`MetadataOptions` is a property of [AWS::AutoScaling::LaunchConfiguration](https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-properties-as-launchconfig.html) that describes metadata options for the instances.

For more information, see Configure the instance metadata options in the Amazon EC2 Auto Scaling User Guide .

Example:

 // The code below shows an example of how to instantiate this type.
 // The values are placeholders you should change.
 import software.amazon.awscdk.services.autoscaling.*;

Method Detail

getHttpEndpoint

default java.lang.String getHttpEndpoint()

This parameter enables or disables the HTTP metadata endpoint on your instances.

If the parameter is not specified, the default state is enabled .

If you specify a value of disabled , you will not be able to access your instance metadata.

getHttpPutResponseHopLimit

default java.lang.Number getHttpPutResponseHopLimit()

The desired HTTP PUT response hop limit for instance metadata requests.

The larger the number, the further instance metadata requests can travel.

Default: 1

getHttpTokens

default java.lang.String getHttpTokens()

The state of token usage for your instance metadata requests.

If the parameter is not specified in the request, the default state is optional .

If the state is optional , you can choose to retrieve instance metadata with or without a signed token header on your request. If you retrieve the IAM role credentials without a token, the version 1.0 role credentials are returned. If you retrieve the IAM role credentials using a valid signed token, the version 2.0 role credentials are returned.

If the state is required , you must send a signed token header with any instance metadata retrieval requests. In this state, retrieving the IAM role credentials always returns the version 2.0 credentials; the version 1.0 credentials are not available.

builder

static CfnLaunchConfiguration.MetadataOptionsProperty.Builder builder()

Returns:

a CfnLaunchConfiguration.MetadataOptionsProperty.Builder of CfnLaunchConfiguration.MetadataOptionsProperty
