modify-launch-template

Description

Modifies a launch template. You can specify which version of the launch template to set as the default version. When launching an instance, the default version applies when a launch template version is not specified.

See also: AWS API Documentation

See ‘aws help’ for descriptions of global parameters.

Synopsis

  modify-launch-template
[--dry-run | --no-dry-run]
[--client-token <value>]
[--launch-template-id <value>]
[--launch-template-name <value>]
[--default-version <value>]
[--cli-input-json | --cli-input-yaml]
[--generate-cli-skeleton <value>]

Options

--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 .

--client-token (string)

Unique, case-sensitive identifier you provide to ensure the idempotency of the request. For more information, see Ensuring idempotency .

Constraint: Maximum 128 ASCII characters.

--launch-template-id (string)

The ID of the launch template.

You must specify either the LaunchTemplateId or the LaunchTemplateName , but not both.

--launch-template-name (string)

The name of the launch template.

You must specify either the LaunchTemplateName or the LaunchTemplateId , but not both.

--default-version (string)

The version number of the launch template to set as the default version.

--cli-input-json | --cli-input-yaml (string) Reads arguments from the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton. If other arguments are provided on the command line, those 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. This may not be specified along with --cli-input-yaml.

--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. Similarly, if provided yaml-input it will print a sample input YAML that can be used with --cli-input-yaml. If provided with the value output, it validates the command inputs and returns a sample output JSON for that command. The generated JSON skeleton is not stable between versions of the AWS CLI and there are no backwards compatibility guarantees in the JSON skeleton generated.

See ‘aws help’ for descriptions of global parameters.

Examples

Note

To use the following examples, you must have the AWS CLI installed and configured. See the Getting started guide in the AWS CLI User Guide for more information.

Unless otherwise stated, all examples have unix-like quotation rules. These examples will need to be adapted to your terminal’s quoting rules. See Using quotation marks with strings in the AWS CLI User Guide .

To change the default launch template version

This example specifies version 2 of the specified launch template as the default version.
