[Ddclient](https://github.com/ddclient/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](https://github.com/docker/distribution/blob/master/docs/spec/manifest-v2-2.md#manifest-list) and our announcement [here](https://blog.linuxserver.io/2019/02/21/the-lsio-pipeline-project/).
|
|
|
|
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 |
|
|
|
|
|
|
## Usage
|
|
|
|
Here are some example snippets to help you get started creating a container.
|
|
|
|
### docker-compose ([recommended](https://docs.linuxserver.io/general/docker-compose))
|
|
|
|
Compatible with docker-compose v2 schemas.
|
|
|
|
```yaml
|
|
---
|
|
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
|
|
|
|
```
|
|
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
|
|
|
|
Container 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 |
|
|
| :----: | --- |
|
|
| `-e PUID=1000` | for UserID - see below for explanation |
|
|
| `-e PGID=1000` | for GroupID - see below for explanation |
|
|
| `-e TZ=Europe/London` | Specify a timezone to use EG Europe/London. |
|
|
| `-v /config` | Where ddclient should store its config files. |
|
|
|
|
## 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](https://en.wikipedia.org/wiki/Umask) 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)
|
|
```
|
|
|
|
|
|
|
|
## 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.
|
|
|
|
|
|
## Docker Mods
|
|
[](https://mods.linuxserver.io/?mod=ddclient "view available mods for this container.") [](https://mods.linuxserver.io/?mod=universal "view available universal mods.")
|
|
|
|
We publish various [Docker Mods](https://github.com/linuxserver/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`
|
|
|
|
## Updating Info
|
|
|
|
Most of our images are static, versioned, and require an image update and container recreation to update the app inside. With some exceptions (ie. nextcloud, plex), we do not recommend or support updating apps inside the container. Please consult the [Application Setup](#application-setup) section above to see if it is recommended for the image.
|
|
|
|
Below are the instructions for updating containers:
|
|
|
|
### Via Docker Compose
|
|
* Update all images: `docker-compose pull`
|
|
* or update a single image: `docker-compose pull ddclient`
|
|
* Let compose update all containers as necessary: `docker-compose up -d`
|
|
* or update a single container: `docker-compose up -d ddclient`
|
|
* You can also remove the old dangling images: `docker image prune`
|
|
|
|
### Via Docker Run
|
|
* Update the image: `docker pull ghcr.io/linuxserver/ddclient`
|
|
* Stop the running container: `docker stop ddclient`
|
|
* Delete the container: `docker rm ddclient`
|
|
* Recreate a new container with the same docker run parameters as instructed above (if mapped correctly to a host folder, your `/config` folder and settings will be preserved)
|
|
* You can also remove the old dangling images: `docker image prune`
|
|
|
|
### Via Watchtower auto-updater (only use if you don't remember the original parameters)
|
|
* Pull the latest image at its tag and replace it with the same env variables in one run:
|
|
```
|
|
docker run --rm \
|
|
-v /var/run/docker.sock:/var/run/docker.sock \
|
|
containrrr/watchtower \
|
|
--run-once ddclient
|
|
```
|
|
* You can also remove the old dangling images: `docker image prune`
|
|
|
|
**Note:** We do not endorse the use of Watchtower as a solution to automated updates of existing Docker containers. In fact we generally discourage automated updates. However, this is a useful tool for one-time manual updates of containers where you have forgotten the original parameters. In the long term, we highly recommend using [Docker Compose](https://docs.linuxserver.io/general/docker-compose).
|
|
|
|
### Image Update Notifications - Diun (Docker Image Update Notifier)
|
|
* We recommend [Diun](https://crazymax.dev/diun/) for update notifications. Other tools that automatically update containers unattended are not recommended or supported.
|
|
|
|
## Building locally
|
|
|
|
If you want to make local modifications to these images for development purposes or just to customize the logic:
|
|
```
|
|
git clone https://github.com/linuxserver/docker-ddclient.git
|
|
cd docker-ddclient
|
|
docker build \
|
|
--no-cache \
|
|
--pull \
|
|
-t ghcr.io/linuxserver/ddclient:latest .
|
|
```
|
|
|
|
The ARM variants can be built on x86_64 hardware using `multiarch/qemu-user-static`
|
|
```
|
|
docker run --rm --privileged multiarch/qemu-user-static:register --reset
|
|
```
|
|
|
|
Once registered you can define the dockerfile to use with `-f Dockerfile.aarch64`.
