Building the SD Image

SD-card image guide

Set up a Pantry Raider appliance on a Raspberry Pi in four steps: flash a stock Raspberry Pi OS Lite card, boot, SSH in, and run one install command. The installer asks what you want (full stack, or a thin remote) and provisions only that. No files to edit on your PC, nothing to clone on your PC.

How it works

Pantry Raider runs on the official Raspberry Pi OS Lite (64-bit) image plus an on-device installer. You flash the stock OS, boot it, then run the installer over SSH. It detects the board, any attached display, and any attached Stream Deck, asks for the deployment mode and add-ons, then installs Docker and the containers (for a full host) or just the kiosk/Stream Deck (for a thin remote).

Tradeoff: the install needs internet and takes a few minutes the first time while it pulls Docker and the container images. After that the device is self-contained and boots fast. Staying on the official base image means you keep Raspberry Pi's security updates. (Maintainer/build details: scripts/image-build/README.md.)

What you need

• A supported board: Raspberry Pi 4 or Pi 5 (ARM64) for a full host; a Pi 3 is fine for a thin remote (see "Hardware coverage" below).
• A 16 GB+ SD card (32 GB+ recommended).
• Ethernet or Wi-Fi with internet.
• Raspberry Pi Imager on your PC to flash the card.

Step 1: Flash Raspberry Pi OS Lite (64-bit)

1. Install Raspberry Pi Imager.
2. Choose Device: your Pi model. Choose OS: Raspberry Pi OS (other) → Raspberry Pi OS Lite (64-bit). Choose Storage: your card.
3. Click the gear / Edit Settings and set:
   • Hostname: foodassistant (this becomes foodassistant.local).
   • Enable SSH (use a password or your public key) — required for Step 3.
   • Wi-Fi credentials (skip if using Ethernet).
   • Locale / timezone.
4. Write the image, then eject the card.

That is the only thing you do on your PC. Everything else happens on the Pi.

Step 2: Boot the Pi

Insert the card, connect the network (Ethernet or the Wi-Fi you configured), and power on. Give it a minute to come up on the network.

Step 3: SSH in and run the installer

From your PC, SSH to the Pi using the user and hostname you set in Imager:

ssh <user>@foodassistant.local

If foodassistant.local doesn't resolve, use the Pi's IP address (find it in your router, or it may print on an attached screen).

Then run the installer:

curl -fsSL https://raw.githubusercontent.com/Syracuse3DPrintingOrg/PantryRaider/main/install.sh | bash

The installer shows what it detected (board, display, Stream Deck) and asks one question:

• Deployment mode
  • Pi Hosted — run the full Pantry Raider stack on this Pi (Pantry Raider + Grocy). Pick this for a normal appliance.
  • Pi Remote — thin client. Installs no Docker, Grocy, or Mealie; this device only drives a kiosk and/or Stream Deck pointed at a Pantry Raider server already running elsewhere on your LAN. Viable on a Pi 3. It asks for that server's URL.

The kiosk browser and Stream Deck controller are auto-enabled when the hardware is detected at install time, and Mealie (recipes, meal plans, shopping lists) installs by default on a hosted device (set ENABLE_MEALIE=false to skip it). Everything else (Ollama, display rotation, AI provider, password, Grocy key) is configured in the browser after the install completes.

When it finishes, the terminal prints the URL to open in your browser.

Non-interactive / scripted installs

The installer can run unattended by passing the choices as environment variables and setting NONINTERACTIVE=1:

curl -fsSL https://raw.githubusercontent.com/Syracuse3DPrintingOrg/PantryRaider/main/install.sh \
  | NONINTERACTIVE=1 DEPLOYMENT_MODE=pi_hosted ENABLE_MEALIE=true bash

Recognized variables: DEPLOYMENT_MODE (pi_hosted | pi_remote | server), REMOTE_SERVER_URL, ENABLE_MEALIE, ENABLE_OLLAMA, ENABLE_KIOSK, ENABLE_STREAMDECK, DISPLAY_ROTATION, HOSTNAME. Anything left unset is auto-detected (kiosk/Stream Deck default to whether the hardware is attached).

Step 4: Complete setup in the browser

The installer prints the URL when it finishes. Open it:

http://foodassistant.local:9284/setup

The web wizard takes you through: deployment mode confirmation, security (set a password), hardware (display scale and rotation, Stream Deck), Grocy connection, AI provider, and optional integrations. When you click Start using Pantry Raider everything is saved and you're done.

