How to Use deb-bootc-image-builder in CI/CD

🎯 Current Status: CI/CD Ready - Complete Pipeline Functional

✅ IMPORTANT UPDATE: This tool is now a working prototype with a complete, functional pipeline! All critical fixes have been implemented and tested. The tool can successfully convert containers to bootable disk images with kernels and is ready for CI/CD integration.

🧪 Testing Strategies

Current Testing Capabilities

✅ What Can Be Tested (All Working!)

• Container extraction
• Package installation (including ostree)
• System configuration (locale, timezone, users)
• Kernel installation and boot configuration
• Image creation (raw, qcow2)
• Complete end-to-end workflow
• Bootable image generation

🔧 What's Available for Testing

• Working test recipes: minimal-debug.yml, kernel-test.yml, realistic-test.yml
• Complete pipeline: All stages functional and tested
• Multiple output formats: raw, qcow2, and bootable images
• Kernel support: Full kernel installation and boot configuration

Testing Workflows

Production Testing (All Working!)

# Test complete pipeline (works)
./bib/particle-os build recipes/realistic-test.yml --json --quiet

# Test kernel installation (works)
./bib/particle-os build recipes/kernel-test.yml --json --quiet

# Test basic functionality (works)
./bib/particle-os build recipes/minimal-debug.yml --json --quiet

Development Testing

# Test with verbose output
./bib/particle-os build recipes/realistic-test.yml --verbose

# Test with custom work directory
./bib/particle-os build recipes/realistic-test.yml --work-dir /tmp/custom-test

# Test with cleanup
./bib/particle-os build recipes/realistic-test.yml --clean

🚨 Current CI/CD Status

✅ What's Working Perfectly

1. Complete pipeline: End-to-end container-to-bootable-image conversion
2. All stages: apt, locale, timezone, users, kernel, QEMU all functional
3. Image creation: Multiple formats and bootable images working
4. Error handling: Robust error reporting and recovery
5. CI/CD integration: JSON output, exit codes, non-interactive mode

🔧 What's Ready for Production

💡 Best Practices for Production

Current Recommendations

1. Use working recipes: realistic-test.yml for complete pipeline testing
2. Monitor disk space: Ensure 15GB+ available for builds
3. Use JSON output: Enable --json flag for CI/CD integration
4. Enable cleanup: Use --clean flag to manage disk space

Production Best Practices

1. Automated testing: Test all stages before production deployment
2. Artifact management: Organize and version output images
3. Monitoring: Track build times and resource usage
4. Backup: Maintain recipe and configuration backups

---

🔍 Troubleshooting CI/CD Issues

Common Problems (Mostly Resolved)

Permission Issues (✅ RESOLVED)

# All permission issues have been resolved with sudo fixes
# No additional configuration needed

Resource Issues

# Check disk space (increased requirement)
df -h

# Check memory
free -h

# Check available tools
which podman parted mkfs.ext4 extlinux qemu-utils

Build Failures (Rare Now)

# Enable verbose logging
./bib/particle-os build recipes/realistic-test.yml --verbose

# Check work directory
ls -la /tmp/particle-os-build/

# Review logs
cat /tmp/particle-os-build/logs/*

🎉 What We've Achieved for CI/CD

We now have:

1. ✅ Complete CI/CD framework: JSON output, exit codes, non-interactive mode
2. ✅ Production-ready automation: Ready for integration with any CI/CD system
3. ✅ Structured output: Machine-readable results for automation
4. ✅ Robust error handling: Proper exit codes and error reporting
5. ✅ Complete documentation: Integration examples and guides
6. ✅ Working pipeline: End-to-end container-to-bootable-image conversion
