# Current Project Status - Realistic Assessment
|
||||
|
||||
## 🎯 Project Overview
|
||||
**deb-bootc-image-builder** - A tool for building bootable Debian-based operating system images using container images as the base.
|
||||
|
||||
## 📊 Current Status: **PARTIALLY WORKING** ⚠️
|
||||
|
||||
### ✅ **What's Actually Working**
|
||||
|
||||
#### 1. Core Container Infrastructure
|
||||
- **Container extraction**: Successfully extracts `debian:trixie-slim` and other container images
|
||||
- **Filesystem handling**: Properly manages rootfs creation and cleanup
|
||||
- **Package management**: apt commands work correctly in chroot environment
|
||||
- **Permission handling**: Fixed ownership and permission issues for chroot operations
|
||||
|
||||
#### 2. Image Building Pipeline
|
||||
- **Recipe parsing**: Successfully loads and validates YAML recipes
|
||||
- **Stage execution**: apt stage works completely (package installation, updates, cleanup)
|
||||
- **Rootfs creation**: Creates functional rootfs with installed packages
|
||||
- **Basic image creation**: Can create raw disk images with proper partitioning
|
||||
|
||||
#### 3. Bootable Image Generation
|
||||
- **Disk formatting**: Creates GPT partition tables and ext4 filesystems
|
||||
- **Bootloader installation**: extlinux/syslinux installation works
|
||||
- **Bootable structure**: Images are recognized as bootable by QEMU
|
||||
- **Basic boot process**: System attempts to boot from hard disk
|
||||
|
||||
### ❌ **What's Still Broken/Incomplete**
|
||||
|
||||
#### 1. Recipe Stage Execution
|
||||
- **Locale stage**: Fails during locale generation (chroot permission issues)
|
||||
- **Timezone stage**: Untested, likely has similar issues
|
||||
- **Users stage**: Untested, may have chroot permission problems
|
||||
- **QEMU stage**: Not fully implemented
|
||||
|
||||
#### 2. Image Creation Issues
|
||||
- **Final image creation**: The `createFinalImage()` function exists but isn't reached due to stage failures
|
||||
- **Output formats**: Only raw format is tested, qcow2/vmdk/vdi untested
|
||||
- **Image validation**: No comprehensive testing of created images
|
||||
|
||||
#### 3. Bootability Limitations
|
||||
- **Kernel missing**: The `debian:trixie-slim` base doesn't include a kernel
|
||||
- **Minimal boot**: Current images boot to bootloader but lack full OS boot capability
|
||||
- **Init system**: Basic sysvinit setup, not production-ready
|
||||
|
||||
## 🔧 **Technical Debt & Issues**
|
||||
|
||||
### 1. Error Handling
|
||||
- **Truncated error messages**: Error wrapping loses important details
|
||||
- **Silent failures**: Some operations fail without clear error reporting
|
||||
- **Recovery mechanisms**: Limited ability to recover from partial failures
|
||||
|
||||
### 2. Permission Management
|
||||
- **sudo dependency**: Heavy reliance on sudo for chroot operations
|
||||
- **Permission inconsistencies**: Mixed ownership between user and root
|
||||
- **Cleanup issues**: Some temporary files and mounts may not be properly cleaned
|
||||
|
||||
### 3. Testing Coverage
|
||||
- **Limited testing**: Only tested with `debian:trixie-slim` base image
|
||||
- **No integration tests**: End-to-end workflow not fully validated
|
||||
- **QEMU testing**: Basic boot testing only, no functional validation
|
||||
|
||||
## 📈 **Progress Metrics**
|
||||
|
||||
| Component | Status | Completion |
|
||||
|-----------|--------|------------|
|
||||
| Container Extraction | ✅ Working | 95% |
|
||||
| Package Management | ✅ Working | 90% |
|
||||
| Recipe Parsing | ✅ Working | 100% |
|
||||
| Stage Execution | ⚠️ Partial | 40% |
|
||||
| Image Creation | ✅ Working | 80% |
|
||||
| Bootloader Installation | ✅ Working | 85% |
|
||||
| Bootability | ⚠️ Partial | 60% |
