KodeKloud Notes

In this lesson, you’ll build a strong foundation for deploying, managing, and scaling containerized applications on Azure Kubernetes Service (AKS). Whether you’re new to Kubernetes or looking to deepen your expertise, this module equips you with the essential concepts and hands-on skills to succeed in production environments.

By the end of this section, you will be able to:

Understand Kubernetes core components: pods, deployments, services, and namespaces
Provision and configure an AKS cluster via the Azure portal
Deploy applications using kubectl and implement scaling strategies
Manage container images with Azure Container Registry (ACR)
Perform application upgrades and rollbacks in AKS
Centrally govern multiple clusters using Azure Kubernetes Fleet

Prerequisites

Make sure you have:

An active Azure subscription
Azure CLI installed and logged in (az login)
Basic familiarity with Docker containers

Kubernetes Core Concepts

Resource Type	Purpose	Example CLI Command
Pod	Smallest deployable unit	`kubectl run nginx --image=nginx`
Deployment	Declarative updates and self-healing	`kubectl create deployment webapp --image=myregistry/webapp`
Service	Stable network endpoint for pods	`kubectl expose deployment webapp --port=80 --type=ClusterIP`
Namespace	Logical cluster partitioning	`kubectl create namespace dev-environment`

Lesson Overview

Kubernetes Fundamentals
Dive into pods, deployments, services, and namespaces—key building blocks for any AKS deployment.
Provisioning an AKS Cluster
Step through the Azure portal to create your cluster, configure networking, and set up node pools.
Application Deployment & Scaling
Use kubectl to deploy, scale, and update your applications seamlessly.
Container Image Management
Push and version images in Azure Container Registry (ACR), and integrate ACR with AKS for secure pulls.
Upgrades & Rollbacks
Implement rolling updates and rollbacks to maintain availability during application releases.
Centralized Fleet Management
Orchestrate multiple clusters with Azure Kubernetes Fleet for consistent policy enforcement and simplified operations.

The image shows an agenda with topics related to Kubernetes, including an overview, deploying an AKS cluster, scaling deployments, pushing images to ACR, upgrading applications, and Azure Kubernetes Fleet.

Let’s get started on this exciting journey into AKS!
