[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 |
|
|
|
|
## Application Setup
|
|
|
|
Edit the `ddclient.conf` file found in your `/config` volume (also see official [ddclient documentation](https://ddclient.net)). 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
|
|
|
|
Here are some example snippets to help you get started creating a container from this image.
|
|
|
|
### 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
|
|
|
|
```bash
|
|
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`)
|
|
|
|
| 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. |
|
|
|
|
## Environment variables from files (Docker secrets)
|
|
|
|
You can set any environment variable from a file by using a special prepend `FILE__`.
|
|
|
|
As an example:
|
|
|
|
```bash
|
|
-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:
|
|
|
|
```bash
|
|
$ id username
|
|
uid=1000(dockeruser) gid=1000(dockergroup) groups=1000(dockergroup)
|
|
```
|
