The article guides readers through setting up an SMS notification system using Python, Kubernetes, and Twilio to track Starlink satellites passing overhead. The script uses the Skyfield library to compute satellite positions and find upcoming sightings within a given time window. If there are any predicted sightings, Twilio sends an SMS alert to a personal phone number with the details. The script is deployed as a Docker image and pushed to Docker Hub, and then scheduled using a Kubernetes CronJob on KubeSail. The CronJob can be updated to run at specific times or with adjusted sensitivity settings, allowing users to experiment with different tracking scenarios.
