Production-Grade AKS Cluster with Terraform
π― Problem Statement Organizations moving to Kubernetes often struggle with: Manual cluster provisioning leading to configuration drift Lack of security hardening and compliance controls No standardized approach to cluster lifecycle management Difficulty reproducing environments consistently π‘ Solution Overview I designed and implemented a fully automated AKS deployment pipeline using Terraform that provisions production-grade Kubernetes clusters with built-in security, monitoring, and networking configurations. ποΈ Architecture β β β β β β β β β β β β β β β β β β β β β β β β β β β β β β β β β β β β β β β β β β β β β β β β β β β β β β β β β β β β β β β β β β β β β β β β β β β β β β β β β β β β β β β β β β β β β β β β β β β β β β β β β β β β β β β β β β β A I C β β A + β β β β β β β β β β β β β β β β β p n o β β z β β β β β β β A β β β β β β p g n β β u L β β β β β β β z β S ( β β S ( β β β r t β β r o β β β β β β β u β u A β β u A β β β G e r β β e g β β β β β β β r β b K β β b p β β β a s o β β β β β β β β β e β n S β β n p β β β t s l β β M A β β β β β β β β e ) β β e G β β β e l β β o n β β β β β β β V β t β β t W β β β w e β β n a β β β β β β β N β β β ) β β β a r β β i l β β β β β β β e β 1 β β 2 β β β y β β t y β β β β β β β t β β β β β β β β o t β β β β β β β β β β β β β β β r i β β β β β β β β β β β β β β β β β β β c β β β β β β β β β β β β s β β β β β β β β β β β β β β β β β β R β β β βΌ β β β β β β β β β β β β β β β β β β β A β β e β β β β β z β β s β β β β β u β β o β β β βΌ β β β β β β β β β β βΌ β β β β β β β β β β r β β u β β β β β β β β β e β β r β βΊ βΊ β β β β β β β β c β β β β β β β β β β β β β β β β β β β β β β S β β e β β β β β β β β β β β C ( β β β β u β β β β β β β β β β β β β o A β β β β b β β G β β β β β β β β β β β n C β β β β s β β r β β S ( β β U ( β β A β β A ( β β β t R β β β β c β β o β β y 3 β β s s β β z β β z s β β β a ) β β β β r β β u β A β s β β e p β β u β β u e β β β i β β β β i β β p β K β t n β β r o β β r β β r c β β β n β β β β p β β β S β e o β β t β β e β β e r β β β e β β β β t β β β β m d β β N β β β β e β β β r β β β β i β β β C β e β β o i β β C β β K t β β β β β β β o β β β l β N s β β d n β β N β β e s β β β R β β β β n β β β u β o , β β e s β β I β β y β β β e β β β β β β β s β d β β t β β β β m β β β g β β β β β β β t β e a β β P a β β + β β V g β β β i β β β β β β β e β u β β o n β β β β a m β β β s β β β β β β β r β P t β β o c β β C β β u t β β β t β β β β β β β β o o β β l e β β a β β l ) β β β r β β β β β β β β o s β β s β β l β β t β β β y β β β β β β β β l c β β ) β β i β β β β β β β β β β β β β a β β β β c β β β β β β β β β β β β β l β β β β o β β β β β β β β β β β β β e β β β β β β β β β β β β β β β β β ) β β β β β β β β β β β β β β β β β β β β β β β β β β β β β β β β β β β β β β β β β β β β β β β β β β β β β β β β β β β β β β β β β β β β β β β β β β β β β β β β β β β β β β β β β β β β β β β β β β β β β β β β β β β β β β β β β β β β β β β β β β β β β β β β β β β β β β β β β β β β β β β β β β β β β β β β β β€ β β β β β β β β β β β β β β β β β β β π οΈ Technologies Used Category Technology IaC Terraform 1.5+ Cloud Provider Microsoft Azure Container Orchestration Azure Kubernetes Service (AKS) Networking Azure CNI, Calico Network Policies Ingress Application Gateway Ingress Controller Secrets Management Azure Key Vault + CSI Driver Monitoring Azure Monitor, Prometheus, Grafana CI/CD GitHub Actions State Management Azure Storage Backend π Project Structure a β β β β β β β β β β β β β β β β β k β β β β β β s β β β β β β -
