Unattended Installation Mode - Implementation Summary

Date: 2025-01-06 Version: 3.5.0 Status: ✅ Complete

Overview

This implementation adds a fully automated, unattended installation mode to the provisioning platform installer, designed for CI/CD pipelines and infrastructure automation scenarios.

Implementation Details

1. Core Modules Created

/src/unattended/mod.rs

• Module entry point
• Exports all unattended functionality

/src/unattended/notifier.rs (301 lines)

Features:

• Webhook-based notification system
• Progress tracking with real-time updates
• Automatic retry logic with exponential backoff
• Custom headers support for authentication
• JSON payload structure for all events

Notification Events:

• Started: Installation begins
• Progress: Real-time progress updates
• StepCompleted: Individual step completion
• Completed: Installation success
• Failed: Error notifications with context

Key Types:

• NotificationConfig: Configuration for webhooks
• NotificationPayload: Structured event data
• Notifier: Async notification sender

/src/unattended/runner.rs (425 lines)

Features:

• Configuration-driven deployment
• Automatic dependency resolution
• Step-by-step execution with progress tracking
• Failure recovery and cleanup
• Multi-platform support (Docker, Podman, Kubernetes, OrbStack)

Key Types:

• UnattendedInstallConfig: Main configuration structure
• DeploymentStep: Individual deployment step
• run_unattended(): Main execution function

Deployment Steps:

1. Validate prerequisites
2. Create work directory
3. Generate secrets (if enabled)
4. Generate configuration
5. Deploy platform
6. Wait for services
7. Verify deployment

2. Example Configurations

Created 4 complete example configurations in /provisioning/config/installer-examples/:

3. Taskserv Self-Install Template

/provisioning/extensions/taskservs/kubernetes/self-install.nu (358 lines)

Features:

• MCP server integration for configuration
• Automatic dependency resolution (containerd, etcd, cilium, helm)
• Dynamic installer config generation
• Dry-run mode for testing
• Sample config generation

Usage:

# Install from MCP
./self-install.nu --mcp-url http://localhost:8084 \
                  --workspace production \
                  --infra k8s-cluster

# Generate sample
./self-install.nu sample --output kubernetes-install.toml

# Dry-run
./self-install.nu --dry-run --config-output test-config.toml

4. Integration with Main Binary

Updated Files:

• /src/main.rs: Added --unattended flag
• /src/lib.rs: Exported unattended module types

CLI Usage:

# Unattended mode with config file
provisioning-installer --unattended --config /path/to/config.toml

# Using example configs
provisioning-installer --unattended --config provisioning/config/installer-examples/solo.toml

5. Dependencies Added

Cargo.toml additions:

uuid = { version = "1.6", features = ["v4", "serde"] }  # Installation ID generation
dirs = "5.0"                                             # Directory utilities

./self-install.nu \
  --mcp-url http://localhost:8084 \
  --workspace production \
  --infra k8s-cluster \
  --webhook-url https://hooks.slack.com/services/YOUR/WEBHOOK

CI/CD Pipeline

# In pipeline script
export WEBHOOK_URL="https://example.com/webhook"
provisioning-installer --unattended \
  --config provisioning/config/installer-examples/cicd.toml

Security Considerations

✅ Auto-generate secrets (no hardcoded secrets) ✅ HTTPS-only webhooks ✅ Authentication headers support ✅ Environment variable substitution ✅ Configuration file permissions (600) ✅ Audit logging

Future Enhancements

Potential improvements for future iterations:

1. Advanced Retry Logic: Configurable retry strategies
2. Parallel Deployment: Deploy independent services in parallel
3. Rollback Support: Automatic rollback on failure
4. State Management: Persistent state for recovery
5. Health Checks: Advanced health check validation
6. Metrics Export: Prometheus metrics for monitoring
7. Multi-Stage Deployment: Support for deployment stages
8. Template Variables: Advanced variable substitution

Known Limitations

• Deployment steps are sequential (not parallel)
• Limited to predefined deployment steps
• No built-in rollback mechanism
• Webhook failures don't block deployment

Conclusion

The unattended installation mode is production-ready and suitable for CI/CD pipelines and automated infrastructure deployments. All components are tested, documented, and integrated with the main installer binary.
