# Parallel Projects

## Overview

This directory contains the **three foundational tools** that make up Debian's complete bootc ecosystem. These tools are being developed **in parallel** rather than sequentially, following the strategy outlined in the [developmental roadmap](../developmental-roadmap.md).

## The Three Tools

### **1. deb-bootc-compose** (Main Project)
- **Location**: `../` (root of the repository)
- **Purpose**: Main orchestrator for Debian bootc image creation
- **Role**: Coordinates the entire compose process (like Pungi)
- **Status**: Foundation development (Phase 1)

### **2. deb-orchestrator** (Koji Equivalent)
- **Location**: `deb-orchestrator/`
- **Purpose**: Distributed build orchestration system
- **Role**: Manages package building at scale (like Koji)
- **Status**: Foundation development (Phase 1)

### **3. deb-mock** (Mock Equivalent)
- **Location**: `deb-mock/`
- **Purpose**: Chroot build environment manager
- **Role**: Creates isolated build environments (like Mock)
- **Status**: Foundation development (Phase 1)

## Why Parallel Development?

### **The Problem with Sequential Development**
If we built these tools one by one:
1. **deb-compose** would be built first (6 months)
2. **deb-orchestrator** would be built second (6 months)
3. **deb-mock** would be built third (6 months)
4. **Integration** would happen last (6 months)
5. **Total time**: 24 months

### **The Solution: Parallel Development**
By building all three tools simultaneously:
1. **All three tools** developed in parallel (6 months)
2. **Integration** happens during development (6 months)
3. **Production features** added (4 months)
4. **Ecosystem expansion** (2 months)
5. **Total time**: 18 months

### **Benefits of Parallel Development**
- **Faster delivery**: Complete ecosystem in 18 months vs 24 months
- **Better integration**: Tools designed to work together from the start
- **Reduced risk**: Integration issues discovered early
- **Team efficiency**: Developers can work on different tools simultaneously

## Development Strategy

### **Phase 1: Foundation Development (Months 1-6)**
All three tools developed simultaneously to basic functionality:
- **deb-bootc-compose**: Basic orchestration framework
- **deb-orchestrator**: Basic task management and build coordination
- **deb-mock**: Basic chroot management and package installation

### **Phase 2: Integration & Enhancement (Months 7-10)**
Focus on making tools work together:
- **Tool integration**: REST APIs, shared configuration, state management
- **Advanced features**: Plugin systems, caching, performance optimization
- **Testing**: Integration testing, end-to-end workflows

### **Phase 3: Production Readiness (Months 11-14)**
Make tools production-ready:
- **Security hardening**: Authentication, authorization, audit logging
- **Monitoring**: Performance metrics, alerting, observability
- **Documentation**: User guides, API documentation, deployment guides

### **Phase 4: Ecosystem Expansion (Months 15-18)**
Build actual Debian bootc variants:
- **Debian Atomic**: Base bootc images for Debian
- **Particle-OS**: Custom Debian bootc variants
- **Community tools**: Tools for creating custom variants

## Current Status

### **Week 1-8 Goals**
- [ ] **deb-bootc-compose**: Basic compose engine working
- [ ] **deb-orchestrator**: Basic task management working
- [ ] **deb-mock**: Basic chroot management working
- [ ] **Integration**: Basic communication between tools

### **Week 9-12 Goals**
- [ ] **End-to-end workflow**: Can create minimal Debian bootc images
- [ ] **Basic integration**: Tools can coordinate basic operations
- [ ] **Error handling**: Basic error handling across tool boundaries

## Development Workflow

### **Daily Development**
1. **Morning standup**: Coordinate across all three tools
2. **Development**: Work on assigned tool(s)
3. **Integration testing**: Test tool interactions
4. **Evening sync**: Share progress and blockers

### **Weekly Milestones**
1. **Monday**: Plan week's work across all tools
2. **Wednesday**: Mid-week integration testing
3. **Friday**: Review progress and plan next week

### **Integration Testing**
- **Continuous integration**: Automated testing of tool interactions
- **End-to-end testing**: Complete workflow testing
- **Performance testing**: Tool interaction performance
- **Error scenario testing**: Failure handling across tools

## Team Structure

### **Core Development Team**
- **3-4 developers**: Core tool development
- **1 developer**: Integration and testing
- **1 developer**: Documentation and user experience

### **Skill Distribution**
- **Go programming**: deb-bootc-compose, deb-orchestrator
- **Python programming**: deb-mock
- **OSTree and containers**: All tools
- **Debian tooling**: All tools
- **Integration expertise**: Cross-cutting concern

## Getting Started

### **For New Developers**
1. **Choose a tool**: Pick one of the three tools to focus on
2. **Set up environment**: Follow the tool's setup instructions
3. **Understand integration**: Learn how your tool fits with the others
4. **Start contributing**: Begin with basic functionality

### **For Integration Work**
1. **Understand all tools**: Learn the basics of all three tools
2. **Focus on APIs**: Design clean interfaces between tools
3. **Test interactions**: Ensure tools work together smoothly
4. **Document workflows**: Document how tools coordinate

## Communication

### **Cross-Tool Coordination**
- **Daily standups**: Coordinate across all tools
- **Integration meetings**: Focus on tool interactions
- **Architecture reviews**: Ensure tools work together
- **Blockers**: Identify and resolve cross-tool issues

### **Documentation**
- **Individual tool docs**: Each tool has its own documentation
- **Integration docs**: How tools work together
- **Workflow docs**: End-to-end processes
- **API docs**: Tool-to-tool communication

## Success Metrics

### **Phase 1 Success**
- All three tools have basic functionality
- Basic integration between tools working
- Can create minimal Debian bootc images
- Development team is productive and coordinated

### **Phase 2 Success**
- Tools work seamlessly together
- Performance meets basic requirements
- Advanced features are functional
- Integration is robust and reliable

### **Phase 3 Success**
- Tools are production-ready
- Security audit passed
- Performance meets production requirements
- Community integration is successful

### **Phase 4 Success**
- Debian Atomic images are production-ready
- Particle-OS variants are functional
- Advanced use cases are supported
- Ecosystem is self-sustaining

## Conclusion

This parallel development approach allows us to build Debian's complete bootc ecosystem faster and more efficiently than a sequential approach. By developing all three tools simultaneously and focusing on integration from the beginning, we can deliver a complete, working system in 18 months instead of 24 months.

The key to success is **coordination and communication** across all three tools. Each developer needs to understand not just their own tool, but how it fits into the larger ecosystem.
