• DDNS_PROVIDER: DNS provider to talk to for updating the DNS record. Required. Currently supported providers:
  • digitalocean: This provider also requires the DIGITALOCEAN_ACCESS_TOKEN variable to be set.
• DDNS_DOMAIN: The domain name to update. Required.
• DDNS_RECORD: The name of the DNS record to update. Required.
• DDNS_INTERVAL: How often the record should be checked, in seconds. Defaults to 10 minutes.
