+# Hecuba uptime server plan
+
+## Current State
+
+- Hecuba is a Hetzner cloud host running NixOS
+- Docker is enabled for user `username`
+- Firewall allows ports 80 and 443
+- No existing uptime monitoring
+
+## Goals
+
+Monitor docker containers on hecuba with a self-hosted uptime dashboard
+
+## Uptime Monitoring Options
+
+### Option 1: Uptime Kuma (Recommended)
+
+- Easy to use web dashboard
+- Docker-based (fits existing setup)
+- HTTP/TCP/Ping monitoring
+- Status pages
+- Notifications (email, Telegram, etc.)
+
+## Implementation Plan
+
+### Phase 1: Evaluate & Choose
+- [ ] Research uptime monitoring solutions $id{11c06cf8-bea2-4858-9c7f-a293c3e8fba5}
+- [ ] Decide on solution (Uptime Kuma likely best fit) $id{f87debaa-312e-424e-80e0-b624f0768774}
+
+### Phase 2: Docker Setup
+- [ ] Add uptime monitoring container to hecuba $id{7d8c5bf4-3d49-4f4c-87f1-1f34c5a4dbec}
+- [ ] Configure persistent storage $id{9568b276-2885-4ae7-b5ca-5a9d7efb6a69}
+- [ ] Set up reverse proxy (ports 80/443 already open) $id{c2f6ea85-f5e3-465d-95ba-62738a97da80}
+- [ ] Configure SSL certificate $id{95c257e2-931b-44da-b0b1-a3e088956800}
+
+### Phase 3: Configuration
+- [ ] Add docker containers to monitor $id{4670deda-70d2-4c37-8121-2035aa7d57fb}
+- [ ] Set up alert thresholds $id{da6acf90-0b62-4451-bb11-4f74c5c5dd27}
+- [ ] Configure notifications (email/Telegram) $id{0b188adf-9a27-4499-9a19-b1ebd081bd21}
+- [ ] Test monitoring $id{dd0df63f-5da2-4ba0-a386-45162a2bb642}
+
+### Phase 4: Maintenance
+- [ ] Add to backup routine $id{33a2c381-94cb-460e-b600-67cb503826d7}
+- [ ] Document monitoring setup $id{f3bf7b85-737f-4511-8d3e-a270044abea3}
+- [ ] Review and adjust alerts $id{32e46c53-dd9d-48a8-aef2-985ebaadd8da}
+
+## Technical Details
+
+### Storage Location
+`/var/lib/uptime-kuma` or similar persistent volume
+
+### Docker Compose Structure
+```yaml
+services:
+  uptime-kuma:
+    image: louislam/uptime-kuma:1
+    volumes:
+      - /var/lib/uptime-kuma:/app/data
+    ports:
+      - 3001:3001
+    restart: always
+```
+
+### NixOS Integration
+- Consider using `virtualisation.oci-containers` for declarative setup
+- Or keep docker-compose file (more flexible for updates)
+
+## Next Steps
+1. Pick uptime monitoring solution
+2. Decide on deployment method (NixOS declarative vs docker-compose)
+3. Implement
