GitOps & Kubernetes Automation

Implementing advanced GitOps workflows and high-performance container networking for scalable Kubernetes clusters.

Project Overview

This project focuses on architecting and managing Kubernetes clusters across GCP and on-premise environments (VMWare, Proxmox). The core objective was to enhance reliability, scalability, and security through automation and modern networking solutions.

Key Implementations

GitOps with ArgoCD

• Workflow Design: Designed and implemented GitOps workflows using ArgoCD to automate application deployment.
• Deployment Strategies: Implemented Blue-Green deployment strategies to ensure zero-downtime updates.
• Traffic Management: Successfully migrated traffic management from standard Ingress to the modern Gateway API for better service resilience and control.

Cilium CNI Integration

• eBPF Networking: Deployed Cilium as the Container Networking Interface (CNI) for new clusters.
• Performance & Security: Leveraged eBPF for high-performance networking, improved load balancing, and advanced network policies.
• Observability: Enhanced network visibility using Cilium’s Hubble (if applicable) and eBPF-based metrics.

Reliability & Security

• Resource Optimization: Integrated Kubernetes Resource Recommender (KRR) and Robusta.dev for intelligent resource utilization and automated issue detection.
• Secrets Management: Strengthened security by enforcing best practices in Kubernetes Secrets management.
• Container Security: Built secure, lightweight container images using multi-stage Docker builds.

Architecture Highlights

• Multi-Environment: Consistent deployment capability across Dev, Staging, and Production.
• Network Security: WireGuard implementation for secure internal system access and backup networking.
• Automation: Jenkins pipeline optimization for multi-service deployments with dynamic routing.

Technologies

• Orchestration: Kubernetes (GKE, On-Prem)
• GitOps: ArgoCD
• Networking: Cilium (eBPF), Gateway API
• Security: WireGuard, KRR, Robusta
