Implementation Summary - Multi-Platform Security & Hybrid Scanning¶

Changes Made¶

This document summarizes the comprehensive updates to enable multi-platform security scanning, hybrid scan strategies, and automated release management.

✅ Completed Tasks¶

1. Dockerfile Fix (Issue #1)¶

File: Dockerfile (line 26)

Problem: ARM/v7 builds failing due to grep -v returning exit code 1 when no matches found.

Solution: Replaced grep with sed which always returns exit code 0.

Change:

# Before:
RUN grep -v "pytest\|mypy\|black\|ruff" requirements.txt > requirements.prod.txt && \
    pip install --no-cache-dir --upgrade pip && \
    pip install --no-cache-dir -r requirements.prod.txt

# After:
RUN pip install --no-cache-dir --upgrade pip && \
    sed -E '/^(pytest|mypy|black|ruff)/d' requirements.txt > requirements.prod.txt && \
    pip install --no-cache-dir -r requirements.prod.txt

Tested: ✅ Built successfully with Podman on linux/amd64

2. Multi-Platform Security Scanning (Issue #2)¶

File: .github/workflows/docker-publish.yml (complete rewrite)

Implementation: Added comprehensive 3-job workflow with matrix strategy for all platforms.

New Workflow Architecture:¶

Job 1: determine-strategy
  ├─ Detects SOLVE-IT version automatically
  ├─ Determines scan mode (quick vs full)
  └─ Outputs platform matrix

Job 2: security-scan (matrix)
  ├─ Builds: linux/amd64, linux/arm64, linux/arm/v7
  ├─ Scans each with Trivy
  └─ Uploads SARIF reports per platform

Job 3: build-and-push
  ├─ Builds multi-arch manifest
  ├─ Runs smoke tests
  ├─ Pushes to Docker Hub
  └─ Creates GitHub Release (if tag)

3. Hybrid Scanning Strategy¶

Quick Scan (AMD64 only, ~10 min) triggers on: - Draft PRs - PRs labeled "WIP"

Full Scan (3 platforms, ~22 min) triggers on: - Push to main branch - Any git tag (v*, including pre-releases) - PR marked "Ready for review" - PR labeled "security" - Manual workflow dispatch

4. Automated SOLVE-IT Version Detection¶

Method: 3-tier detection strategy

1. Check for VERSION file in SOLVE-IT repository
2. Fall back to latest git tag
3. Fall back to commit date (0.YYYY-MM format)
4. Default: 0.2025-10 with warning

Usage: Version automatically embedded in release notes and Docker tags.

5. Version Numbering Scheme¶

Format: v{SOLVEIT_VERSION}-{MAJOR}.{MINOR}.{PATCH}[-{PRERELEASE}]

Examples:

v0.2025-10-0.1.0        # Standard release
v0.2025-10-0.1.1        # Patch
v0.2025-10-0.2.0        # Minor update
v0.2025-11-0.2.0        # SOLVE-IT data update
v0.2025-11-1.0.0        # Major version
v0.2025-10-0.1.0-rc.1   # Release candidate

Docker Tags (available on both registries): - 3soos3/solve-it-mcp:v0.2025-10-0.1.0 (Docker Hub - For general users) - 3soos3/solve-it-mcp:latest (Docker Hub - For general users) - 3soos3/solve-it-mcp:stable (manual only) - ghcr.io/3soos3/solve-it-mcp:latest (GHCR - For CI/CD & compliance)

Registry Strategy: - Docker Hub: Primary for external users (tracks real adoption metrics) - GHCR: Primary for CI/CD workflows and forensic compliance

6. Automated GitHub Release Creation¶

Trigger: Any git tag matching v*

Auto-populates: - Release notes with version info - Docker pull commands - Multi-arch support details - Security scan confirmation - SOLVE-IT version - Installation instructions

Pre-release Detection: Automatically marks releases with -rc, -beta, or -alpha as pre-releases.

7. Security Configuration¶

Trivy Scanning: - Severity: CRITICAL, HIGH - Exit Code: 1 (blocks build on vulnerabilities) - Platforms: All 3 (amd64, arm64, arm/v7) - Reports: SARIF uploaded to GitHub Security tab per platform - Caching: Platform-specific caching for faster rebuilds

SARIF Upload: - Uses CodeQL v4 (v3 deprecated) - Separate category per platform for detailed tracking - Always uploads even if scan fails

📁 Files Modified¶

Total: 5 files, ~960 lines added/modified

🔍 Testing Checklist¶

Before Creating PR:¶

• Dockerfile builds on linux/amd64 with Podman
• Workflow YAML syntax is valid
• Test draft PR (should trigger quick scan)
• Test ready PR (should trigger full scan)
• Verify security label triggers full scan
• Test workflow_dispatch with full_scan=true

After Merging PR:¶

• Verify push to main triggers full scan
• Verify images pushed to Docker Hub with :stable tag
• Check GitHub Security tab for SARIF reports

For First Release:¶

• Create tag: v0.2025-10-0.1.0
• Verify full scan (3 platforms)
• Verify GitHub Release auto-created
• Verify Docker tags created correctly
• Verify multi-arch manifest includes all 3 platforms
• Test pulling and running image on each platform

📊 Expected Workflow Behavior¶

Draft PR:¶

determine-strategy: quick mode → ["linux/amd64"]
security-scan (linux/amd64): ~5 min
build-and-push: ~10 min (no push on PR)

Total: ~15 minutes

Ready for Review PR:¶

determine-strategy: full mode → ["linux/amd64","linux/arm64","linux/arm/v7"]
security-scan (3 platforms in parallel): ~12 min
build-and-push: ~10 min (no push on PR)

Total: ~22 minutes

Push to Main:¶

determine-strategy: full mode
security-scan (3 platforms): ~12 min
build-and-push: ~12 min (includes push to Docker Hub)

Total: ~24 minutes

Release Tag:¶

determine-strategy: full mode + SOLVE-IT version detection
security-scan (3 platforms): ~12 min
build-and-push: ~12 min (includes push + GitHub Release)

Total: ~24 minutes
