This repository contains resources and configuration scripts for building a custom Amazon EKS AMI with HashiCorp Packer. This is the same configuration that Amazon EKS uses to create the official Amazon EKS-optimized AMI.
If you are new to Amazon EKS, we recommend that you follow our Getting Started chapter in the Amazon EKS User Guide. If you already have a cluster, and you want to launch a node group with your new AMI, see Launching Amazon EKS Worker Nodes.
You must have Packer version 1.8.0 or later installed on your local system. For more information, see Installing Packer in the Packer documentation. You must also have AWS account credentials configured so that Packer can make calls to AWS API operations on your behalf. For more information, see Authentication in the Packer documentation.
A Makefile is provided to build the Amazon EKS Worker AMI, but it is just a small wrapper around invoking Packer directly. You can initiate the build process by running the following command in the root of this repository:
# build an AMI with the latest Kubernetes version make # build an AMI with a specific Kubernetes version make 1.25
The Makefile chooses a particular kubelet binary to use per Kubernetes version which you can view here.
The default instance type to build this AMI does not qualify for the AWS free tier. You are charged for any instances created when building this AMI.
