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.

linuxserver/ddclient

Supported Architectures

We utilise the docker manifest for multi-platform awareness. More information is available from docker here and our announcement here.
Simply pulling lscr.io/linuxserver/ddclient:latest 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 | Available | Tag | | :----: | :----: | ---- | | x86-64 | ✅ | amd64-\ | | arm64 | ✅ | arm64v8-\ |

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 ````

Read-Only Operation

This image can be run with a read-only container filesystem. For details please read the docs.

Caveats

/tmp must also be mounted to tmpfs for this image.

Non-Root Operation

This image can be run with a non-root user. For details please read the docs.

Usage

To help you get started creating a container from this image you can either use docker-compose or the docker cli.
>!NOTE >Unless a parameter is flagged as 'optional', it is mandatory and a value must be provided.

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

---
services:
  ddclient:
    image: lscr.io/linuxserver/ddclient:latest
    container_name: ddclient
    environment:
      - PUID=1000
      - PGID=1000
      - TZ=Etc/UTC
    volumes:
      - /path/to/ddclient/config:/config
    restart: unless-stopped

docker cli (click here for more info)

docker run -d \
  --name=ddclient \
  -e PUID=1000 \
  -e PGID=1000 \
  -e TZ=Etc/UTC \
  -v /path/to/ddclient/config:/config \
  --restart unless-stopped \
  lscr.io/linuxserver/ddclient:latest

Parameters

Containers 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=Etc/UTC | specify a timezone to use, see this list. | | -v /config | Persistent config files | | --read-only=true | Run container with a read-only filesystem. Please read the docs. | | --user=1000:1000 | Run container with a non-root user. Please read the docs. |

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__MYVAR=/run/secrets/mysecretvariable

Will set the environment variable MYVAR based on the contents of the /run/secrets/mysecretvariable 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 your_user as below:

id your_user

Example output:

uid=1000(your_user) gid=1000(your_user) groups=1000(your_user)

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:

```bash
docker exec -it ddclient /bin/bash
```

To monitor the logs of the container in realtime:

```bash
docker logs -f ddclient
```

Container version number:

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

Image version number:

```bash
docker inspect -f '{{ index .Config.Labels "build_version" }}' lscr.io/linuxserver/ddclient:latest
```

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 (noted in the relevant readme.md), we do not recommend or support updating apps inside the container. Please consult the Application Setup section above to see if it is recommended for the image.
Below are the instructions for updating containers:

Via Docker Compose

Update images:

* All images:

    ```bash
    docker-compose pull
    ```

* Single image:

    ```bash
    docker-compose pull ddclient
    ```

Update containers:

* All containers:

    ```bash
    docker-compose up -d
    ```

* Single container:

    ```bash
    docker-compose up -d ddclient
    ```

You can also remove the old dangling images:

```bash
docker image prune
```

Via Docker Run

Update the image:

```bash
docker pull lscr.io/linuxserver/ddclient:latest
```

Stop the running container:

```bash
docker stop ddclient
```

Delete the container:

```bash
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:

```bash
docker image prune
```

Image Update Notifications - Diun (Docker Image Update Notifier)

>!TIP >We recommend 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 lscr.io/linuxserver/ddclient:latest .

The ARM variants can be built on x8664 hardware and vice versa using lscr.io/linuxserver/qemu-static
docker run --rm --privileged lscr.io/linuxserver/qemu-static --reset

Once registered you can define the dockerfile to use with -f Dockerfile.aarch64.

Serve Ddclient on your own domain behind Caddy, Nginx or Traefik. Fill in your domain and copy the result. It's a starting point, some apps need their own base URL or extra headers set too.

Proxy Domain App port Upstream

Proxying ddclient.example.com to http://Ddclient:80

Add this to your Caddyfile

ddclient.example.com {
	reverse_proxy http://Ddclient:80
}

Check the logs first

Nine times out of ten the logs tell you exactly what went wrong.

In Portainer, go to Containers, click the container, then Logs. Or run docker logs Ddclient
Exit codes help too: 137 means killed, usually out of memory. 126 or 127 means the command inside the image is broken.

Port already in use

If deployment fails with "Bind for 0.0.0.0:80 failed: port is already allocated", something else on your server is using that port.

Find what's using it: sudo ss -tlnp | grep :80
Stop the other service, or pick a different host port. In 80:80 only the left number is yours to change, the right one belongs to the app.

Running but the page won't load

The container is up but nothing appears in your browser.

Use your server's real IP: http://your-server-ip:80. The 0.0.0.0 link Portainer shows isn't a real address.
Give it a minute after first deploy, Ddclient can take a while to initialise.
Make sure your firewall allows the port, e.g. sudo ufw allow 80

Permission denied on volumes

If the logs show "permission denied", the app can't write to its data folder on the host.

Fix the ownership: sudo chown -R 1000:1000 /srv/lsio/ddclient/config
Or set the PUID and PGID variables (defaults 1000:1000) to match your own user, found with id $USER

Image won't pull

Test the pull directly on the host: docker pull linuxserver/ddclient:latest

"manifest unknown" means the tag no longer exists. This template uses latest, so try pinning a specific version instead.
"toomanyrequests" is the Docker Hub rate limit. Log in with docker login to raise it.
"no space left on device" means a full disk. Reclaim space with docker system prune

"exec format error"

This means the image was built for a different CPU architecture than your server.

This image supports: amd64, arm64
Check yours with uname -m: x86_64 is amd64, aarch64 is arm64. Raspberry Pi and other ARM boards are the usual culprits.

Container keeps restarting

The unless-stopped restart policy relaunches the app after every crash, so the real error can scroll past.

Check the logs right after a restart, the last few lines before it died are the useful ones.
Get the exit code with docker inspect Ddclient --format '{{.State.ExitCode}}'
Still stuck? Redeploy once with the restart policy set to no so the failure stays visible.
