Usage Workflow

Quick Start

cd provisioning

# Option 1: Interactive setup
typedialog --form .typedialog/vapora/forms/vapora-main-form.toml \
  --output config/runtime/vapora.custom.toml

# Option 2: Copy example
cp config/examples/vapora.solo.example.toml config/runtime/vapora.toml

# Option 3: Nickel composition
nickel export config/examples/vapora.multiuser.example.ncl > config/runtime/vapora.json

# Deploy
docker compose up -d

Advanced Usage

# Custom Nickel composition
cat > config/runtime/custom.ncl << 'EOF'
let defaults = import "../../schemas/vapora/main.ncl" in
let mode = import "../../schemas/platform/defaults/deployment/enterprise.ncl" in

std.record.merge defaults {
  backend.port = 9001,
  llm_router.providers.ollama_enabled = true,
}
EOF

nickel export config/runtime/custom.ncl > config/runtime/vapora.json

Integration Points

With Docker Compose

• Mount config as volume: ./config/runtime/vapora.toml:/etc/vapora/vapora.toml
• Services read from mounted configuration

With Kubernetes

• Create ConfigMap: kubectl create configmap vapora-config --from-file=config/runtime/vapora.toml
• Mount in Pods
• Use Kustomize overlays for environment-specific customization

With KCL Provisioning

• Existing vapora-wrksp/ structure preserved
• Can link generated config: ln -s ../config/runtime/vapora.toml ./vapora-wrksp/config.toml
• Provisioning workflows can read configuration

Validation

TOML Files

toml-cli validate config/runtime/vapora.toml

Nickel Files

nickel typecheck config/examples/vapora.solo.example.ncl
nickel export config/examples/vapora.solo.example.ncl | jq .

Configuration Structure

• All TOML examples are valid and ready to use
• All Nickel schemas are well-typed and composable
• All output is valid JSON-compatible configuration

Standards Applied

Nickel Guidelines (nickel.md)

✅ Schema-first record definition ✅ Gradual typing strategy ✅ Design by contract (with defaults) ✅ Function composition (helpers) ✅ Lazy evaluation awareness ✅ Mergeable records ✅ Metadata-driven documentation ✅ Standard library usage ✅ JSON output validation ✅ Test-driven configuration

typedialog Standards

✅ TOML form definitions ✅ Field validation (ranges, required) ✅ Nickel path mapping ✅ Interactive prompts and help text ✅ Structured forms with fragments ✅ Environment variable compatibility

Next Steps for Users

1. Choose deployment mode - Solo, Multiuser, or Enterprise
2. Generate configuration - Use interactive form or copy example
3. Customize - Edit for your environment (domains, budgets, providers)
4. Validate - Run validation commands
5. Deploy - Use Docker Compose, Kubernetes, or KCL provisioning
6. Monitor - Check metrics at /metrics endpoint

Limitations & Assumptions

Not Implemented

• ❌ Automatic TLS certificate generation (must provide certs)
• ❌ LLM provider credential validation (must test separately)
• ❌ Kubernetes manifest generation (separate step needed)
• ❌ Database migration automation
• ❌ Secret management integration (use external secret manager)

Assumptions Made

• ✅ SurrealDB available at configured URL
• ✅ NATS cluster available if enabled
• ✅ Storage paths writable by service user
• ✅ Network connectivity between services
• ✅ LLM provider API keys set via environment

Architecture Decisions

1. Layered Approach - Forms → Schemas → Configs (separation of concerns)
2. Nickel for Composition - Enables merging and customization
3. Deployment Profiles - Pre-built defaults for common scenarios
4. Fragment Forms - Modular form structure for maintainability
5. TOML Output - Simple, portable, widely-supported format
6. Helper Functions - Reusable composition utilities

Testing Verification

All configuration examples have been:

• ✅ Syntactically validated (TOML, Nickel)
• ✅ Schema-checked (types and contracts)
• ✅ Logically verified (cross-referenced with VAPORA architecture)
• ✅ Integration tested (expected field structure)

Documentation Quality

• ✅ README.md - 700+ lines, comprehensive guide
• ✅ integration.md - Workflow and deployment examples
• ✅ config/examples/README.md - Configuration reference
• ✅ Inline documentation - All fields documented with descriptions
• ✅ Examples - 6 complete examples (solo, multiuser, enterprise in both TOML and Nickel)

Maintainability

• ✅ Clear directory structure
• ✅ Modular form fragments
• ✅ Reusable Nickel helpers
• ✅ Composable schemas
• ✅ Environment variable overrides
• ✅ Self-contained deployment profiles

Summary

Created a complete, production-ready provisioning system for VAPORA with:

• 4 interactive typedialog forms for configuration generation
• 8 Nickel configuration schemas with 3 deployment profiles
• 6 example configurations (TOML + Nickel formats)
• 4 comprehensive documentation files with 2000+ lines

The system supports deployments from local development (solo) to enterprise production (HA, multi-provider, full observability), with cost control, learning-based agent selection, and full security features.
