Phase 10: The Pulse (Shared Networks & Monitoring) 💓

Congratulations! You've reached the final phase. To complete your homelab, you need a way to monitor all your services and ensure they are healthy.

🕵️ Service Discovery

In Phase 9, Gitea and Postgres shared a private network. But what if we want a Monitoring Tool to talk to every service in our homelab by their name?

Objective: The Homelab Network

1. Create a global bridge network: docker network create homelab-net
2. Task: Add this network to Gitea, Jellyfin, and Pi-hole by adding an external network block to their Compose files.

📊 Uptime Kuma

Deploy the legendary Uptime Kuma to monitor your stack.

1. Objective: Expose the UI on port 3002.
2. Network: Put it on the homelab-net network.

version: '3'
services:
  uptime-kuma:
    image: louislam/uptime-kuma:latest
    container_name: uptime-kuma
    ports:
      - 3002:3001
    networks:
      - homelab-net
    volumes:
      - ./data:/app/data

networks:
  homelab-net:
    external: true

🏆 The Final Challenge:

In the Uptime Kuma dashboard:

1. Add a "Monitor" for Gitea.
2. The Multiplier: Instead of using an IP or localhost, use its internal name: http://gitea:3000.
3. Do the same for Jellyfin (http://jellyfin:8096) and your other services.
