How to Deploy Azure Kubernetes Service with Azure CLI

Deploying an Azure Kubernetes Service (AKS) cluster is straightforward with the Azure CLI. Here’s a step-by-step guide to help you get started:

Prerequisites:

1. Azure Subscription: Ensure you have an active Azure subscription. You can sign up for a free account here.
2. Azure CLI: Install the Azure CLI. You can download and install it from here.

Step 1: Install Azure CLI

If you haven’t installed the Azure CLI yet, you can do so using the following commands:

On Windows:
Download and install from Azure CLI installation page.

On macOS:

brew update && brew install azure-cli

On Linux:

curl -sL https://aka.ms/InstallAzureCLIDeb | sudo bash

Step 2: Log in to Azure

Open a terminal and log in to your Azure account:

az login

This command will open a browser window where you can log in with your Azure credentials.

Step 3: Create a Resource Group

A resource group is a logical container into which Azure resources like web apps, databases, and storage accounts are deployed and managed.

az group create --name MyResourceGroup --location eastus

Step 4: Create an AKS Cluster

Create the AKS cluster using the following command:

az aks create --resource-group MyResourceGroup --name MyAKSCluster --node-count 1 --enable-addons monitoring --generate-ssh-keys

• --resource-group: The name of the resource group.
• --name: The name of the AKS cluster.
• --node-count: The number of nodes in the cluster.
• --enable-addons: Enable monitoring (Azure Monitor) for the cluster.
• --generate-ssh-keys: Generate SSH keys if you don’t have them already.

Step 5: Connect to the AKS Cluster

To manage and interact with your AKS cluster, you need to configure kubectl, the Kubernetes command-line tool.

1. Install kubectl:

   az aks install-cli

2. Get the cluster credentials:

   az aks get-credentials --resource-group MyResourceGroup --name MyAKSCluster

3. Verify connection:

   kubectl get nodes

Step 6: Deploy an Application to AKS

Now that your AKS cluster is set up and connected, you can deploy your first application.

1. Create a sample deployment:

   kubectl create deployment myapp --image=nginx

2. Expose the deployment as a service:

   kubectl expose deployment myapp --type=LoadBalancer --port=80

3. Get the external IP of the service:

   kubectl get service myapp

   After a few minutes, the EXTERNAL-IP field will show the public IP address of your application.

Additional Tips:

• Scaling: You can scale your deployment by adjusting the node count or using autoscaling features.
• Monitoring: Utilize Azure Monitor and Azure Log Analytics for monitoring and logging your AKS cluster.
• Security: Implement Azure Active Directory integration for secure access and role-based access control (RBAC).
