Implementing Karpenter on Amazon EKS requires setting up an AWS EKS cluster, creating IAM roles for both the control plane and worker nodes, and deploying Karpenter using Terraform. The article provides a detailed, step-by-step guide for these processes, including the necessary configurations and commands to run.

Migrating Amazon EKS from version 1.29 to 1.32 involved careful planning and execution, focusing on upgrading Terraform modules, transitioning to Amazon Linux 2023, and implementing a blue/green deployment strategy to minimize downtime. The process highlighted the importance of addressing breaking changes, updating add-ons, and validating instance types to ensure a smooth upgrade across four clusters. Overall, the upgrade was completed in two weeks with minimal disruptions and enhanced security and performance.
