Production Readiness Assessment

​

Core Deployment (Phase 1): 85% Ready

• ✅ Download and install capsules
• ✅ Launch processes
• ✅ Configuration management
• ⚠️ Missing: ProcessSupervisor, systemd service, integration tests

​

Docker Integration (Phase 2): 30% Ready

• ⚠️ Stub implementations only
• ❌ Missing: Real Docker API, ECR auth, ZeroMQ bridge

​

Rollouts & Health (Phase 3): 90% Ready

• ✅ RolloutController complete
• ✅ HealthMonitor complete
• ❌ Missing: Integration tests

​

Overall: ~60% Production Ready

• Core deployment features work
• Docker features are stubs
• No integration/E2E testing
• Missing production infrastructure (systemd, monitoring)

​

Next Priority Actions

​

High Priority (Critical for Production)

2. Create systemd service file - 1 hour
3. Package HelloWorld as capsule - 2-3 hours
4. End-to-end integration test - 2-3 hours
5. Implement real Docker API client - 4-6 hours
6. Implement AWS ECR authentication - 2-3 hours

​

Medium Priority (Enhances Reliability)

1. Implement ProcessSupervisor - 3-4 hours
2. Implement ZeroMQ Docker bridge - 4-5 hours
3. Container health monitoring - 2-3 hours

​

Low Priority (Nice-to-Have)

1. ReverseTunnelAgent - 5-6 hours
2. CLI tool - 6-8 hours
3. Offline deployment bundles - 4-5 hours

​

Technical Debt & Decisions

​

Decisions Made

1. HttpClient Reuse: Successfully refactored to use existing roboticks::messaging::HttpClient instead of raw libcurl
2. ProcessSupervisor Deferred: Using direct process management in CapsuleManager for now
3. Docker CLI Stubs: Using system() calls to Docker CLI instead of API (temporary)
4. JSON Parsing: Ready for nlohmann/json but using stubs for now

​

Technical Debt

1. Docker API: Need to replace CLI stubs with proper REST API calls
2. AWS SDK: Need to integrate AWS SDK for ECR authentication
3. JSON Parsing: Implement proper JSON serialization/deserialization
4. Error Handling: Add comprehensive error recovery and retry logic
5. Logging: Integrate with roboticks-logging for structured logs
6. Metrics: Add telemetry for deployment operations
