store its config files. |
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.
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.
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 usernameuid=1000(dockeruser) gid=1000(dockergroup) groups=1000(dockergroup)
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.
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.
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
