This repository contains resources and configuration scripts for building a custom EKS AMI with HashiCorp Packer. This is based on the same configuration that Amazon EKS uses to create the official Amazon EKS-optimized AMI.
The file CHANGELOG_AMS.md
in the project root contains the list of changes
made in this fork. The overarching aim of these changes is stability. Most
notably, this uses Ubuntu 18.04
instead of Amazon Linux 2. Because
Ubuntu uses ext4 rather than xfs, it avoids the disk corruption
issue affecting the official AMI. Likewise, setting up Docker log rotation
prevents worker nodes from failing due to full disks.
You must have Packer 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 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:
make
The Makefile runs Packer with the eks-worker-bionic.json
build specification
template and the amazon-ebs
builder. An instance is launched and the Packer Shell
Provisioner runs the
install-worker.sh
script on the instance to install software and perform other
necessary configuration tasks. Then, Packer creates an AMI from the instance
and terminates the instance after the AMI is created.
The EKS Terraform module simplifies deployment of infrastructure for an EKS cluster.
