[ aws . ec2 ]



Describes one or more versions of a specified launch template. You can describe all versions, individual versions, or a range of versions.

See also: AWS API Documentation

See 'aws help' for descriptions of global parameters.

describe-launch-template-versions is a paginated operation. Multiple API calls may be issued in order to retrieve the entire data set of results. You can disable pagination by providing the --no-paginate argument. When using --output text and the --query argument on a paginated response, the --query argument must extract data from the results of the following query expressions: LaunchTemplateVersions


[--dry-run | --no-dry-run]
[--launch-template-id <value>]
[--launch-template-name <value>]
[--versions <value>]
[--min-version <value>]
[--max-version <value>]
[--filters <value>]
[--cli-input-json <value>]
[--starting-token <value>]
[--page-size <value>]
[--max-items <value>]
[--generate-cli-skeleton <value>]


--dry-run | --no-dry-run (boolean)

Checks whether you have the required permissions for the action, without actually making the request, and provides an error response. If you have the required permissions, the error response is DryRunOperation . Otherwise, it is UnauthorizedOperation .

--launch-template-id (string)

The ID of the launch template. You must specify either the launch template ID or launch template name in the request.

--launch-template-name (string)

The name of the launch template. You must specify either the launch template ID or launch template name in the request.

--versions (list)

One or more versions of the launch template.


"string" "string" ...

--min-version (string)

The version number after which to describe launch template versions.

--max-version (string)

The version number up to which to describe launch template versions.

--filters (list)

One or more filters.

  • create-time - The time the launch template version was created.
  • ebs-optimized - A boolean that indicates whether the instance is optimized for Amazon EBS I/O.
  • iam-instance-profile - The ARN of the IAM instance profile.
  • image-id - The ID of the AMI.
  • instance-type - The instance type.
  • is-default-version - A boolean that indicates whether the launch template version is the default version.
  • kernel-id - The kernel ID.
  • ram-disk-id - The RAM disk ID.

Shorthand Syntax:

Name=string,Values=string,string ...

JSON Syntax:

    "Name": "string",
    "Values": ["string", ...]

--cli-input-json (string) Performs service operation based on the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton. If other arguments are provided on the command line, the CLI values will override the JSON-provided values. It is not possible to pass arbitrary binary values using a JSON-provided value as the string will be taken literally.

--starting-token (string)

A token to specify where to start paginating. This is the NextToken from a previously truncated response.

For usage examples, see Pagination in the AWS Command Line Interface User Guide .

--page-size (integer)

The size of each page to get in the AWS service call. This does not affect the number of items returned in the command's output. Setting a smaller page size results in more calls to the AWS service, retrieving fewer items in each call. This can help prevent the AWS service calls from timing out.

For usage examples, see Pagination in the AWS Command Line Interface User Guide .

--max-items (integer)

The total number of items to return in the command's output. If the total number of items available is more than the value specified, a NextToken is provided in the command's output. To resume pagination, provide the NextToken value in the starting-token argument of a subsequent command. Do not use the NextToken response element directly outside of the AWS CLI.

For usage examples, see Pagination in the AWS Command Line Interface User Guide .

--generate-cli-skeleton (string) Prints a JSON skeleton to standard output without sending an API request. If provided with no value or the value input, prints a sample input JSON that can be used as an argument for --cli-input-json. If provided with the value output, it validates the command inputs and returns a sample output JSON for that command.

See 'aws help' for descriptions of global parameters.
