Method Detail

getHttpEndpoint

default java.lang.String getHttpEndpoint()

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.

getHttpProtocolIpv6

default java.lang.String getHttpProtocolIpv6()

Enables or disables the IPv6 endpoint for the instance metadata service.

Default: disabled

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

Possible values: Integers from 1 to 64

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.

getInstanceMetadataTags

default java.lang.String getInstanceMetadataTags()

Set to `enabled` to allow access to instance tags from the instance metadata.

Set to disabled to turn off access to instance tags from the instance metadata. For more information, see Work with instance tags using the instance metadata .

Default: disabled

builder

static CfnLaunchTemplate.MetadataOptionsProperty.Builder builder()

Returns:

a CfnLaunchTemplate.MetadataOptionsProperty.Builder of CfnLaunchTemplate.MetadataOptionsProperty
