Using DDNS-Updater for several domains I’ve setup with nginx-proxy-manager. My public IP address rarely changes, and I don’t have any mission-critical applications so i don’t need frequent updates - once daily would be enough. Despite setting the update interval in ddns-updater to 5m, 1h, 25h, etc, it continues to make DNS requests every 10 seconds. That’s over 51k per day! These go to a pi-hole so I can see them in the query log, but if I was using an external DNS, I would never know.
Correct me if I’m wrong, but it looks like ddns-updater checks all the domains each time Docker runs a “healthcheck”, but I can find nowhere to adjust the interval of the healthcheck. I assume Truenas is setup to run healthcheck on all apps every 10s and this is not user-configurable.
Right now I am periodically running the app manually and shutting it down after a few minutes. Does anyone know a way to adjust the healthcheck interval on just the ddns-updater app? Or automate starting and stopping the app as a workaround?
