Next Steps

Recommended Approach

Given the complexity of the remaining coordinator-api functionality, a phased migration approach is recommended:

1. Phase 16: Document coordinator-api router structure

   • Document all routers and their endpoints
   • Identify dependencies between routers
   • Prioritize high-usage endpoints

2. Phase 17: Create dedicated microservices for remaining functionality

   • Miner Service (for miner operations)
   • AI Service (for AI job operations)
   • Explorer Service (for blockchain explorer operations)
   • Plugin Service (for plugin operations)
   • OpenClaw Service (for OpenClaw operations)

3. Phase 18: Migrate CLI to use new microservices

   • Update CLI configuration
   • Update CLI commands
   • Test CLI with new microservices

4. Phase 19: Decommission coordinator-api

   • Verify all functionality migrated
   • Update documentation
   • Remove coordinator-api service

Systemd Services

All microservices are managed by systemd:

• aitbc-gpu.service - GPU Service
• aitbc-marketplace.service - Marketplace Service
• aitbc-trading.service - Trading Service
• aitbc-governance.service - Governance Service
• aitbc-api-gateway.service - API Gateway
• aitbc-coordinator-api.service - Legacy Coordinator API

Database Schema

Each microservice has its own PostgreSQL database:

• aitbc_gpu - GPU Service database
• aitbc_marketplace - Marketplace Service database
• aitbc_trading - Trading Service database
• aitbc_governance - Governance Service database
• aitbc - Coordinator API database (legacy)

Testing

• Unit tests created for all microservices (pytest)
• API Gateway routing tested for all services
• CLI commands tested with new microservices
• Health endpoints verified for all services

Issues Resolved

1. Async session dependency issue: Fixed in all microservices by creating get_session_dep() function
2. Model import errors: Fixed by using correct model names from domain files
3. CLI argument parsing: Updated CLI handlers to use microservice URLs
4. API Gateway routing: Verified all services routing correctly

Conclusion

The microservices migration is progressing well. The core GPU and marketplace functionality has been successfully migrated to dedicated microservices. The CLI has been updated to use the new microservices, and the API Gateway is routing requests correctly.

The remaining coordinator-api functionality is more complex and involves multiple domains. A phased approach is recommended to complete the migration without disrupting existing functionality.
