Azure Kubernetes Service (AKS) Lesson

Introduction

Azure Kubernetes Service (AKS) is a managed container orchestration service provided by Microsoft Azure. It simplifies the deployment, management, and operations of Kubernetes. AKS allows you to run applications in containers while managing the underlying infrastructure.

Key Concepts

Understanding the following concepts is essential when working with AKS:

• **Clusters**: A set of nodes that run containerized applications.
• **Nodes**: Virtual machines that run your applications and workloads.
• **Pods**: The smallest deployable units in Kubernetes, which can contain one or more containers.
• **Services**: An abstraction that defines a logical set of Pods and a policy to access them.

Step-by-Step Setup

Follow these steps to set up AKS:

            graph TD;
                A[Start] --> B[Create Azure Account];
                B --> C[Open Azure Portal];
                C --> D[Create AKS Cluster];
                D --> E[Configure kubectl];
                E --> F[Deploy Applications];
                F --> G[Monitor and Manage];
            

Detailed Steps

1. Create an Azure account if you don't have one.
2. Log in to the Azure portal.
3. Navigate to "Kubernetes services" and click "Add".
4. Fill in the required fields such as Subscription, Resource Group, and Cluster Name.
5. Select the desired Kubernetes version and node size.
6. Review + create the cluster.
7. Once created, configure kubectl to connect to your AKS cluster using the command below:

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

8. Deploy your applications using YAML configuration files.

Best Practices

Here are some best practices to follow when using AKS:

• Use resource limits and requests to manage resource allocation.
• Implement proper network policies for security.
• Regularly update your Kubernetes version.
• Enable monitoring and logging to track performance.
• Use Azure Active Directory for authentication.
