Amazon EKS adds managed CA rotation with automated lifecycle safeguards

Fri, 21 Aug 2026 11:18:28 +0000

Platform/SRE — Plan: EKS clusters created in 2018 have 10-year CAs now approaching expiry (~2028); audit cluster creation dates and schedule CA rotation this quarter — worker nodes must be replaced and external API clients updated to trust the successor CA before activation, which AWS will not do automatically.
CI/CD — Learn: Pipelines that connect directly to EKS API servers (kubectl, Helm deploys, kubeconfig-based auth) qualify as external clients under the shared-responsibility model and would need CA trust updates during any rotation; no immediate action required but worth noting when rotation is scheduled by Platform.
