# Deploy CM4 eMMC Provisioning to a New Proxmox Instance

Step-by-step guide to deploy the provisioning service (host + LXC) on a **new** Proxmox server. For redeploy/update and troubleshooting, see [PROXMOX-LXC-DEPLOYMENT.md](PROXMOX-LXC-DEPLOYMENT.md).

---

## Prerequisites (before running the deploy script)

| Requirement | Details |
|-------------|---------|
| **Proxmox host** | A Proxmox VE node (new or existing) where you want the service. |
| **SSH as root** | You must be able to run `ssh root@YOUR_PROXMOX_HOST` with **key-based auth** (no password prompt). |
| **Proxmox storage** | At least one active storage (e.g. `local` or `local-lvm`). Check on the host: `pvesm status`. |
| **Host internet** (recommended) | Needed so the deploy script can download the Debian 12 LXC template (if missing), and install **usbboot** and **PiShrink** on the host. Without internet, deploy still runs but you must install usbboot and PiShrink manually later. |

**Optional (set before deploy):**

- `DEPLOY_ROOTFS_STORAGE=local-lvm` — Skip interactive storage choice when creating the LXC.
- `DEPLOY_LXC_ROOT_PASSWORD=yourpassword` — Set LXC root password and enable SSH.
- `DEPLOY_LXC_SSH_KEY=/path/to/pub` — Copy this key into the LXC (default: `~/.ssh/id_ed25519.pub` or `id_rsa.pub`).
- `CM4_BACKUPS_HOST_PATH=/mnt/storage/cm4-backups` — Store backups on this host path (create the directory on the host if needed).
- **Network (WAN/LAN):**  
  `DEPLOY_LXC_WAN_BRIDGE=vmbr0` (default), `DEPLOY_LXC_WAN_IP=dhcp` (default),  
  `DEPLOY_LXC_LAN_BRIDGE=vmbr1`, `DEPLOY_LXC_LAN_SUBNET=10.20.50.1/24` — To add eth1 as provisioning LAN with a custom subnet.

---

## Step 1: Run the deploy script

From your **workstation** (where the repo is cloned), run:

```bash
cd /path/to/reTerminal\ DM4

./emmc-provisioning/scripts/deploy-to-proxmox.sh root@YOUR_PROXMOX_HOST
```

Replace `YOUR_PROXMOX_HOST` with the Proxmox hostname or IP (e.g. `10.20.30.40`).

**Example with options:**

```bash
DEPLOY_ROOTFS_STORAGE=local-lvm \
DEPLOY_LXC_ROOT_PASSWORD='YourSecurePassword' \
DEPLOY_LXC_LAN_BRIDGE=vmbr1 \
DEPLOY_LXC_LAN_SUBNET=10.20.50.1/24 \
./emmc-provisioning/scripts/deploy-to-proxmox.sh root@10.20.30.40
```

- On **first run**, the script will ask you to choose LXC rootfs storage (unless `DEPLOY_ROOTFS_STORAGE` is set). It then creates the LXC, installs host scripts, udev, systemd units, and the dashboard in the LXC.
- The script prints the **LXC IP** at the end. Note it for the next steps (or get it with:  
  `ssh root@YOUR_PROXMOX_HOST "pct exec \$(pct list -no-header -output vmid,name | awk '\''\$2==\"cm4-provisioning\"{print \$1}'\'') -- hostname -I"`).

---

## Step 2: Install usbboot on the host (if host had no internet during deploy)

USB flash/backup needs **rpiboot** on the Proxmox **host**. If the deploy log said usbboot install failed or was skipped:

**From your workstation:**

```bash
scp emmc-provisioning/scripts/install-usbboot-on-host.sh root@YOUR_PROXMOX_HOST:/tmp/
ssh root@YOUR_PROXMOX_HOST "bash /tmp/install-usbboot-on-host.sh"
```

**Or on the Proxmox host** (if `/tmp/emmc-provisioning-deploy` is still there):

```bash
ssh root@YOUR_PROXMOX_HOST
bash /tmp/emmc-provisioning-deploy/scripts/install-usbboot-on-host.sh
```

---

## Step 3: Add a golden image (required for Deploy)

To **write** an image to a device (Deploy), the host must have a **golden image** at `/var/lib/cm4-provisioning/golden.img`. Backup (read from device) works without it.

**Option A — From the dashboard**

1. Open **http://<LXC-IP>:5000** (use the LXC IP from the deploy output).
2. Build a cloud-init image or upload/set an existing backup as golden (see dashboard Admin).

**Option B — Copy an image from your machine**

```bash
scp /path/to/your-golden.img root@YOUR_PROXMOX_HOST:/var/lib/cm4-provisioning/golden.img
```

---

## Step 4: (Optional) SSH into the LXC

If you set `DEPLOY_LXC_ROOT_PASSWORD` or had a default SSH key, you can already run:

```bash
ssh root@<LXC-IP>
```

Otherwise, enable root SSH and add your key:

```bash
./emmc-provisioning/scripts/setup-lxc-ssh.sh root@YOUR_PROXMOX_HOST
# Or with password: ROOT_PASSWORD='YourPassword' ./emmc-provisioning/scripts/setup-lxc-ssh.sh root@YOUR_PROXMOX_HOST ~/.ssh/id_ed25519.pub
```

---

## Step 5: (Optional) Network boot (DHCP + TFTP on eth1)

Only if you deployed with **`DEPLOY_LXC_LAN_BRIDGE`** (and optionally `DEPLOY_LXC_LAN_SUBNET`) and want to offer network boot to devices on that LAN:

```bash
./emmc-provisioning/scripts/setup-network-boot-on-lxc.sh root@<LXC-IP>
```

See [NETWORK-BOOT-LXC.md](NETWORK-BOOT-LXC.md) for details.

---

## Step 6: (Optional) Install PiShrink on the host

If the deploy log said PiShrink install failed (e.g. no internet), and you want **Shrink/Compress** in the dashboard to work:

```bash
ssh root@YOUR_PROXMOX_HOST "bash /tmp/emmc-provisioning-deploy/scripts/install-pishrink-on-host.sh"
```

Or from your machine (stream the script): use the same pattern as in [PROXMOX-LXC-DEPLOYMENT.md](PROXMOX-LXC-DEPLOYMENT.md) for `install-pishrink-on-host.sh`.

## Summary checklist

| Step | Action | Required? |
|------|--------|------------|
| 1 | Run `deploy-to-proxmox.sh root@YOUR_PROXMOX_HOST` | **Yes** |
| 2 | Install usbboot on host (if deploy couldn’t) | For USB flash/backup |
| 3 | Add `golden.img` for Deploy | For Deploy only |
| 4 | SSH to LXC (or use setup-lxc-ssh.sh) | Optional |
| 5 | Run setup-network-boot-on-lxc.sh (if using eth1 LAN) | Optional |
| 6 | Install PiShrink on host (if deploy couldn’t) | For Shrink/Compress |

**After deployment:**

- **Dashboard:** http://&lt;LXC-IP&gt;:5000  
- **Golden image path (host and LXC):** `/var/lib/cm4-provisioning/golden.img`  
- **Disable auto-flash:** `ssh root@YOUR_PROXMOX_HOST "rm /etc/cm4-provisioning/enabled"`  
- **Enable again:** `ssh root@YOUR_PROXMOX_HOST "touch /etc/cm4-provisioning/enabled"`
