Building and Running

1. Build the Docker image:

   docker-compose build

2. Run the monitor as a service:

   docker-compose up -d

3. View live logs:

   docker-compose logs -f

4. Access the Real-Time Web Dashboard:

Open your browser and visit:

http://localhost:8080

This dashboard shows the current status of all monitored URLs with color-coded indicators and auto-refresh every 5 seconds.

Persistent Logs

Logs are written to uptime_monitor/logs/uptime_monitor.log
They are mapped to your host machine and persist after container restarts.

---

Reloading Configuration

After changing config.yaml, restart the container to apply changes:

docker restart uptime-monitor

---

Stopping the Service

docker-compose down
