kubectl configuration for EKS in AWS - Mini Project: Build & Apply

kubectl configuration for EKS

📖 Scenario: You have created an Amazon EKS (Elastic Kubernetes Service) cluster. Now you want to configure your local kubectl tool to connect and manage this cluster.This project will guide you step-by-step to set up the kubectl configuration correctly for your EKS cluster.

🎯 Goal: By the end, you will have a valid kubectl configuration file that allows you to interact with your EKS cluster from your local machine.

📋 What You'll Learn

Use the AWS CLI to get cluster details

Create a kubeconfig file with the correct cluster info

Set the current context to the EKS cluster

Verify the configuration is complete and valid

💡 Why This Matters

🌍 Real World

Setting up kubectl configuration is essential to manage Kubernetes clusters on AWS EKS from your local machine.

💼 Career

Cloud engineers and DevOps professionals frequently configure kubectl to deploy and manage applications on EKS clusters.

1

Retrieve EKS cluster name

Create a variable called cluster_name and set it to the exact string my-eks-cluster which is the name of your EKS cluster.

AWS

# Create a variable called cluster_name and set it to 'my-eks-cluster'
# Your code here

Need a hint?

The cluster name is a string. Use single quotes around it.

2

Set AWS region variable

Create a variable called region and set it to the exact string us-west-2 which is the AWS region where your EKS cluster is located.

AWS

cluster_name = 'my-eks-cluster'
# Create a variable called region and set it to 'us-west-2'
# Your code here

Need a hint?

The region is a string. Use single quotes around it.

3

Generate kubeconfig command string

Create a variable called kubeconfig_command and set it to the exact string that runs the AWS CLI command to update your kubeconfig for the EKS cluster. The command should be: aws eks update-kubeconfig --name my-eks-cluster --region us-west-2 using the variables cluster_name and region with an f-string.

AWS

cluster_name = 'my-eks-cluster'
region = 'us-west-2'
# Create a variable kubeconfig_command with the AWS CLI update-kubeconfig command using f-string
# Your code here

Need a hint?

Use an f-string to insert the variables into the command string.

4

Add command to run kubeconfig update

Add a line that uses the os module to run the kubeconfig_command string as a system command. First, import os at the top, then run os.system(kubeconfig_command).

AWS

cluster_name = 'my-eks-cluster'
region = 'us-west-2'
kubeconfig_command = f"aws eks update-kubeconfig --name {cluster_name} --region {region}"
# Import os and run os.system(kubeconfig_command)
# Your code here

Need a hint?

Use import os at the top and then os.system(kubeconfig_command) to run the command.
