2-50 engineers, staging environment → Use `control-center-multiuser.ncl`\n- **Production**: Full enterprise deployment → Use `full-platform-enterprise.ncl`\n\n### Step 2: Export Configuration to TOML\n\n```\n# Start with solo mode\nnickel export --format toml orchestrator-solo.ncl > orchestrator.toml\n\n# Validate the export\ncat orchestrator.toml | head -20\n```\n\n### Step 3: Validate Configuration\n\n```\n# Typecheck the Nickel configuration\nnickel typecheck orchestrator-solo.ncl\n\n# Validate using provided script\nnu ../../scripts/validate-config.nu orchestrator-solo.ncl\n```\n\n### Step 4: Customize for Your Environment\n\nEdit the exported `.toml` or the `.ncl` file:\n\n```\n# Option A: Edit TOML directly (simpler)\nvi orchestrator.toml  # Change workspace path, port, etc.\n\n# Option B: Edit Nickel and re-export (type-safe)\nvi orchestrator-solo.ncl\nnickel export --format toml orchestrator-solo.ncl > orchestrator.toml\n```\n\n### Step 5: Deploy\n\n```\n# Docker Compose\nORCHESTRATOR_CONFIG=orchestrator.toml docker-compose up -d\n\n# Direct Rust execution\nORCHESTRATOR_CONFIG=orchestrator.toml cargo run --bin orchestrator\n\n# Kubernetes\nnu ../../scripts/render-kubernetes.nu solo\nkubectl apply -f provisioning/platform/infrastructure/kubernetes/*.yaml\n```\n\n---\n\n## Common Customizations\n\n### Changing Domain/Namespace\n\nIn any `.ncl` file at the top:\n\n```\nlet domain = "your-domain.com"\nlet namespace = "your-namespace"\nlet environment = "your-env"\n```\n\n### Increasing Resource Limits\n\nFor higher throughput:\n\n```\nqueue.max_concurrent_tasks = 200  # Default: 100\nsecurity.rate_limit.requests_per_second = 50000  # Default: 10000\nserver.workers = 32  # Default: 16\n```\n\n### Enabling Compliance Features\n\nFor regulated environments:\n\n```\npolicies.compliance.soc2.enabled = true\npolicies.compliance.hipaa.enabled = true\npolicies.audit.retention_days = 2555  # 7 years\n```\n\n### Custom Logging\n\nFor troubleshooting:\n\n```\nlogging.level = "debug"  # Default: info\nlogging.format = "text"  # Default: json (use text for development)\nlogging.outputs[0].level = "debug"  # stdout level\n```\n\n---\n\n## Validation & Testing\n\n### Syntax Validation\n\n```\n# Typecheck all examples\nfor f in *.ncl; do\n  echo "Checking $f..."\n  nickel typecheck "$f"\ndone\n```\n\n### Configuration Export\n\n```\n# Export to TOML\nnickel export --format toml orchestrator-solo.ncl | head -30\n\n# Export to JSON\nnickel export --format json full-platform-enterprise.ncl | jq '.orchestrator.server'\n```\n\n### Load in Rust Application\n\n```\n# With dry-run flag (if supported)\nORCHESTRATOR_CONFIG=orchestrator.solo.toml cargo run --bin orchestrator -- --validate\n\n# Or simply attempt startup\nORCHESTRATOR_CONFIG=orchestrator.solo.toml timeout 5 cargo run --bin orchestrator\n```\n\n---\n\n## Troubleshooting\n\n### "Type mismatch" Error\n\n**Cause**: Field value doesn't match expected type\n\n**Fix**: Check the schema for correct type. Common issues:\n- Use `true`/`false` not `"true"`/`"false"` for booleans\n- Use `9090` not `"9090"` for numbers\n- Use record syntax `{ key = value }` not `{ "key": value }`\n\n### Port Already in Use\n\n**Fix**: Change the port in your configuration:\n\n```\nserver.port = 9999  # Instead of 9090\n```\n\n### Database Connection Errors\n\n**Fix**: For multiuser/enterprise modes:\n- Ensure PostgreSQL is running: `docker-compose up -d postgres`\n- Verify credentials in environment variables\n- Check network connectivity\n- Validate connection string format\n\n### Import Not Found\n\n**Fix**: Ensure all relative paths in imports are correct:\n\n```\n# Correct (relative to examples/)\nlet defaults = import "../defaults/orchestrator-defaults.ncl" in\n\n# Wrong (absolute path)\nlet defaults = import "/full/path/to/defaults.ncl" in\n```\n\n---\n\n## Best Practices\n\n1. **Start Small**: Begin with solo mode, graduate to multiuser, then enterprise\n2. **Environment Variables**: Never hardcode secrets, use environment variables\n3. **Version Control**: Keep examples in Git with clear comments\n4. **Validation**: Always typecheck and export before deploying\n5. **Documentation**: Add comments explaining non-obvious configuration choices\n6. **Testing**: Deploy to staging first, validate all services before production\n7. **Monitoring**: Enable metrics and logging from day one for easier troubleshooting\n8. **Backups**: Regular backups of database state and configurations\n\n---\n\n## Adding New Examples\n\n### Create a Custom Example\n\n```\n# Copy an existing example as template\ncp orchestrator-solo.ncl orchestrator-custom.ncl\n\n# Edit for your use case\nvi orchestrator-custom.ncl\n\n# Validate\nnickel typecheck orchestrator-custom.ncl\n\n# Export