Mixed AMI environments

You can use launch template overrides to create compute environments with both Amazon Linux 2 (AL2) and Amazon Linux 2023 (AL2023) AMIs. This is useful for using different AMIs for different architectures

Example configuration using both AMI types:

{
  "computeResources": {
    "launchTemplate": {
      "launchTemplateId": "TemplateId",
      "version": "1",
      "userdataType": "EKS_BOOTSTRAP_SH",
      "overrides": [
        {
          "instanceType": "c5.large",
          "imageId": "ami-al2-custom",
          "userdataType": "EKS_BOOTSTRAP_SH"
        },
        {
          "instanceType": "c6a.large",
          "imageId": "ami-al2023-custom",
          "userdataType": "EKS_NODEADM"
        }
      ]
    },
    "instanceTypes": ["c5.large", "c6a.large"]
  }
}
