Mock's success comes from its ability to create isolated, reproducible build environments while delegating actual build work to the tools within those environments. This architecture allows it to handle complex build scenarios while remaining maintainable and secure. + +The roadmap's approach of building incrementally with clear phases aligns well with Mock's proven architecture.

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. + +--- + +**Next Steps**: Choose a tool to focus on, set up your development environment, and start contributing to Debian's bootc ecosystem! diff --git a/parallel_projects/deb-mock b/parallel_projects/deb-mock new file mode 120000 index 0000000..c24abc1 --- /dev/null +++ b/parallel_projects/deb-mock @@ -0,0 +1 @@ +/opt/Projects/deb-mock \ No newline at end of file diff --git a/parallel_projects/deb-orchestrator b/parallel_projects/deb-orchestrator new file mode 120000 index 0000000..7f9d4b1 --- /dev/null +++ b/parallel_projects/deb-orchestrator @@ -0,0 +1 @@ +/opt/Projects/deb-orchestrator \ No newline at end of file diff --git a/readme.md b/readme.md new file mode 100644 index 0000000..de114a2 --- /dev/null +++ b/readme.md @@ -0,0 +1,65 @@ +# Debian Bootc Ecosystem + +## Overview + +This project creates **Debian's complete bootc ecosystem** - three foundational tools that work together to create Debian bootc images.
