get-launch-template-data

Description

Retrieves the configuration data of the specified instance. You can use this data to create a launch template.

This action calls on other describe actions to get instance information. Depending on your instance configuration, you may need to allow the following actions in your IAM policy: DescribeSpotInstanceRequests, DescribeInstanceCreditSpecifications, DescribeVolumes, DescribeInstanceAttribute, and DescribeElasticGpus. Or, you can allow describe* depending on your instance requirements.

See ‘aws help’ for descriptions of global parameters.

Synopsis

  get-launch-template-data
[--dry-run | --no-dry-run]
--instance-id <value>
[--cli-input-json | --cli-input-yaml]
[--generate-cli-skeleton <value>]
[--cli-auto-prompt <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 .

--instance-id (string)

The ID of the instance.

--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.

--cli-auto-prompt (boolean) Automatically prompt for CLI input parameters.

See ‘aws help’ for descriptions of global parameters.

Examples

To get instance data for a launch template

This example gets data about the specified instance and uses the --query option to return the contents in LaunchTemplateData. You can use the output as a base to create a new launch template or launch template version.

Command:

aws ec2 get-launch-template-data --instance-id i-0123d646e8048babc --query 'LaunchTemplateData'
