Support for Kubernetes version 1.33 in Amazon EKS will end on July 29, 2026. Starting this date, Amazon EKS clusters running on 1.33 with Kubernetes version policy set to extended will enter extended support. Kubernetes version 1.33 will remain in extended support until July 29, 2027. After July 29, 2027, Kubernetes 1.33 will no longer be supported on Amazon EKS, and all Amazon EKS clusters running on 1.33 will be automatically updated to Kubernetes version 1.34.

You are receiving this message because you currently have 1 or more Amazon EKS clusters running on Kubernetes version 1.33. If you have deleted, or already upgraded your EKS cluster, please disregard this message.

A list of your affected resource(s) can be found in the 'Affected resources' tab of your AWS Health Dashboard.

Amazon EKS clusters in extended support receive ongoing security patches for the Kubernetes control plane. Additionally, Amazon EKS releases critical patches for Amazon VPC CNI, kube-proxy, and CoreDNS add-ons, AWS-published EKS Optimized Amazon Machine Images (AMIs) for Amazon Linux and Bottlerocket, and EKS Fargate nodes for Kubernetes versions in extended support. All clusters in extended support are backed by technical support from AWS.

If you do not want to use extended support, we recommend that you update your 1.33 clusters to Kubernetes version 1.34 or newer before July 29, 2026. You can also opt-out of extended support by managing your Kubernetes version policy [1]. Amazon EKS clusters that are opted-out of extended support will have their control planes automatically upgraded at the end of standard support.

To learn more about the extended support versions pricing, see our announcement [2]. For instructions on how to update your cluster(s), see the Amazon EKS service documentation [3]. To learn more on Kubernetes version support, see the Amazon EKS service documentation [4]
