CM4 Provisioning Dashboard

Flask web UI to monitor the eMMC deployment process and show device connection steps.

  • Connection steps: Numbered instructions for putting the reTerminal in boot mode and connecting it.
  • Live status: Idle / Connecting (rpiboot) / Flashing / Backup / Done / Error, with optional progress.
  • Backup / Restore: Toggle between Flash (deploy golden image) and Backup (save eMMC to a timestamped file when device is connected in boot mode). List and download saved backups.
  • Recent log: Tail of the flash log (from the host, via the shared bind mount).

The dashboard reads /var/lib/cm4-provisioning/status.json and flash.log, which the flash script (running on the Proxmox host) updates. When the dashboard runs inside the LXC, that directory is bind-mounted from the host, so it sees the same files.

Run locally (development)

cd dashboard
pip install flask  # or use venv
python3 app.py
# Open http://localhost:5000

Run in LXC (Proxmox)

  1. Copy the dashboard into the container (e.g. to /opt/cm4-provisioning/dashboard).
  2. Install Flask if needed: apt install -y python3-flask or pip install flask.
  3. Install the systemd unit and enable it:
cp /opt/cm4-provisioning/dashboard/cm4-dashboard.service /etc/systemd/system/
systemctl daemon-reload
systemctl enable --now cm4-dashboard
  1. Open http://<LXC-IP>:5000 (or port-forward from the Proxmox host).

Environment (optional)

  • CM4_STATUS_FILE – path to status JSON (default: /var/lib/cm4-provisioning/status.json).
  • CM4_LOG_FILE – path to flash log (default: /var/lib/cm4-provisioning/flash.log).
