interface LaunchTemplateSpecificationProperty

Language	Type name
.NET	Amazon.CDK.AWS.Batch.CfnComputeEnvironment.LaunchTemplateSpecificationProperty
Java	software.amazon.awscdk.services.batch.CfnComputeEnvironment.LaunchTemplateSpecificationProperty
Python	aws_cdk.aws_batch.CfnComputeEnvironment.LaunchTemplateSpecificationProperty
TypeScript	@aws-cdk/aws-batch » CfnComputeEnvironment » LaunchTemplateSpecificationProperty

An object that represents a launch template that's 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.

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

Example

// The code below shows an example of how to instantiate this type.
// The values are placeholders you should change.
import * as batch from '@aws-cdk/aws-batch';
const launchTemplateSpecificationProperty: batch.CfnComputeEnvironment.LaunchTemplateSpecificationProperty = {
  launchTemplateId: 'launchTemplateId',
  launchTemplateName: 'launchTemplateName',
  version: 'version',
};

Properties

Name	Type	Description
launchTemplateId?	string	The ID of the launch template.
launchTemplateName?	string	The name of the launch template.
version?	string	The version number of the launch template, $Latest , or $Default .

---

launchTemplateId?

Type: string (optional)

The ID of the launch template.

---

launchTemplateName?

Type: string (optional)

The name of the launch template.

---

version?

Type: string (optional)

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.

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, AWS 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 AWS Batch User Guide .

Default: $Default .
