EKS cluster creation in AWS - Mini Project: Build & Apply

EKS Cluster Creation

📖 Scenario: You are working as a cloud engineer for a company that wants to deploy containerized applications using Kubernetes on AWS. Your task is to create an Amazon Elastic Kubernetes Service (EKS) cluster to manage and run these applications efficiently.

🎯 Goal: Build a basic EKS cluster configuration using AWS CloudFormation syntax. This cluster will serve as the foundation for deploying containerized applications on AWS.

📋 What You'll Learn

Create an EKS cluster resource with a specific name

Define the Kubernetes version for the cluster

Specify the role ARN for the EKS cluster

Add a VPC configuration with subnet IDs

Complete the cluster resource with all required properties

💡 Why This Matters

🌍 Real World

Creating an EKS cluster is a common task for deploying scalable containerized applications on AWS. This foundational setup enables teams to run Kubernetes workloads managed by AWS.

💼 Career

Cloud engineers and DevOps professionals frequently create and manage EKS clusters as part of infrastructure automation and container orchestration in AWS environments.

1

Create the EKS Cluster Resource

Create a CloudFormation resource called MyEKSCluster of type AWS::EKS::Cluster.

AWS

# Your code here
Resources:

Need a hint?

Start by defining the resource name and type exactly as shown.

2

Add Cluster Properties

Add a Properties section to MyEKSCluster with Name set to MyCluster and Version set to 1.24.

AWS

Resources:
  MyEKSCluster:
    Type: AWS::EKS::Cluster
    # Add Properties with Name and Version here

Need a hint?

Indent properties correctly under MyEKSCluster.

3

Add Role ARN and VPC Configuration

Inside Properties, add RoleArn set to arn:aws:iam::123456789012:role/EKSRole and a ResourcesVpcConfig section with SubnetIds set to a list containing subnet-abc123 and subnet-def456.

AWS

Resources:
  MyEKSCluster:
    Type: AWS::EKS::Cluster
    Properties:
      Name: MyCluster
      Version: '1.24'
      # Add RoleArn and ResourcesVpcConfig here

Need a hint?

Make sure RoleArn and ResourcesVpcConfig are inside Properties.

4

Complete the EKS Cluster Configuration

Ensure the full CloudFormation YAML includes the Resources section with MyEKSCluster resource fully configured with Type and Properties including Name, Version, RoleArn, and ResourcesVpcConfig with SubnetIds.

AWS

Resources:
  MyEKSCluster:
    Type: AWS::EKS::Cluster
    Properties:
      Name: MyCluster
      Version: '1.24'
      RoleArn: arn:aws:iam::123456789012:role/EKSRole
      ResourcesVpcConfig:
        SubnetIds:
          - subnet-abc123
          - subnet-def456
# Finalize the configuration here if needed

Need a hint?

Review the entire resource to confirm all required properties are present and correctly indented.