|
||||
| Error Handling | ❌ Poor | 20% |
|
||||
| Testing | ❌ Limited | 30% |
|
||||
|
||||
## 🎯 **Immediate Next Steps (Realistic)**
|
||||
|
||||
### 1. **Fix Remaining Stages** (High Priority)
|
||||
- Resolve locale stage chroot permission issues
|
||||
- Test and fix timezone and users stages
|
||||
- Ensure all recipe stages can complete successfully
|
||||
|
||||
### 2. **Complete Image Creation Pipeline** (High Priority)
|
||||
- Integrate working bootable image creation into main build flow
|
||||
- Test all output formats (raw, qcow2, vmdk, vdi)
|
||||
- Add proper error handling and recovery
|
||||
|
||||
### 3. **Improve Bootability** (Medium Priority)
|
||||
- Add kernel installation capability
|
||||
- Implement proper init system setup
|
||||
- Test full OS boot process
|
||||
|
||||
### 4. **Enhance Testing** (Medium Priority)
|
||||
- Add comprehensive unit tests
|
||||
- Implement integration testing
|
||||
- Add automated QEMU boot validation
|
||||
|
||||
## 🚨 **Current Limitations**
|
||||
|
||||
### 1. **Production Readiness**
|
||||
- **NOT ready for production use**
|
||||
- Limited error handling and recovery
|
||||
- No comprehensive testing
|
||||
- Bootability issues with current base images
|
||||
|
||||
### 2. **Base Image Support**
|
||||
- **Only tested with `debian:trixie-slim`**
|
||||
- No validation with other base images
|
||||
- Limited architecture support (x86_64 only)
|
||||
|
||||
### 3. **Recipe Complexity**
|
||||
- **Simple recipes work** (apt stage)
|
||||
- Complex recipes with multiple stages may fail
|
||||
- Limited stage type support
|
||||
|
||||
## 💡 **What We've Learned**
|
||||
|
||||
### 1. **Success Patterns**
|
||||
- Container extraction with proper cleanup works well
|
||||
- Package management in chroot with sudo is reliable
|
||||
- GPT partitioning and ext4 formatting is stable
|
||||
- Basic bootloader installation is functional
|
||||
|
||||
### 2. **Failure Patterns**
|
||||
- Chroot operations without proper permissions fail consistently
|
||||
- Error message truncation makes debugging difficult
|
||||
- Stage failures stop the entire build process
|
||||
- Missing kernels prevent full OS boot
|
||||
|
||||
### 3. **Architecture Insights**
|
||||
- The modular stage-based approach is sound
|
||||
- Container-to-rootfs conversion works well
|
||||
- Bootable image creation is achievable
|
||||
- Integration points need better error handling
|
||||
|
||||
## 🎉 **Achievements**
|
||||
|
||||
Despite the limitations, we have:
|
||||
|
||||
1. **Transformed a broken placeholder generator** into a functional image builder
|
||||
2. **Solved the core technical challenges** of container extraction and package management
|
||||
3. **Created a working bootable image pipeline** that produces QEMU-recognizable images
|
||||
4. **Established a solid foundation** for a production-ready OS image builder
|
||||
|
||||
## 🔮 **Realistic Timeline to Production**
|
||||
|
||||
- **Stage completion**: 1-2 weeks
|
||||
- **Full pipeline integration**: 2-3 weeks
|
||||
- **Testing and validation**: 2-4 weeks
|
||||
- **Production readiness**: 6-8 weeks total
|
||||
|
||||
## 📝 **Conclusion**
|
||||
|
||||
We've made **significant progress** on the core technical challenges and have a **working foundation** for a bootable image builder. The system can successfully extract containers, install packages, and create bootable disk images. However, there are still **important gaps** in stage execution, error handling, and testing that need to be addressed before this can be considered production-ready.
|
||||
|
||||
The project is in a **"working prototype"** state - functional enough to demonstrate the concept and build basic images, but not yet robust enough for production use.
