#http_protocol_ipv_6 ⇒ String

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

Default: ‘disabled`

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)

  :http_protocol_ipv_6,
  :instance_metadata_tags)
  SENSITIVE = []
  include Aws::Structure
end

#http_tokens ⇒ String

Indicates whether IMDSv2 is required.

• ‘optional` - IMDSv2 is optional. You can choose whether to send a session token in your instance metadata retrieval requests. If you retrieve IAM role credentials without a session token, you receive the IMDSv1 role credentials. If you retrieve IAM role credentials using a valid session token, you receive the IMDSv2 role credentials.

• ‘required` - IMDSv2 is required. You must send a session token in your instance metadata retrieval requests. With this option, retrieving the IAM role credentials always returns IMDSv2 credentials; IMDSv1 credentials are not available.

Default: If the value of ‘ImdsSupport` for the Amazon Machine Image (AMI) for your instance is `v2.0`, the default is `required`.

Returns:

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`
