wan-ip-monitor

A tool for homelabbers to act as a "half-measure" for dynamic DNS. It will check your WAN IP address and email you if it changes.

Setup

• Set all of the environment variables
• Run the docker image locally, or
• Run the docker compose stack (recommended).

Notes

• You can mount /ip.txt somewhere to use it outside of this program. The IP is printed to this file in plain text without a trailing newline.
• The initial run will trigger an email notification.
• You must mount /ip.txt to avoid an "initial notification" when updating/redeploying the service.
