Creating a managed node group using a launch template in Amazon Elastic Kubernetes Service (EKS) allows you to have more control over the configuration of your worker nodes. Launch templates offer advanced configuration options that aren’t available in the standard EKS managed node groups, such as specifying custom Amazon Machine Images (AMIs), additional EBS volumes, or specific instance metadata options. In this article, I’ll guide you through the process of creating a managed node group with a launch template in EKS.
Step 1: Prerequisites
Before you begin, ensure that you have the following:
An existing EKS cluster: You need a running EKS cluster. If you don’t have one, you can create it using the AWS Management Console, AWS CLI, or using tools like eksctl.
AWS CLI configured: Make sure the AWS CLI is installed and configured on your local machine with the appropriate permissions to create and manage EKS resources.
IAM Roles: Ensure that your EKS cluster has the necessary IAM roles and permissions to manage resources on your behalf.
Step 2: Retrieving details before creating the launch template.
Retrieving EKS optimized AMI: If you wish to use an EKS optimized AMI, then refer to this .
