Migration to Kubernetes (Phases 11-14)

Phase 11: Manifest Creation

Convert Compose → K8s:

Services → Deployments
Networks → Network Policies
Volumes → PersistentVolumeClaims
Environment → ConfigMaps/Secrets

Tools:

kompose (for initial conversion)
Manual refinement for production
Add K8s-specific features

Phase 12: Service Mesh & HA

Add:

Linkerd service mesh
HorizontalPodAutoscaler
PodDisruptionBudget
Multi-replica deployments
Database replication

Phase 13: Testing

Comprehensive testing:

Load testing on K8s
Failover testing
Security testing
Performance benchmarks

Phase 14: Production

Deploy to Ubuntu server:

Full K8s cluster
Production monitoring
Backup procedures
Documentation

Timeline

Compose Development (Phases 0-10)

Duration: ~70-85 hours % of Total Work: ~75%

Benefit: Get full working system before K8s complexity

Kubernetes Migration (Phases 11-14)

Duration: ~20-25 hours % of Total Work: ~25%

Benefit: Migrate proven, working system to K8s

Key Advantages of Compose-First

1. Lower Learning Curve

Start coding immediately
No K8s YAML complexity
Familiar Docker Compose syntax

2. Faster Iteration

Quick service restarts
Easier debugging
Simpler logs access

3. Same Architecture

Microservices from day one
Proper service boundaries
Production-like structure

4. Proven Before K8s

All features working
All bugs fixed
Performance optimized
Then migrate to K8s

5. Easy Migration

Same Docker images
Same environment variables
Same service discovery
Just different orchestration

What Each Phase Document Will Include

Section A: Docker Compose Implementation

Objectives - What this phase accomplishes
Prerequisites - What must exist before starting
Entry Checklist - Verify before beginning
Step-by-Step Tasks - Detailed implementation
Code Examples - docker-compose.yml snippets, Dockerfiles
Testing Procedures - How to verify it works
Troubleshooting - Common issues and solutions
Documentation Updates - What docs to update
Exit Checklist - Completion criteria

Section B: Kubernetes Migration Notes

K8s Equivalents - Compose → K8s mapping
Manifest Examples - K8s YAML examples
Migration Steps - How to migrate this phase
K8s-Specific Features - What to add in K8s
Production Considerations - HA, scaling, etc.

Decision Point

Option 1: Create All 14 Phase Documents Now

Pros:

Complete roadmap ready
Can start Phase 0 immediately
Clear path forward

Cons:

Takes 2-3 hours to create all docs
May need adjustments during development

Option 2: Create Phases 1-3, Then Rest As-Needed

Pros:

Start development sooner
Can adjust based on learning
Less upfront documentation

Cons:

Need to pause for doc creation later
May lose context between phases

Option 3: Start Phase 0 Now, Create Docs Incrementally

Pros:

Immediate development start
Maximum flexibility
Docs reflect reality

Cons:

Need me available for each phase doc
May slow down between phases

My Recommendation

Create all phase documents now (Option 1)

Reasoning:

Complete roadmap = clear path
Phase documents are templates for Claude Code
Can reference future phases during current work
Better planning = fewer surprises
Only ~2-3 hours to create all docs
Then focus entirely on development

What I Need From You

Please choose one:

A. "Create all 14 phase documents now" → I'll create comprehensive docs for Phases 1-14 → Each with Compose-first and K8s migration sections → Takes ~2 hours, then ready to start development

B. "Create Phases 1-5 now, rest later" → I'll create first 5 detailed phase docs → Create remaining 9 as needed → Can start development sooner

C. "Just create Phase 1, I'll request others as needed" → I'll create only Phase 1 detailed doc → You request each subsequent phase doc when ready → Maximum flexibility

D. "Start Phase 0 implementation now" → Skip doc creation, Claude Code begins Phase 0 → I'll create phase docs on-demand

Current Status

✅ Complete:

DEVELOPMENT_PHASES_V2.md (Compose-first overview)
ARCHITECTURE_V2.md (updated for Compose-first)
PHASE_00_INITIALIZATION.md (comprehensive Phase 0 doc)
CURRENT_PHASE.md (tracking system)

⏳ Remaining:

13 more phase documents (1-14)
SECURITY_COMPLIANCE.md
NEXTCLOUD_INTEGRATION.md
COMPOSE_TO_K8S_MIGRATION.md
Update ENHANCEMENT_SUMMARY.md

Estimated Time

Creating all remaining docs: 2-3 hours
Then starting Phase 0 development: 4-6 hours
Total to functional system: ~100-110 hours (all phases)

Ready to Proceed

Please tell me your choice (A, B, C, or D) and I'll proceed accordingly.

If you choose A (recommended), I'll create all phase documents in the next session and you'll have a complete development roadmap ready to execute.
