Overview

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.

<note markdown=“1”> This object isn’t applicable to jobs that are running on Fargate resources.

  SENSITIVE = []
  include Aws::Structure
end

#version ⇒ String

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, 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 *Batch User Guide*.

Default: ‘$Default`.
