A rollout is how Kubernetes updates your application (container image, config, etc.) in a Deployment without downtime. It replaces old pods with new ones gradually, based on the strategy you define. Rolling out a new application version in AKS (Azure Kubernetes Service) must be done carefully in production to minimize downtime, avoid errors, and ensure […]

A Deployment in AKS (or in Kubernetes in general) is a controller that manages the lifecycle of your application pods. It ensures that a defined number of replicas of your application are running at all times. ✅ Why We Use a Deployment in AKS: Purpose Description Scaling Easily scale your app up/down using kubectl scale

Think of Helm as a package manager for Kubernetes — like how: You can use Helm to install, configure, and manage applications on Kubernetes — without writing complex Kubernetes YAML files manually every time. Imagine installing a full app (like WordPress or PostgreSQL) on Kubernetes with just one command instead of writing dozens of config

In an AKS (Azure Kubernetes Service) manifest — which is just a standard Kubernetes manifest — a label is a key-value pair attached to Kubernetes objects (like pods, deployments, services, etc.) to organize and select them. 🔖 What is a Label? Labels are metadata that help you identify and group resources in Kubernetes. If we

When a Pod is deleted, Kubelet (the agent running on each AKS node) handles its graceful termination using a process called graceful shutdown. Here’s how it works: 1. User runs kubectl delete pod You (or a controller like Deployment) run: kubectl delete pod my-app This sends a delete request to the Kubernetes API server. 2.

In AKS, the restart policy defines how Kubernetes restarts containers inside a Pod when they exit (fail or stop). Restart Policy is Defined at the Pod Level It’s set in the Pod spec under .spec.restartPolicy. There are 3 types: Restart Policy Description Always Always restarts the container if it fails (default for regular Pods). OnFailure
