ledokun/ddclient

ddclient running on Alpine Linux, based on linuxserver/docker-ddclient, with cURL for services like deSEC.

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.

Usage

docker create \
  --name=ddclient \
  -v <path to data>:/config \
  -e PGID=<gid> -e PUID=<uid>  \
  -e TZ=<Timezone> \
  ledokun/ddclient

Parameters

The parameters are split into two halves, separated by a colon, the left hand side representing the host and the right the container side. For example with a port -p external:internal - what this shows is the port mapping from internal to external of the container. So -p 8080:80 would expose port 80 from inside the container to be accessible from the host's IP on port 8080 http://192.168.x.x:8080 would show you what's running INSIDE the container on port 80.

-v /config - Where ddclient should store its config files
-e PGID for GroupID - see below for explanation
-e PUID for UserID - see below for explanation
-e TZ - for timezone information eg Europe/London, etc

It is based on alpine linux with s6 overlay, for shell access whilst the container is running do docker exec -it ddclient /bin/bash.

User / Group Identifiers

Sometimes when using data 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 the data volume directory on the host is owned by the same user you specify and it will "just work" ™.

In this instance PUID=1001 and PGID=1001. To find yours use id user as below:

  $ id <dockeruser>
    uid=1001(dockeruser) gid=1001(dockergroup) groups=1001(dockergroup)

Setting up the application

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.

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
