Azure AKS Cluster CLI Deployment

This repository provides a step-by-step guide to deploy an Azure Kubernetes Service (AKS) cluster using Azure CLI, along with a microservices application.

Prerequisites

  • Azure CLI
  • kubectl
  • Azure account with necessary permissions

Setup

  1. Install Azure CLI:
curl -sL https://aka.ms/InstallAzureCLIDeb | sudo bash
  1. Verify installation:
azure version
  1. Login to Azure:
vagrant@cloud-native-box:~/azure-aks-cluster-cli-deployment$ az version
{
  "azure-cli": "2.62.0",
  "azure-cli-core": "2.62.0",
  "azure-cli-telemetry": "1.1.0",
  "extensions": {}
}
vagrant@cloud-native-box:~/azure-aks-cluster-cli-deployment$

Install specific version

apt-cache policy azure-cli

Login via cli
