# stella CLI - Overview and Quick Start

**Sprint:** SPRINT_4100_0006_0006 - CLI Documentation Overhaul

## Overview

`stella` is the unified command-line interface for StellaOps, a self-hostable, sovereign container-security platform. It provides vulnerability scanning, SBOM generation, cryptographic signing, policy management, and platform administration capabilities.

**Key Features:**
- **Vulnerability Scanning**: Container image scanning with VEX-first decisioning
- **SBOM Generation**: SPDX 3.0.1 and CycloneDX 1.6 support
- **Cryptographic Compliance**: Regional crypto support (GOST, eIDAS, SM algorithms)
- **Platform Administration**: User, policy, and feed management
- **Offline-first**: Air-gapped operation support
- **Multi-tenant**: Tenant isolation and RBAC

stella auth whoami
```

#### 3. Run Your First Scan

```bash
# Scan a container image
stella scan docker://nginx:latest --output scan-result.json

# View SBOM
stella scan docker://nginx:latest --sbom-only --format spdx --output nginx.spdx.json

## Common Workflows

### 1. Daily Vulnerability Scan

```bash
#!/bin/bash
# daily-scan.sh - Run daily vulnerability scan

IMAGE="myapp:latest"
OUTPUT_DIR="scan-results/$(date +%Y-%m-%d)"

mkdir -p "$OUTPUT_DIR"

stella scan "docker://$IMAGE" \
  --sbom-format spdx \
  --attestation \
  --vex-mode strict \
  --output "$OUTPUT_DIR/scan-result.json"

# Generate HTML report
stella report \
  --scan "$OUTPUT_DIR/scan-result.json" \
  --format html \
  --output "$OUTPUT_DIR/report.html"

echo "Scan complete: $OUTPUT_DIR"
```

### 2. Compliance Attestation Workflow

```bash
#!/bin/bash
# compliance-workflow.sh - Generate compliance attestation

IMAGE="myapp:v1.2.3"

# 1. Scan image
stella scan "docker://$IMAGE" --output scan.json

# 2. Generate SBOM
stella scan "docker://$IMAGE" --sbom-only --format spdx --output sbom.spdx.json

# 3. Generate attestation
stella aoc --scan scan.json --sbom sbom.spdx.json --output attestation.jsonl

# 4. Sign attestation (GOST example for Russia)
stella crypto sign \
  --provider gost \
  --key-id compliance-key \
  --algorithm GOST12-256 \
  --file attestation.jsonl \
  --output attestation.jsonl.sig

# 5. Bundle everything
tar -czf myapp-v1.2.3-compliance.tar.gz \
  scan.json \
  sbom.spdx.json \
  attestation.jsonl \
  attestation.jsonl.sig

echo "Compliance bundle: myapp-v1.2.3-compliance.tar.gz"
```

### 3. Policy-based CI/CD Gate

```bash
#!/bin/bash
# ci-gate.sh - Fail CI build if policy violations found

IMAGE="$1"

stella scan "docker://$IMAGE" --output scan.json

# Check exit code
if [ $? -ne 0 ]; then
  echo "❌ Scan failed"
  exit 1
fi

# Check for policy violations
VIOLATIONS=$(jq '.policyViolations | length' scan.json)

if [ "$VIOLATIONS" -gt 0 ]; then
  echo "❌ Policy violations found: $VIOLATIONS"
  jq '.policyViolations' scan.json
  exit 1
fi

echo "✅ Image compliant with policy"
exit 0
```