A Pi Remote install has no local app; it drives the server URL you gave the installer.

If foodassistant.local doesn't resolve, use the device's IP: http://<device-ip>:9284/. (Some Android devices and older Windows lack mDNS; see Troubleshooting.)

Pre-built appliance image (advanced, no SSH)

If you want a flash-and-go card with no SSH step, a pre-built foodassistant-appliance-*-arm64.img.xz is published to the Releases page. It bakes the provisioner into the image so it self-installs the full Pi Hosted stack on first boot. Flash it with balenaEtcher or dd.

Limitations: Raspberry Pi Imager 2.x disables the OS customization tab (Wi-Fi, SSH, hostname) for third-party images, so with the pre-built image you configure Wi-Fi manually (drop a wpa_supplicant.conf on the boot partition) and create an empty /boot/firmware/ssh file to enable SSH. The pre-built image always installs the full host stack; to choose Pi Remote or pick add-ons, use the stock-OS + installer path above. The pre-built image takes its timezone from whatever the OS is set to and auto-detects display/Stream Deck.

Add-ons and settings

The installer auto-enables the kiosk and Stream Deck when the hardware is present. Use Settings in the web UI to adjust display settings, Stream Deck configuration, Wi-Fi, and hostname at any time.

To add optional backends to a running device:

Enable Mealie / Ollama later

cd /opt/foodassistant
docker compose --profile with-mealie up -d     # add Mealie
docker compose --profile with-ollama up -d      # add Ollama

Display rotation

Choose a rotation in the installer, or change it later without reflashing:

sudo /usr/local/bin/foodassistant-set-rotation 90 --reboot

This rotates the KMS framebuffer (boot console, splash, and kiosk). The app's Settings page also offers a CSS-only rotation for the kiosk browser (no reboot, but it does not affect the boot console).

Kiosk mode (touchscreen)

If a display is present at install time the installer offers to set up the kiosk: it installs cage + Chromium and starts foodassistant-kiosk.service, which opens the app full-screen on tty1. Manage it with:

systemctl status foodassistant-kiosk
systemctl restart foodassistant-kiosk

A display added later still lights up the kiosk after a re-run (see Troubleshooting).

Hardware coverage

Board / class	Status
Raspberry Pi 5 (ARM64)	✅ Recommended
Raspberry Pi 4B 4/8 GB (ARM64)	✅ Supported
Raspberry Pi 4B 2 GB	🟡 Grocy-only; Mealie tight
Raspberry Pi 3B+ / equivalent	✅ Pi Remote (thin client) only
Generic x86-64 Debian/Ubuntu	✅ Server mode (the installer runs the same way)
Other ARM64 Debian/Ubuntu boards	🟡 Best-effort; Docker via get.docker.com
Pi Zero 2 W	❌ Insufficient RAM

The installer runs on any Debian/Ubuntu host, not just a Pi. On a non-Pi host it selects Server mode automatically.

See supported-hardware.md for the full matrix.

Troubleshooting

foodassistant.local won't resolve. mDNS isn't universal. Use the device IP, or install Bonjour (Windows) / ensure avahi-daemon is running on the device (systemctl status avahi-daemon). Find the IP from your router.

The install seems stuck. It's pulling Docker images: give it 5–10 minutes on a slow connection. The provisioner logs to /var/log/foodassistant-firstboot.log (tail -f it in another SSH session).

Re-run the installer / change choices. Just run the curl ... | bash line again. To force the provisioner to redo a completed step set FORCE=1:

sudo rm -f /var/lib/foodassistant/firstboot.done
curl -fsSL https://raw.githubusercontent.com/Syracuse3DPrintingOrg/PantryRaider/main/install.sh | bash

Verify the stack.

cd /opt/foodassistant && docker compose ps

Containers didn't start. Confirm Docker installed: docker --version && docker compose version, then re-run the installer.

No internet during install. Docker install and image pulls require it. Connect the network and re-run.

docker compose up fails with "unauthorized" or "pull access denied". The GHCR package may be private. The installer handles this automatically: when the pull fails it builds the image from the on-device checkout at /opt/foodassistant-src. That first build adds a few minutes.
