Method Detail

getHttpEndpoint

@Stability(value=Stable)
 @Nullable
default 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

@Stability(value=Stable)
 @Nullable
default 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

@Stability(value=Stable)
 @Nullable
default 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

@Stability(value=Stable)
static CfnLaunchConfiguration.MetadataOptionsProperty.Builder builder()

Returns:

a CfnLaunchConfiguration.MetadataOptionsProperty.Builder of CfnLaunchConfiguration.MetadataOptionsProperty
