Kubernetes Infrastructure & Platform Engineering

Project Overview

Built a comprehensive bare metal Kubernetes cluster provisioning platform, developing custom controllers and reconciliation logic to manage cluster lifecycle on bare metal infrastructure.

Key Achievements

• Kubernetes Components: Built custom Kubernetes controller, API server, and scheduler components for bare metal cluster management
• Reconciliation Logic: Developed state management system to ensure desired cluster configuration and handle cluster drift
• Bootstrap Service: Created service deployed on private bootstrap machines in client networks that pulled commands from centralized SaaS platform and reported status
• Bare Metal Provisioning: Implemented bare metal readiness detection using DHCP and TFTP protocols
• Agent-based Architecture: Developed agents installed on bare metal machines to handle cluster operations
• Infrastructure Automation: Leveraged Tinkerbell framework for automated bare metal provisioning workflows

Technologies Used

• Container Orchestration: Kubernetes (custom controllers, API server, scheduler)
• Programming: Go, Python
• Infrastructure: Terraform, bare metal provisioning
• Protocols: DHCP, TFTP for network boot and discovery
• Provisioning: Tinkerbell framework
• Architecture: SaaS platform with distributed agent-based management
