Composition Architecture

Each configuration file follows the 4-layer composition pattern:

Layer 1: Schema Definition
  ↓ imports from ../../vapora/main.ncl
  Defines all fields, types, contracts

Layer 2: Constraints & Validation
  ↓ checked by Platform Constraints
  Validates values are in valid ranges

Layer 3: Defaults
  ↓ imports from ../defaults/common/ and ../defaults/deployment/
  Provides sensible starting values

Layer 4: User Customizations
  ↓ composable via helpers.compose_config()
  Allows final overrides for specific deployments

Configuration Files Breakdown

Solo Mode (vapora-solo.ncl)

Purpose: Development and testing

Composition:

let schema = import "../../vapora/main.ncl" in
let defaults_mode = import "../defaults/deployment/solo.ncl" in

helpers.compose_config schema defaults_mode {
  # User customizations (optional)
}

let defaults_mode = import "../defaults/deployment/enterprise.ncl" in

helpers.compose_config schema defaults_mode {
  # User customizations with detailed examples

Main Entry Point (main.ncl)

Purpose: Load all configurations in one place

Usage:

let configs = import "schemas/platform/configs/main.ncl" in

# Access each configuration
configs.solo
configs.multiuser
configs.enterprise

# Export all at once
configs.export.all

Export All:

nickel export schemas/platform/configs/main.ncl > all-vapora-configs.json

Customization Patterns

Pattern 1: Extend Solo for Testing

# test-vapora.ncl
let helpers = import "schemas/platform/common/helpers.ncl" in
let schema = import "schemas/vapora/main.ncl" in
let solo = import "schemas/platform/defaults/deployment/solo.ncl" in

helpers.compose_config schema solo {
  # Testing customizations
  monitoring.log_level = "debug",
  llm_router.providers.ollama_enabled = true,
  backend.port = 9001,
}

Pattern 2: Customize Multiuser for Specific Team

# team-vapora.ncl
let helpers = import "schemas/platform/common/helpers.ncl" in
let schema = import "schemas/vapora/main.ncl" in
let multiuser = import "schemas/platform/defaults/deployment/multiuser.ncl" in

helpers.compose_config schema multiuser {
  # Team-specific configuration
  frontend.api_url = "https://api.my-team.internal",

  llm_router.budget_enforcement.role_limits = {
    architect_cents = 750000,
    developer_cents = 500000,
    reviewer_cents = 300000,
    testing_cents = 150000,
  },

  agents.learning.recency_window_days = 14,
  monitoring.log_level = "info",
}

Pattern 3: Custom Enterprise with Regional Setup

# us-west-vapora.ncl
let helpers = import "schemas/platform/common/helpers.ncl" in
let schema = import "schemas/vapora/main.ncl" in
let enterprise = import "schemas/platform/defaults/deployment/enterprise.ncl" in

helpers.compose_config schema enterprise {
  # Regional customization
  frontend.api_url = "https://api.us-west.vapora.production",

  database.url = "ws://surrealdb-us-west.internal:8000",

  providers.ollama_url = "http://ollama-us-west.internal:11434",

  storage.base_path = "/mnt/production-us-west/vapora",
}

Export Workflows

Workflow 1: Generate JSON for Validation

# Export and validate JSON structure
nickel export schemas/platform/configs/vapora-multiuser.ncl | jq .

Workflow 2: Generate TOML Configuration

# Export to JSON, then render TOML template
nickel export schemas/platform/configs/vapora-solo.ncl | \
  jinja2 schemas/platform/templates/configs/toml.j2 > config.toml

# Use with backend
./vapora-backend --config config.toml

Workflow 3: Generate Docker Compose Stack

# Render docker-compose.yml from multiuser config
nickel export schemas/platform/configs/vapora-multiuser.ncl | \
  jinja2 schemas/platform/templates/docker-compose/docker-compose.yaml.j2 > docker-compose.yml

# Deploy
docker compose up -d

Workflow 4: Generate Kubernetes ConfigMap

# Render Kubernetes ConfigMap from enterprise config
nickel export schemas/platform/configs/vapora-enterprise.ncl | \
  jinja2 schemas/platform/templates/kubernetes/configmap.yaml.j2 > configmap.yaml

# Create ConfigMap in cluster
kubectl create -f configmap.yaml

# Or update existing
kubectl replace -f configmap.yaml

Workflow 5: Multi-File Deployment

# Generate all configurations
for mode in solo multiuser enterprise; do
  nickel export schemas/platform/configs/vapora-${mode}.ncl > vapora-${mode}.json
done

# Validate all
for f in vapora-*.json; do jq . "$f" > /dev/null && echo "✓ $f"; done

# Generate deployment artifacts
nickel export schemas/platform/configs/vapora-enterprise.ncl | \
  jinja2 schemas/platform/templates/kubernetes/configmap.yaml.j2 > configmap.yaml

nickel export schemas/platform/configs/vapora-enterprise.ncl | \
  jinja2 schemas/platform/templates/kubernetes/deployment.yaml.j2 > deployment.yaml

# Deploy to Kubernetes
kubectl apply -f configmap.yaml
kubectl apply -f deployment.yaml

Integration with Deployment Pipeline

CI/CD Integration

# In CI/CD pipeline (e.g., .github/workflows/deploy.yml)

# 1. Validate all configurations
for config in schemas/platform/configs/vapora-*.ncl; do
  nickel typecheck "$config" || exit 1
  nickel export "$config" | jq . > /dev/null || exit 1
done

# 2. Generate all outputs
nickel export schemas/platform/configs/vapora-${DEPLOYMENT_MODE}.ncl > config.json

# 3. Render templates
jinja2 schemas/platform/templates/kubernetes/configmap.yaml.j2 < config.json > configmap.yaml
jinja2 schemas/platform/templates/kubernetes/deployment.yaml.j2 < config.json > deployment.yaml

# 4. Deploy
kubectl apply -f configmap.yaml
kubectl apply -f deployment.yaml

Manual Deployment

# 1. Choose deployment mode
DEPLOYMENT_MODE=multiuser

# 2. Export configuration
nickel export schemas/platform/configs/vapora-${DEPLOYMENT_MODE}.ncl > vapora.json

# 3. Validate
jq . vapora.json > /dev/null && echo "✓ Configuration valid"

# 4. Generate Docker Compose (for local testing)
jinja2 schemas/platform/templates/docker-compose/docker-compose.yaml.j2 < vapora.json > docker-compose.yml

# 5. Deploy
docker compose up -d

# 6. Verify
docker compose ps

Key Benefits

✅ Composable - Mix and match schema, defaults, customizations ✅ Type-Safe - Schema defines all valid fields and types ✅ Validated - Constraints enforce valid value ranges ✅ Defaulted - Sensible defaults for each mode ✅ Customizable - Easy to override for specific needs ✅ Reproducible - Same config generates same output ✅ Version-Controlled - Configurations in Git ✅ Multi-Format - Generate JSON, TOML, YAML, K8s, Docker

Next Steps

1. Create Jinja2 templates for output formats:

   • templates/configs/{toml,yaml,json}.j2
   • templates/kubernetes/{deployment,configmap,service}.yaml.j2
   • templates/docker-compose/docker-compose.yaml.j2

2. Test composition with real exports:

   nickel export schemas/platform/configs/vapora-solo.ncl
   

3. Integrate with deployment pipeline:

   • Add validation steps
   • Generate outputs for each mode
   • Deploy via docker-compose or Kubernetes
