# System Overview — bee
|
|
|
|
## What it does
|
|
|
|
Hardware audit LiveCD. Boots on a server via BMC virtual media or USB.
|
|
Collects hardware inventory at OS level (not through BMC/Redfish).
|
|
Produces `HardwareIngestRequest` JSON compatible with core/reanimator.
|
|
|
|
## Why it exists
|
|
|
|
Fills gaps where Redfish/logpile is blind:
|
|
- NVMe serials and SMART data
|
|
- DIMM serials and slot layout
|
|
- GPU serials and VBIOS versions
|
|
- Physical disks behind RAID controllers
|
|
- Full SMART wear telemetry
|
|
- NIC firmware versions
|
|
|
|
## In scope
|
|
|
|
- Read-only hardware inventory: board, CPU, memory, storage, PCIe, PSU, GPU, NIC, RAID
|
|
- Unattended operation — no user interaction required
|
|
- NVIDIA proprietary driver loaded at boot for GPU enrichment via `nvidia-smi`
|
|
- SSH access (OpenSSH) always available for inspection and debugging
|
|
- Interactive Go TUI via `bee tui` for network setup, service management, and acceptance tests
|
|
|
|
## Network isolation — CRITICAL
|
|
|
|
**The live CD runs in an isolated network segment with no internet access.**
|
|
|
|
- All tools, drivers, and binaries MUST be pre-baked into the ISO at build time
|
|
- No package installation at boot — packages are installed during ISO creation, not at runtime
|
|
- No downloads at boot — NVIDIA modules, vendor tools, and all binaries come from the ISO overlay
|
|
- DHCP is used only for LAN access (SSH from operator laptop); internet is NOT assumed
|
|
- Any feature requiring network downloads cannot be added to the live CD
|
|
|
|
## Out of scope
|
|
|
|
- Any writes to the server being audited
|
|
- Network configuration changes (persistent)
|
|
- BMC/IPMI configuration
|
|
- Anything requiring persistent storage on the audited machine
|
|
- Windows support
|
|
- Any functionality requiring internet access at boot
|
|
|
|
## Tech stack
|
|
|
|
| Component | Technology |
|
|
|---|---|
|
|
| Audit binary | Go, static, `CGO_ENABLED=0` |
|
|
| Live ISO | Debian 12 (bookworm), amd64 live-build image |
|
|
| ISO build | Debian `live-build` + overlay sync into `config/includes.chroot/` |
|
|
| Init system | `systemd` |
|
|
| SSH | OpenSSH server |
|
|
| NVIDIA driver | Proprietary `.run` installer, built against Debian kernel headers |
|
|
| NVIDIA modules | Loaded via `insmod` from `/usr/local/lib/nvidia/` |
|
|
| Builder | Debian 12 host/VM or Debian 12 container image |
|
|
|
|
## Runtime split
|
|
|
|
- The main Go application must run both on a normal Linux host and inside the live ISO
|
|
- Live-ISO-only responsibilities stay in `iso/` integration code
|
|
- Live ISO launches the Go CLI with `--runtime livecd`
|
|
- Local/manual runs use `--runtime auto` or `--runtime local`
|
|
|
|
## Key paths
|
|
|
|
| Path | Purpose |
|
|
|---|---|
|
|
| `audit/cmd/bee/` | Main CLI entry point |
|
|
| `audit/internal/collector/` | Per-subsystem collectors |
|
|
| `audit/internal/schema/` | HardwareIngestRequest types |
|
|
| `iso/builder/` | ISO build scripts and `live-build` profile |
|
|
| `iso/overlay/` | Source overlay copied into a staged build overlay |
|
|
| `iso/vendor/` | Optional pre-built vendor binaries (storcli64, sas2ircu, sas3ircu, mstflint, …) |
|
|
| `iso/builder/VERSIONS` | Pinned versions: Debian, Go, NVIDIA driver, kernel ABI |
|
|
| `iso/builder/smoketest.sh` | Post-boot smoke test — run via SSH to verify live ISO |
|
|
| `dist/` | Build outputs (gitignored) |
|
|
| `iso/out/` | Downloaded ISO files (gitignored) |
