LaunchTemplateSpecification - Amazon Batch
Services or capabilities described in Amazon Web Services documentation might vary by Region. To see the differences applicable to the China Regions, see Getting Started with Amazon Web Services in China.

LaunchTemplateSpecification

An object representing a launch template associated with a compute resource. You must specify either the launch template ID or launch template name in the request, but not both.

If security groups are specified using both the securityGroupIds parameter of CreateComputeEnvironment and the launch template, the values in the securityGroupIds parameter of CreateComputeEnvironment will be used.

Note

This object isn't applicable to jobs that are running on Fargate resources.

Contents

launchTemplateId

The ID of the launch template.

Type: String

Required: No

launchTemplateName

The name of the launch template.

Type: String

Required: No

version

The version number of the launch template, $Latest, or $Default.

If the value is $Latest, the latest version of the launch template is used. If the value is $Default, the default version of the launch template is used.

Important

If the AMI ID that's used in a compute environment is from the launch template, the AMI isn't changed when the compute environment is updated. It's only changed if the updateToLatestImageVersion parameter for the compute environment is set to true. During an infrastructure update, if either $Latest or $Default is specified, Amazon Batch re-evaluates the launch template version, and it might use a different version of the launch template. This is the case even if the launch template isn't specified in the update. When updating a compute environment, changing the launch template requires an infrastructure update of the compute environment. For more information, see Updating compute environments in the Amazon Batch User Guide.

Default: $Default.

Type: String

Required: No
