The InstanceMetadataOptionsRequest type exposes the following members



Public Property HttpEndpoint Amazon.EC2.InstanceMetadataEndpointState

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

Public Property HttpPutResponseHopLimit System.Int32

Gets and sets the property HttpPutResponseHopLimit.

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

Public Property HttpTokens Amazon.EC2.HttpTokensState

Gets and sets the property HttpTokens.

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

Public Property InstanceMetadataTags Amazon.EC2.InstanceMetadataTagsState

Gets and sets the property InstanceMetadataTags.

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.
