The article provides a step-by-step guide for testing configuration scanners on a deliberately insecure Kubernetes deployment using Terraform and Helm. It outlines the setup of an EKS cluster with insecure application pods, detailing the commands needed for deployment, testing, and cleanup, while highlighting the various security vulnerabilities present in the deployed applications.

Deploying and autoscaling HCP Terraform agents on Amazon EKS Auto Mode enhances infrastructure management by optimizing resource utilization and automating capacity management. The integration of the HCP Terraform Operator with EKS Auto Mode enables intelligent scaling based on workload demands, eliminating manual intervention and reducing operational costs. This approach ensures sufficient agent capacity during peak periods and conserves resources during quieter times.

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.
