VM Bundles Overview¶

VM Bundles are pre-configured, ready-to-deploy virtual machine images available in the DevOpsCentral marketplace. These bundles provide turnkey solutions for common applications and development environments, allowing you to deploy production-ready software stacks in minutes without complex configuration or setup.

Each bundle is optimized for DevOpsCentral infrastructure, comes with sensible defaults, and includes documentation for customization and ongoing maintenance. Whether you need a database server, web development environment, or complete application stack, VM Bundles eliminate the time and complexity of manual installation and configuration.

All bundles are built with security best practices, regularly updated for patches and improvements, and designed to integrate seamlessly with DevOpsCentral's sovereignty-focused infrastructure.

Deployment Process¶

Quick Deployment Steps¶

Browse Marketplace - Find your desired bundle in DevOpsCentral dashboard
Select Flavor - Choose appropriate VM size
Configure Network - Select or create network and security groups
Launch Bundle - Deploy with one click
Access & Configure - Connect via SSH and customize
Secure - Change default passwords and update settings

Post-Deployment¶

After launching a bundle:

📝 Review documentation - Each bundle has specific setup notes
🔐 Change credentials - Update default passwords immediately
🔧 Customize configuration - Adjust for your use case
🔒 Update firewall - Configure security groups appropriately
💾 Setup backups - Configure snapshot schedules
📊 Enable monitoring - Track performance and health

Best Practices¶

Security¶

✅ Change default passwords immediately after deployment
✅ Restrict network access using security groups
✅ Enable automatic security updates
✅ Use SSH key authentication (disable password auth)
✅ Review exposed ports and close unnecessary ones
✅ Enable SSL/TLS for web services
✅ Regular security audits and updates

Management¶

✅ Document customizations for team knowledge
✅ Snapshot before major changes
✅ Monitor resource usage and scale appropriately
✅ Test backup restoration procedures
✅ Keep services updated with latest patches
✅ Plan for disaster recovery

Performance¶

✅ Right-size your VM based on actual workload
✅ Use appropriate storage types (SSD vs NVMe)
✅ Enable caching where applicable
✅ Monitor performance metrics
✅ Optimize database queries and configurations

Default Credentials

All bundles come with documented default credentials. You must change these immediately after deployment for security. Never use default credentials in production!

Bundles on Sovereign Infrastructure

All VM Bundles run on DevOpsCentral's locally-owned infrastructure, ensuring your applications and data benefit from data sovereignty and regulatory compliance.

Customization

Bundles are starting points. Feel free to customize, add software, or modify configurations to match your specific requirements.
