EC2.Instance.metadata_options#

  • (dict) –

    The metadata options for the instance.

    • State (string) –

      The state of the metadata option changes.

      pending - The metadata options are being updated and the instance is not ready to process metadata traffic with the new selection.

      applied - The metadata options have been successfully applied on the instance.

    • HttpTokens (string) –

      IMDSv2 uses token-backed sessions. Indicates whether the use of HTTP tokens is optional (in other words, indicates whether the use of IMDSv2 is optional) or required (in other words, indicates whether the use of IMDSv2 is 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

    • HttpPutResponseHopLimit (integer) –

      The desired HTTP PUT response hop limit for instance metadata requests. The larger the number, the further instance metadata requests can travel.

    • HttpEndpoint (string) –
