davebv/docker-gdns repository overview

⁠docker-gdns

This is a simple Docker container for updating the Google Cloud DNS record dynamically. Both IPv4 and IPv6 are supported.

⁠Usage

Run:

Original repository

sudo docker run -d \
    --name=gdns \
    -v /etc/localtime:/etc/localtime:ro \
    -v /config/dir/path:/config \
    davebv/docker-gdns

For authentication, you will need to provide the auth key file from a service account page. How to Authorizing with a service account (https://cloud.google.com/sdk/docs/authorizing⁠).

If you would like to pass it as a environment variable, include this in your docker run command:

    -e "GCLOUD_AUTH=$(cat auth.json | openssl enc -base64)"

When run for the first time, a file named gdns.conf will be created in the config dir, and the container will exit. Edit this file, adding your domain and token. Then rerun the command.

⁠IPv4/IPv6

By default only IPV4 is enabled.
