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()

IMDSv2 uses token-backed sessions.

Set the use of HTTP tokens to optional (in other words, set the use of IMDSv2 to optional ) or required (in other words, set the use of IMDSv2 to required ).

• optional - When IMDSv2 is optional, you can choose to retrieve instance metadata with or without a session token in your request. If you retrieve the IAM role credentials without a token, the IMDSv1 role credentials are returned. If you retrieve the IAM role credentials using a valid session token, the IMDSv2 role credentials are returned.
• required - When IMDSv2 is required, you must send a session token with any instance metadata retrieval requests. In this state, retrieving the IAM role credentials always returns IMDSv2 credentials; IMDSv1 credentials are not available.

Default: optional

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
