May 1, 2026For May 2026, delivered security-focused cleanup and naming standardization in the kubernetes-on-aws module. Implemented removal of EKS control plane logging config from end-to-end tests, tightened IAM role permissions to reduce exposure, and standardized the EKS Control Plane delivery stream naming. These changes reduce sensitive data exposure, improve maintainability, and set a foundation for safer, more auditable deployments.

Aug 1, 20252025-08 monthly summary for zalando-incubator/kubernetes-on-aws: Implemented EKS control plane logging enablement and lifecycle improvements with a focus on reliability, observability, and maintainability. Delivered a dedicated CloudFormation log group with retention, added dependency management so cluster creation waits for the log group when logging is enabled, and introduced a migration/config flag to enable safe rollout. Reorganized CloudFormation templates (placing ControlPlaneLogGroup next to the EKSCluster resource), standardized log group naming, and disabled control plane logging in the end-to-end environment to reduce noise. Post-migration cleanup removed legacy log config items to minimize configuration drift and optimize maintenance.
