Key Features

1. Three Deployment Modes

Interactive Mode

• Purpose: First-time users, exploratory deployments
• Implementation: Launches Rust TUI installer
• Usage: nu -c "use mod.nu *; deploy-interactive"

Headless Mode

• Purpose: Scripted deployments, known configurations
• Implementation: CLI arguments, no prompts
• Usage: nu -c "use mod.nu *; deploy-headless docker solo --auto-confirm"

Unattended Mode

• Purpose: CI/CD pipelines, automated deployments
• Implementation: Config file/MCP/API driven
• Usage: nu -c "use mod.nu *; deploy-unattended file ./config.toml"

2. Platform Support

Platform	Implementation	Status
Docker	docker-compose with overlays	✅ Complete
Podman	podman-compose	✅ Complete
Kubernetes	kubectl with manifests	✅ Complete
OrbStack	Native macOS integration	✅ Complete

3. Deployment Modes

Mode	Services	Resources	Use Case
Solo	3-7	2 CPU, 4GB RAM	Single developer
Multi-User	7-9	4 CPU, 8GB RAM	Team collaboration
CI/CD	8-10	8 CPU, 16GB RAM	Automation pipelines
Enterprise	15+	16 CPU, 32GB RAM	Production

4. External Integrations

• MCP Server: Load config via Model Context Protocol
• REST API: Fetch config from external APIs
• Webhooks: Send notifications (Slack, Discord, Teams)
• Rust Installer: Call installer binary with configs

5. Robust Error Handling

• Prerequisites validation
• Configuration validation (normal + strict mode)
• Health checks post-deployment
• Automatic rollback on failure
• Comprehensive error messages

Implementation Highlights

Follows Nushell Best Practices

All scripts adhere to .claude/best_nushell_code.md:

1. Single Purpose Functions: Each function does one thing
2. Explicit Type Signatures: All parameters and returns typed
3. Early Validation: Fail fast with clear errors
4. Pure Functions: Side effects marked with ! suffix
5. Atomic Operations: Complete success or complete failure
6. Pipeline Operations: Prefer pipelines over loops
7. Structured Errors: Consistent error records
8. Self-Documenting: Clear naming, inline docs

Code Quality

• No unwraps(): Proper error handling throughout
• Type Safety: Explicit types for all functions
• Modular Design: Clear separation of concerns
• Comprehensive Validation: Multi-layer validation
• Progress Tracking: Real-time status updates
• Idiomatic Nushell: Following community patterns

Configuration-Driven

• TOML configuration files
• Environment variable generation
• Secret management
• Platform-specific overlays
• Strict validation mode

nu -c "use mod.nu *;
let config = load-config-from-file ./configs/solo-example.toml;
validate-deployment-config $config --strict
"

# Platform availability
nu -c "use mod.nu *; check-platform-availability docker"

# Module info
nu -c "use mod.nu *; module info"

Integration Testing

nu -c "use mod.nu *; deploy-headless docker solo --config-only"

# Test Kubernetes deployment
nu -c "use mod.nu *; deploy-headless kubernetes solo --config-only"

# Test config loading
nu -c "use mod.nu *;
let config = load-config-from-file ./configs/solo-example.toml;
print $config
"

Integration with Rust Installer

The Nushell scripts complement the Rust TUI installer:

1. Interactive Mode: Calls Rust installer directly
2. Headless Mode: Can optionally use Rust installer with CLI args
3. Unattended Mode: Standalone or via Rust installer
4. Config Conversion: Converts config to installer CLI args
5. Status Tracking: Queries installer status

Integration Functions

# Call installer with config
nu -c "use mod.nu *;
let config = load-config-from-file ./config.toml;
deploy-with-installer $config --auto-confirm
"

# Get installer path
nu -c "use mod.nu *; get-installer-path"

# Convert config to CLI args
nu -c "use mod.nu *;
let config = load-config-from-file ./config.toml;
config-to-cli-args $config
"

Deployment Workflow

Standard Workflow

1. Prerequisites Check: Validate tools and resources
2. Load Configuration: From file/MCP/API
3. Validate Config: Normal or strict validation
4. Platform Check: Verify platform availability
5. Generate Secrets: Create secure credentials
6. Create Manifests: Platform-specific deployment files
7. Deploy Services: Execute platform deployment
8. Health Check: Verify all services healthy
9. Rollback if Failed: Automatic cleanup on errors

Unattended Workflow (CI/CD)

1. Load config from source (file/MCP/API)
2. Strict validation
3. Prerequisites check
4. Progress tracking with webhooks
5. Step-by-step deployment
6. Health checks
7. Success/failure notifications
8. Automatic rollback on failure

Error Handling

Validation Errors

• Missing required fields
• Invalid platform/mode values
• Required services not enabled
• Resource constraints not met

Deployment Errors

• Platform not available
• Service startup failures
• Health check failures
• Network connectivity issues

Rollback Scenarios

• Health checks failed
• Service deployment failed
• Configuration errors detected
• User cancellation

Best Practices

1. Use Configuration Files: Version-controlled TOML configs
2. Enable Strict Validation: For production deployments
3. Configure Webhooks: Monitor deployment progress
4. Test Before Production: Use --config-only flag
5. Automated Health Checks: Always verify deployment
6. Idempotent Operations: Safe to retry failed deployments
7. Comprehensive Logging: Track all operations
8. Secret Management: Never hardcode secrets

Future Enhancements

Potential improvements for future versions:

• Add support for Nomad orchestrator
• Implement blue-green deployments
• Add canary deployment support
• Terraform provider integration
• Ansible playbook generation
• Multi-cloud deployment support
• Advanced monitoring integrations
• Backup and restore functionality

Troubleshooting

Common Issues

1. Prerequisites Check Failed: Install missing tools
2. Platform Not Available: Start platform daemon
3. Health Checks Failed: Check service logs
4. Config Validation Failed: Review error messages
5. Deployment Timeout: Increase resource limits

Debug Commands

# Verbose output
nu --log-level debug -c "use mod.nu *; deploy-headless docker solo"

# Check service logs
docker-compose logs -f orchestrator
kubectl logs -n provisioning-platform deployment/orchestrator

# Manual health check