and test\nnickel export --format toml orchestrator-custom.ncl > orchestrator.custom.toml\n```\n\n### Naming Convention\n\n- **Service + Mode**: `{service}-{mode}.ncl` (orchestrator-solo.ncl)\n- **Scenario**: `{service}-{scenario}.ncl` (orchestrator-high-throughput.ncl)\n- **Full Stack**: `full-platform-{mode}.ncl` (full-platform-enterprise.ncl)\n\n---\n\n## See Also\n\n- **Parent README**: `../README.md` - Complete configuration system overview\n- **Schemas**: `../schemas/` - Type definitions and validation rules\n- **Defaults**: `../defaults/` - Base configurations for composition\n- **Scripts**: `../scripts/` - Automation for configuration workflow\n- **Forms**: `../forms/` - Interactive TypeDialog form definitions\n\n---\n\n**Version**: 2.0\n**Last Updated**: 2025-01-05\n**Status**: Production Ready - All examples tested and validated\n\n## Using Examples\n\n### View Example\n\n```\ncat provisioning/.typedialog/provisioning/platform/examples/orchestrator-solo.ncl\n```\n\n### Copy and Customize\n\n```\n# Start with solo example\ncp examples/orchestrator-solo.ncl values/orchestrator.solo.ncl\n\n# Edit for your environment\nvi values/orchestrator.solo.ncl\n\n# Validate\nnu scripts/validate-config.nu values/orchestrator.solo.ncl\n```\n\n### Generate from Example\n\n```\n# Use example as base, regenerate with TypeDialog\nnu scripts/configure.nu orchestrator solo --backend web\n```\n\n## Example Structure\n\nEach example is a complete Nickel configuration:\n\n```\n# orchestrator-solo.ncl\n{\n  orchestrator = {\n    workspace = { },\n    server = { },\n    storage = { },\n    queue = { },\n    monitoring = { },\n  },\n}\n```\n\n## Configuration Elements\n\n### Workspace Configuration\n- **name** - Workspace identifier\n- **path** - Directory path\n- **enabled** - Enable/disable flag\n- **multi_workspace** - Support multiple workspaces\n\n### Server Configuration\n- **host** - Bind address (127.0.0.1 for solo, 0.0.0.0 for public)\n- **port** - Listen port\n- **workers** - Thread count (mode-dependent)\n- **keep_alive** - Connection keep-alive timeout\n- **max_connections** - Connection limit\n\n### Storage Configuration\n- **backend** - 'filesystem | 'rocksdb | 'surrealdb | 'postgres\n- **path** - Local storage path (filesystem/rocksdb)\n- **connection_string** - DB URL (surrealdb/postgres)\n\n### Queue Configuration (Orchestrator)\n- **max_concurrent_tasks** - Concurrent task limit\n- **retry_attempts** - Retry count\n- **retry_delay** - Delay between retries (ms)\n- **task_timeout** - Task execution timeout (ms)\n\n### Monitoring Configuration (Optional)\n- **enabled** - Enable metrics collection\n- **metrics_interval** - Collection frequency (seconds)\n- **health_check_interval** - Health check frequency\n\n## Creating New Examples\n\n### 1.

Save as Reference\n\n```\nmv examples/orchestrator-custom.ncl examples/orchestrator-{scenario}.ncl\n```\n\n## Best Practices for Examples\n\n1. **Clear documentation** - Explain the use case at the top\n2. **Realistic values** - Use production-appropriate configurations\n3. **Complete configuration** - Include all required sections\n4. **Inline comments** - Explain non-obvious choices\n5. **Validated** - Typecheck all examples before committing\n6. **Organized** - Group by service and deployment mode\n\n## Example Naming Convention\n\n- **Service-mode**: `{service}-{mode}.ncl` (orchestrator-solo.ncl)\n- **Scenario**: `{service}-{scenario}.ncl` (orchestrator-gpu-intensive.ncl)\n- **Full stack**: `full-platform-{mode}.ncl` (full-platform-enterprise.ncl)\n\n## Customizing Examples\n\n### For Your Environment\n\n```\n# orchestrator-solo.ncl (customized)\n{\n  orchestrator = {\n    workspace = {\n      name = "my-workspace",     # Your workspace name\n      path = "/home/user/projects/workspace",  # Your path\n    },\n    server = {\n      host = "127.0.0.1",        # Keep local for solo\n      port = 9090,\n    },\n    storage = {\n      backend = 'filesystem,     # No external DB needed\n      path = "/home/user/provisioning/data",  # Your path\n    },\n  },\n}\n```\n\n### For Different Resources\n\n```\n# orchestrator-multiuser.ncl (customized for team)\n{\n  orchestrator = {\n    server = {\n      host = "0.0.0.0",          # Public binding\n      port = 9090,\n      workers = 4,               # Team concurrency\n    },\n    queue = {\n      max_concurrent_tasks = 10,  # Team workload\n    },\n  },\n}\n```\n\n## Testing Examples\n\n```\n# Typecheck example\nnickel typecheck examples/orchestrator-solo.ncl\n\n# Evaluate and view\nnickel eval examples/orchestrator-solo.ncl | head -20\n\n# Export to TOML\nnickel export --format toml examples/orchestrator-solo.ncl > test.toml\n```\n\n---\n\n**Version**: 1.0.0\n**Last Updated**: 2025-01-05
