# Service Configuration Template
# Use this as a pattern for migrating user configs to schema-validated versions
# This example shows the pattern for any service configuration

# Template for: SERVICE_NAME Configuration
# 1. Import the service schema
# 2. Import service defaults
# 3. Import deployment mode defaults
# 4. Import helpers for deep merge
# 5. Define user overrides (only fields to change)
# 6. Use compose_config to merge: defaults + mode + overrides
# 7. Validate with type annotation

let service_defaults = import "../defaults/SERVICE_NAME-defaults.ncl" in
let mode_config = import "../defaults/deployment/DEPLOYMENT_MODE-defaults.ncl" in
let helpers = import "../common/helpers.ncl" in

# Define user-specific overrides (only override what you need)
let user_overrides = {
  # Example: workspace configuration
  workspace = {
    name = "my-service",
    path = "/var/lib/provisioning/my-service",

  # Example: server configuration
  server = {
    host = "0.0.0.0",
    port = 9000,
    workers = 4,
  },

  # Example: storage configuration (use only schema-supported fields)
  storage = {
    backend = "filesystem",
    path = "/data/my-service",
  },

  # Add only the fields your service needs
  # Other fields will be provided by defaults
} in

# Compose: apply defaults, then mode-specific tuning, then user overrides
# This ensures all required fields have values
