# Offline Update Kit (OUK) — Air‑Gap Bundle
|
||
|
||
<!--
|
||
Build‑time variable injection:
|
||
{{ quota_anon }} = 33
|
||
{{ quota_token }} = 333
|
||
{{ dotnet }} = "10 LTS"
|
||
-->
|
||
|
||
The **Offline Update Kit** packages everything Stella Ops needs to run on a
|
||
completely isolated network:
|
||
|
||
| Component | Contents |
|
||
|-----------|----------|
|
||
| **Merged vulnerability feeds** | OSV, GHSA plus optional NVD 2.0, CNNVD, CNVD, ENISA, JVN and BDU |
|
||
| **Container images** | `stella-ops`, *Zastava* sidecar (x86‑64 & arm64) |
|
||
| **Provenance** | Cosign signature, SPDX 2.3 SBOM, in‑toto SLSA attestation |
|
||
| **Delta patches** | Daily diff bundles keep size \< 350 MB |
|
||
|
||
*Scanner core:* C# 12 on **.NET {{ dotnet }}**.
|
||
*Imports are idempotent and atomic — no service downtime.*

## 1 · Download & verify
|
||
|
||
```bash
|
||
curl -LO https://get.stella-ops.org/ouk/stella-ops-offline-kit-<DATE>.tgz
|
||
curl -LO https://get.stella-ops.org/ouk/stella-ops-offline-kit-<DATE>.tgz.sig
|
||
|
||
cosign verify-blob \
|
||
--key https://stella-ops.org/keys/cosign.pub \
|
||
--signature stella-ops-offline-kit-<DATE>.tgz.sig \
|
||
stella-ops-offline-kit-<DATE>.tgz
|
||
````
|
||
|
||
Verification prints **OK** and the SHA‑256 digest; cross‑check against the
|
||
[changelog](https://git.stella-ops.org/stella-ops/offline-kit/-/releases).
|
||

|
||
|
||
## 2 · Import on the air‑gapped host
|
||
|
||
```bash
|
||
docker compose --env-file .env \
|
||
-f docker-compose.stella-ops.yml \
|
||
exec stella-ops \
|
||
stella admin import-offline-usage-kit stella-ops-offline-kit-<DATE>.tgz
|
||
```
|
||
|
||
* The CLI validates the Cosign signature **before** activation.
|
||
* Old feeds are kept until the new bundle is fully verified.
|
||
* Import time on a SATA SSD: ≈ 25 s for a 300 MB kit.

## 3 · Delta patch workflow
|
||
|
||
1. **Connected site** fetches `stella-ouk-YYYY‑MM‑DD.delta.tgz`.
|
||
2. Transfer via any medium (USB, portable disk).
|
||
3. `stella admin import-offline-usage-kit <delta>` applies only changed CVE rows & images.
|
||
|
||
Daily deltas are **< 30 MB**; weekly roll‑up produces a fresh full kit.
|
||

|
||
|
||
## 4 · Quota behaviour offline
|
||
|
||
The scanner enforces the same fair‑use limits offline:
|
||
|
||
* **Anonymous:** {{ quota\_anon }} scans per UTC day
|
||
* **Free JWT:** {{ quota\_token }} scans per UTC day
|
||
|
||
Soft reminder at 200 scans; throttle above the ceiling but **never block**.
|
||
See the detailed rules in
|
||
[`33_333_QUOTA_OVERVIEW.md`](33_333_QUOTA_OVERVIEW.md).

## 5 · Troubleshooting
|
||
|
||
| Symptom | Explanation | Fix |
|
||
| -------------------------------------- | ---------------------------------------- | ------------------------------------- |
|
||
| `could not verify SBOM hash` | Bundle corrupted in transit | Re‑download / re‑copy |
|
||
| Import hangs at `Applying feeds…` | Low disk space in `/var/lib/stella` | Free ≥ 2 GiB before retry |
|
||
| `quota exceeded` same day after import | Import resets counters at UTC 00:00 only | Wait until next UTC day or load a JWT |
