# P5G Marvis — Full Setup Guide

This document describes the complete architecture and deployment procedure for the
**P5G Marvis** sidebar extension that injects custom pages into the Athonet NCM UI.

---

## Deployment Model

The target environment for this project is a host where services are started by
`systemd`, including Docker-backed services. Marvis is intended to run the same
way:

- the FastAPI app runs in a container with host networking on `127.0.0.1:8100`
- Traefik exposes it at `/core/marvis/*`
- `patch-ncm.py` injects the sidebar entries and iframe routes into the NCM UI
- the injected entries should only be added for services that are actually
  reachable on the host when the patch is applied

For a containerised deployment without Compose, this repo includes an example
unit file at `config/p5g-marvis.service`.

### Build the image

```bash
docker build -t p5g-marvis:latest .
```

### Install the systemd unit

```bash
cp config/p5g-marvis.service /usr/lib/systemd/system/p5g-marvis.service
mkdir -p /etc/p5g-marvis
cp config/marvis.env.example /etc/p5g-marvis/marvis.env
systemctl daemon-reload
systemctl enable --now p5g-marvis
```

Marvis will then be reachable on:

```text
http://127.0.0.1:8100
http://127.0.0.1:8100/api/docs
```

Edit `/etc/p5g-marvis/marvis.env` per host instead of hardcoding addresses in the
unit file. In particular:

- set `MARVIS_PROMETHEUS_URL` and `MARVIS_ALERTMANAGER_URL` to the correct host
  endpoints for that appliance
- keep the defaults if Prometheus and Alertmanager are already available on host
  loopback from the appliance network namespace

---

## Deploy / Re-deploy to a Host

### Prerequisites
- SSH key: `~/.ssh/5G-SSH-Key.pem`
- Target host must have Python 3.x and the Athonet NCM stack running

### Step 1 — Copy application files

```bash
TARGET=<IP>   # e.g. 172.27.0.159 or 192.168.86.150

ssh -i ~/.ssh/5G-SSH-Key.pem root@$TARGET 'mkdir -p /opt/p5g-marvis/app/ui /opt/p5g-marvis/app/routers /opt/p5g-marvis/app/services /etc/athonet/traefik/ssl'

scp -i ~/.ssh/5G-SSH-Key.pem \
  ~/p5g-marvis/requirements.txt ~/p5g-marvis/patch-ncm.py \
  root@$TARGET:/opt/p5g-marvis/

scp -i ~/.ssh/5G-SSH-Key.pem \
  ~/p5g-marvis/app/__init__.py ~/p5g-marvis/app/main.py ~/p5g-marvis/app/config.py \
  root@$TARGET:/opt/p5g-marvis/app/

scp -i ~/.ssh/5G-SSH-Key.pem ~/p5g-marvis/app/ui/*.html \
  root@$TARGET:/opt/p5g-marvis/app/ui/

scp -i ~/.ssh/5G-SSH-Key.pem ~/p5g-marvis/app/routers/*.py \
  root@$TARGET:/opt/p5g-marvis/app/routers/

scp -i ~/.ssh/5G-SSH-Key.pem ~/p5g-marvis/app/services/*.py \
  root@$TARGET:/opt/p5g-marvis/app/services/
```

### Step 2 — Install Python dependencies

```bash
ssh -i ~/.ssh/5G-SSH-Key.pem root@$TARGET '
  python3 -m ensurepip --upgrade 2>/dev/null
  python3 -m pip install -r /opt/p5g-marvis/requirements.txt --break-system-packages -q
'
```

### Step 3 — Create systemd service

```bash
ssh -i ~/.ssh/5G-SSH-Key.pem root@$TARGET 'cat > /etc/systemd/system/p5g-marvis.service << EOF
[Unit]
Description=P5G Marvis AI Network Assistant
After=network.target

[Service]
Type=simple
WorkingDirectory=/opt/p5g-marvis
Environment=MARVIS_PROMETHEUS_URL=http://127.0.0.1:9090
Environment=MARVIS_PROMETHEUS_PREFIX=/prometheus
Environment=MARVIS_ALERTMANAGER_URL=http://127.0.0.1:9093
Environment=MARVIS_AI_MODE=openai
Environment=MARVIS_OPENAI_BASE_URL=https://172.27.0.135:8001
Environment=MARVIS_OPENAI_MODEL=gemma-4-26B-A4B-it-UD-Q4_K_S.gguf
ExecStart=/usr/bin/python3 -m uvicorn app.main:app --host 0.0.0.0 --port 8100
Restart=always
RestartSec=5

[Install]
WantedBy=multi-user.target
EOF
systemctl daemon-reload
systemctl enable p5g-marvis
systemctl start p5g-marvis'
```

### Step 4 — Create Traefik routing config

Create `/etc/athonet/traefik/ssl/marvis.yml`:

```bash
ssh -i ~/.ssh/5G-SSH-Key.pem root@$TARGET 'cat > /etc/athonet/traefik/ssl/marvis.yml << EOF
http:
  routers:
    router-marvis-0:
      rule: "PathPrefix(\`/core/marvis\`)"
      service: service-marvis
      entryPoints:
        - websecure
      tls: {}
      priority: 25
      middlewares:
        - cors@http
        - strip-path-marvis-0

    # Add router-radio-0 here if rm-ui is present (port 4000)

  middlewares:
    strip-path-marvis-0:
      stripPrefix:
        prefixes:
          - "/core/marvis"

  services:
    service-marvis:
      loadBalancer:
        servers:
          - url: "http://127.0.0.1:8100"
        passHostHeader: false
EOF'
```

