Amazon EKS Amazon Linux 2 AMI deprecation
AWS ended support for Amazon EKS optimized Amazon Linux 2 AMIs on November 26, 2025. On October 27, 2025, AWS Batch changed the default AMI for new Amazon EKS compute environments to Amazon Linux 2023. Amazon EKS optimized Amazon Linux 2 AMIs no longer receive software updates, security patches, or bug fixes from AWS.
Important
If you have AWS Batch Amazon EKS compute environments still using Amazon Linux 2, we strongly recommend migrating to Amazon Linux 2023. It is your responsibility to maintain Amazon EKS optimized Amazon Linux 2 compute environments 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.
