Kubernetes on Azure (AKS) Deep Dive

Kubernetes is a powerful container orchestration platform that automates the deployment, scaling, and management of containerized applications. Azure Kubernetes Service (AKS) is a managed Kubernetes service that simplifies the deployment and management of Kubernetes clusters on Azure.

AKS provides a simplified way to manage Kubernetes by handling the underlying infrastructure, allowing you to focus on managing your applications. Key features of AKS include:

• Automated Kubernetes version upgrades
• Integrated developer tools and CI/CD workflows
• Monitoring and diagnostics features
• Scaling and load balancing capabilities

To set up an AKS cluster, follow these steps:

1. Install Azure CLI: Ensure you have the Azure CLI installed and logged into your Azure account.
2. Create a resource group: Use the command:

az group create --name myResourceGroup --location eastus

3. Create the AKS cluster: Execute the following command:

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

4. Connect to the AKS cluster: Use the command:

az aks get-credentials --resource-group myResourceGroup --name myAKSCluster

Once your AKS cluster is set up, you can manage it using kubectl. Here are common management tasks:

• View cluster information: kubectl cluster-info
• List nodes: kubectl get nodes
• Deploy applications: kubectl apply -f deployment.yaml

AKS allows you to scale your applications easily. You can scale your cluster nodes or the number of pods. To scale the number of nodes, use:

az aks scale --resource-group myResourceGroup --name myAKSCluster --node-count 3

To scale the number of pods, modify the deployment YAML and apply the changes:

kubectl scale deployment myapp --replicas=5

To get the most out of AKS, consider the following best practices:

• Use managed identities for secure access management.
• Implement proper monitoring using Azure Monitor and Log Analytics.
• Regularly update your AKS cluster to the latest Kubernetes version.
• Utilize Azure Policy to enforce compliance and governance.
