DuckDNS updater

A simple DuckDNS updater meant to be run in a container. It expects the config file to be mounted to /data/config.json. Logs will be written to /data/logs.

The config file should look like this:

{
  "domains": ["yourdomain", "yourotherdomain"],
  "token": "064a0540-864c-4f0f-8bf5-23857452b0c1",
  "interval": 300,
  "log": true,
  "log_verbose": false,
}

All fields are required.

domains

A list of domains to update.

token

Your DuckDNS token.

interval

The interval in seconds between updates/checks.

log

Whether to log IP changes to /data/logs/log-{month}-{year}.log or not.