### Step 5 — Add file provider to Traefik static config

Append to `/etc/athonet/traefik/traefik.yml` under the `providers:` section:

```yaml
  file:
    filename: "/etc/traefik/ssl/marvis.yml"
    watch: true
```

> **Note**: The path inside the container is `/etc/traefik/ssl/marvis.yml` because the `ssl/` directory is bind-mounted. The host path is `/etc/athonet/traefik/ssl/marvis.yml`.

```bash
ssh -i ~/.ssh/5G-SSH-Key.pem root@$TARGET '
grep -q "file:" /etc/athonet/traefik/traefik.yml || (
  echo "  file:" >> /etc/athonet/traefik/traefik.yml
  echo "    filename: \"/etc/traefik/ssl/marvis.yml\"" >> /etc/athonet/traefik/traefik.yml
  echo "    watch: true" >> /etc/athonet/traefik/traefik.yml
)
docker restart traefik'
```

### Step 6 — Patch the NCM JS bundle

```bash
ssh -i ~/.ssh/5G-SSH-Key.pem root@$TARGET '
JS="/etc/athonet/ems-frontend/advanced/assets/index-Cw8Irsq8.js"
# Only create .bak if it does not already exist (preserve the clean original)
[ -f "$JS.bak" ] || cp "$JS" "$JS.bak"
cd /opt/p5g-marvis && python3 patch-ncm.py'
```

`patch-ncm.py` injects only the services it detects as reachable on the host:

- `P5G_MARVIS_ENABLED=true|false` overrides Marvis detection
- `P5G_RADIO_ENABLED=true|false` overrides Radio detection
- by default it probes `127.0.0.1:8100` for Marvis and `127.0.0.1:4000` for Radio

Expected output:
```
Applied: sidebar entry
Applied: injected iframe routes
Applied: permissions entry
Done — P5G Marvis: 10 occurrences, P5G Radio: 3 occurrences
```

If you see `Skipped:` instead of `Applied:`, the patch was already applied from a previous run — this is safe.

### Step 7 — Verify

```bash
ssh -i ~/.ssh/5G-SSH-Key.pem root@$TARGET '
systemctl status p5g-marvis --no-pager | head -5
curl -sk http://127.0.0.1:8100/health'
```

Expected: `{"status":"ok"}`

## Update a UI Page

To update any UI page (e.g. after editing `tasks.html` locally):

```bash
/usr/bin/scp -i ~/.ssh/5G-SSH-Key.pem \
  ~/p5g-marvis/app/ui/tasks.html \
  root@<IP>:/opt/p5g-marvis/app/ui/tasks.html
```

No service restart needed — FastAPI reads the file on each request.

---

## Re-run the JS Patch (e.g. after an NCM upgrade)

If NCM is upgraded and the JS bundle is replaced:

```bash
ssh -i ~/.ssh/5G-SSH-Key.pem root@<IP> '
JS="/etc/athonet/ems-frontend/advanced/assets/index-Cw8Irsq8.js"
# The new build will have a different filename — update patch-ncm.py JS= and BAK= lines
# Then create a fresh .bak and re-run
cp "$JS" "$JS.bak"
cd /opt/p5g-marvis && python3 patch-ncm.py'
```

> **Warning**: Check if the bundle filename changed after the upgrade. The filename is `index-<hash>.js`. Update the `JS` variable at the top of `patch-ncm.py` if it has changed.

---

## What the Patch Does (patch-ncm.py)

The script modifies the minified NCM React JS bundle in 3 places — it always reads from the `.bak` (clean original) ensuring it is safe to re-run:

1. **Sidebar nav entry** — appends P5G Marvis (with 4 sub-items) and P5G Radio items to the existing top-level navigation after the UPF entry.

2. **React Router routes** — inserts `/marvis` and `/radio` route objects between the existing UPF and Platform routes. Each renders an iframe pointing to `/core/marvis/<page>` or `/core/radio/`.

3. **Permissions registry** — registers all `/marvis/*` and `/radio` paths in the BW permissions map with `Tt` (always-allowed), preventing "Permissions for route not managed" errors.

---

## Troubleshooting

| Problem | Check |
|---|---|
| Sidebar items not visible | Browser hard-refresh (Cmd+Shift+R). Confirm patch ran successfully. |
| Clicking sidebar shows blank page | Traefik routing — check `docker logs traefik`. `marvis.yml` must be present and file provider added to `traefik.yml`. |
| Service won't start | `journalctl -u p5g-marvis -n 50`. Usually a missing Python package. |
| Metrics not loading | Confirm Prometheus is on `127.0.0.1:9090` — check `MARVIS_PROMETHEUS_URL` env var in the service file. |
| patch-ncm.py: ERROR anchor not found | The NCM JS bundle was upgraded and the filename/content changed. Find new anchors in the `.bak` file and update `patch-ncm.py`. |
| After NCM upgrade patch not applied | Re-run Step 6 — but first check if the bundle filename changed. |
