Amazon EKS Amazon Linux 2 AMI deprecation

AWS will end support for Amazon EKS optimized Amazon Linux 2 AMIs, effective 11/26/25. We recommend migrating AWS Batch Amazon EKS compute environments to Amazon Linux 2023 prior to 11/26/25 to maintain optimal performance and security.

While you can continue using Batch-provided Amazon EKS optimized Amazon Linux 2 AMIs on your Amazon EKS compute environments beyond the 11/26/25 end-of-support date, these compute environments will no longer receive any new software updates, security patches, or bug fixes from AWS. It is your responsibility to maintain these compute environments on the Amazon EKS optimized Amazon Linux 2 AMI after end-of-life.

For more information about the Amazon EKS AL2 end-of-life, see Amazon EKS AMI deprecation FAQs in the Amazon EKS User Guide.
