AKS Deployment with Azure DevOps CI/CD
Containerized Web App — End to End
RG: rg-aks-devopsRegion: East USAKS Cluster: aks-platformACR: acrplatformpro3.azurecr.ioNamespace: devNode OS: Linux amd64
Overview
Built a complete containerized application lifecycle on Azure — from Docker build to ACR image storage, AKS deployment, and full production observability with Prometheus and Grafana. The Azure DevOps pipeline automates build, push, and deploy on every commit. Kubernetes Ingress handles external routing. AlertManager is configured for CPU, memory, pod crash, and replica mismatch alerts.
