Amazon EKS optimized Amazon Linux AMI build script

Amazon Elastic Kubernetes Service (Amazon EKS) has open-source scripts that are used to build the Amazon EKS optimized AMI. These build scripts are available on GitHub.

The Amazon EKS optimized Amazon Linux AMI is built on top of Amazon Linux 2, specifically for use as a node in Amazon EKS clusters. You can use this repository to view the specifics of how the Amazon EKS team configures kubelet , Docker, the Amazon IAM Authenticator for Kubernetes, and more.

The build scripts repository includes a HashiCorp packer template and build scripts to generate an AMI. These scripts are the source of truth for Amazon EKS optimized AMI builds, so you can follow the GitHub repository to monitor changes to our AMIs. For example, perhaps you want your own AMI to use the same version of Docker that the Amazon EKS team uses for the official AMI.

The GitHub repository also contains the specialized bootstrap script that runs at boot time to configure your instance's certificate data, control plane endpoint, cluster name, and more.

Additionally, the GitHub repository contains our Amazon EKS node Amazon CloudFormation templates. These templates make it easier to spin up an instance running the Amazon EKS optimized AMI and register it with a cluster.

Amazon EKS optimized Amazon Linux 2 contains an optional bootstrap flag to enable the containerd runtime. When bootstrapped in Amazon EKS optimized accelerated Amazon Linux AMIs for version 1.21, AmazonInferentia workloads are not supported.
