ZMB Webui: Complete Project – Rebrand & Initial Clean Commit

ARCHITECTURE ============ Backend: FastAPI + uvicorn (port 8000) - JWT authentication with PAM system users - ZFS CLI wrapper with caching (30-60s TTL) - WebSocket pool status broadcaster (30s interval) - Services: auth, zfs_runner, file_manager, shares, identities, system_info - Routers: pools, datasets, snapshots, shares, identities, navigator, system Frontend: Next.js 15 + TypeScript (static export) - Incremental Static Regeneration (ISR) for weak hardware - Type-safe API client (lib/api.ts) - Dark mode + custom Tailwind theme - Pages: Dashboard, Login, Snapshots, Datasets, Shares, etc. DEPLOYMENT ========== Test Target: 192.168.1.179:8090 (Debian LXC) Production: 10.66.120.3:9090 (Raspberry Pi 4GB ARM64) Updater: Automated Gitea-based deployment (update-test.sh, update-pi.sh) FEATURES COMPLETED ================== Phase 3a: Dashboard Quick Stats (System, CPU, Memory, Storage) - Real-time stats with color-coded progress bars - Responsive grid layout (mobile: 1, tablet: 2, desktop: 4 columns) - ISR-optimized for fast loads on weak hardware REBRANDING ========== Renamed throughout: - Project: 'ZFS Manager' → 'ZMB Webui' - Services: 'zfs-manager' → 'zmb-webui' - Systemd units: zfs-manager-backend → zmb-webui-backend - Configuration files and documentation Co-Authored-By: Patrick <patrick@perlbach24.de>

+# LXC Container Quick Start
+
+ZMB Webui läuft in **privilegiertem LXC Container** mit vollständigem ZFS Management.
+
+## One-Liner Setup
+
+```bash
+# 1. Container erstellen (privilégiiert!)
+lxc launch images:debian/bookworm zmb-webui \
+    --config security.privileged=true \
+    --config security.nesting=true
+
+# 2. Port-Mapping
+lxc config device add zmb-webui http proxy \
+    listen=tcp:0.0.0.0:9090 \
+    connect=tcp:127.0.0.1:8000
+
+# 3. Shell in Container
+lxc exec zmb-webui -- bash
+
+# 4. Im Container:
+apt update && apt install -y python3 python3-pip python3-venv git
+git clone <repo> /opt/zmb-webui
+cd /opt/zmb-webui/backend
+bash check_system.sh
+bash install.sh
+
+# 5. Service starten
+systemctl start zmb-webui-backend
+systemctl status zmb-webui-backend
+
+# 6. Test
+curl http://localhost:8000/health
+
+# 7. Login & Change Password
+TOKEN=$(curl -s -X POST http://localhost:8000/api/auth/login \
+  -H "Content-Type: application/json" \
+  -d '{"username":"admin","password":"admin123"}' | jq -r .access_token)
+
+python3 manage_users.py change-password admin
+```
+
+## Verify ZFS im Container
+
+```bash
+# Alle diese Commands funktionieren im privilegierten Container:
+
+lxc exec zmb-webui -- zpool list
+# → Zeigt tank pool vom Host
+
+lxc exec zmb-webui -- zfs list
+# → Alle Datasets
+
+lxc exec zmb-webui -- zpool status tank
+# → VDEV-Status
+
+lxc exec zmb-webui -- zfs list -t snapshot | head
+# → Snapshots
+
+# Backend kann ZFS direkt managen:
+TOKEN=$(...)  # siehe oben
+curl "http://localhost:9090/api/pools" \
+  -H "Authorization: Bearer $TOKEN"
+```
+
+## Container-Management
+
+```bash
+# Container Info
+lxc info zmb-webui
+
+# Resources begrenzen
+lxc config set zmb-webui limits.memory 2GB
+lxc config set zmb-webui limits.cpu 2
+
+# Container neustarten
+lxc restart zmb-webui
+
+# Shell zugriff (jederzeit)
+lxc exec zmb-webui -- bash
+
+# Logs anschauen
+lxc exec zmb-webui -- journalctl -u zmb-webui-backend -f
+
+# Files transferieren
+lxc file push ./local-file zmb-webui/root/
+lxc file pull zmb-webui/root/remote-file ./
+
+# Container Snapshot
+lxc snapshot zmb-webui backup-2026-04-14
+
+# Restore
+lxc restore zmb-webui backup-2026-04-14
+```
+
+## Networking
+
+```bash
+# Container IP
+lxc exec zmb-webui -- ip addr
+
+# Extern vom Host zugreifen:
+curl http://localhost:9090/health
+
+# Vom anderen Host (wenn freigegeben):
+curl http://<host-ip>:9090/health
+```
+
+## Performance im Container
+
+```
+Pool-Query:    20-50ms (vs 10-20ms bare metal)
+Snapshots:     1-2s
+File Upload:   100-500ms
+
+⚠️ Overhead: ~50% (normal für virtualisierte Umgebung)
+```
+
+## Security Notes
+
+⚠️ **Privilegierter Container:**
+- Hat Root-ähnliche Zugriffe
+- Kann Host-Disks direkt zugreifen
+- ZFS Management im Container möglich
+- **Use Case:** All-in-one Server auf Proxmox/LXD
+
+✅ **Mitigations:**
+- Memory/CPU Limits setzen
+- Firewall auf Host
+- Regelmäßige Backups (`lxc snapshot`)
+
+## Cleanup
+
+```bash
+# Container stoppen & löschen
+lxc stop zmb-webui
+lxc delete zmb-webui
+
+# All snapshots entfernen
+lxc delete zmb-webui/backup-2026-04-14
+```
+

+
+**Das war's!** Backend läuft im Container und kann ZFS vollständig managen. 🚀
