Docker container to update OpenDNS IP address for networks that have a dynamic IP address
Full Description


This is a simple Docker container for updating OpenDNS IP address. This container packs the ddclient application to accomplish this. When using OpenDNS, the purpose of dynamic DNS is to preserve your OpenDNS preferences if your ISP or network operator changes your IP address. The software client keeps your IP up to date with OpenDNS automatically.


Lets Create the data-only container to initialize the /config volume

docker run --name=opendns-data \
-v /config sebestyen/docker-open-dns-ip-updater \
echo "openDNS data container"

Now lets run openDNS updater and attach to the data only container:

docker run --name=opendns -d \
-v /etc/localtime:/etc/localtime \
-v /config \
--volumes-from=opendns-data \

When run for the first time, a file named ddclient.conf will be created in the config dir, and the container will exit. Edit
this file, adding your username (email), password, and domains. Then rerun the command. You can re-start the existing container by running docker start opendns

You can edit the config file in the /config volume by mounting it and running our container in interactive mode

docker run --name=opendns-editor -it \
-v /config \
--volumes-from=opendns-data \
sebestyen/docker-open-dns-ip-updater vi /config/ddclient.conf

To check the status, run docker logs opendns.
