Services or capabilities described in AWS documentation might vary by Region. To see the differences applicable to the AWS European Sovereign Cloud Region, see the AWS European Sovereign Cloud User Guide.

Update the Kubernetes version of the compute environment

With AWS Batch, you can update the Kubernetes version of a compute environment to support Amazon EKS cluster upgrades. The Kubernetes version of a compute environment is the Amazon EKS AMI version for the Kubernetes nodes that AWS Batch launches to run jobs. You can perform a Kubernetes version upgrade on their Amazon EKS nodes before or after you update the version of Amazon EKS cluster's control-plane. We recommend that you update the nodes after upgrading the control plane. For more information, see Updating an Amazon EKS cluster Kubernetes version in the Amazon EKS User Guide.

To upgrade the Kubernetes version of a compute environment, use the UpdateComputeEnvironment API operation.

$ aws batch update-compute-environment \
    --compute-environment <compute-environment-name> \
    --compute-resources \
      'ec2Configuration=[{imageType=EKS_AL2,imageKubernetesVersion=1.32}]'
