| Environment variable | Function |
|---|---|
USERNAME | Mandatory. This is your dynu login username. |
PASSWORD | Mandatory. This is your dynu login password. |
HOSTNAMES | Mandatory. This are your domains that you want to update. They should be comma separated like this www.mydomain.com,www.someotherdomain.com. If you got only one, than just input that one |
DYNU_UPDATE_URL | Optional. This is the official Dynu endpoint URL http://api.dynu.com/nic/update. If it is not specified, it will default to it automatically. |
IP_SOURCES | Optional. This is an URL to API that can resolve your external IP. If it is not specified it will default to ipify.org |
REFRESH_TIME | Optional. This environment var defines the time interval (in seconds) that the dynu's API will be called. The default number is 300 (5 minutes). So every five minutes the script will be called and will ask IP update from dynu's endpoint. |
TZ | Optional. Use the proper timezone, as the script's log shows warnings (APscheduler is being used to make the interval calls) |
Additionally you can bind a port, and if you use a monitoring tool (like uptime-kuma), you can make API calls to the service using http://your_local_ip_to_server:1050/status. This endpoint will return the last responses from ipfy (IP_SOURCES) and dynu (DYNU_UPDATE_URL) - the last time that the check was ran. The response codes can be 200 for successful response from dynu, or 400 if there was any kind of error.
