#http_protocol_ipv_6 ⇒ String

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

end

#http_put_response_hop_limit ⇒ Integer

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

Returns:

• (Integer)

  SENSITIVE = []
  include Aws::Structure
end

#http_tokens ⇒ String

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`

Returns:

• (String)

end

#instance_metadata_tags ⇒ String

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`
