When passing InstanceMetadataOptionsRequest as input to an Aws::Client method, you can use a vanilla Hash:

{
  http_tokens: "optional",   http_put_response_hop_limit: 1,
  http_endpoint: "disabled", }

The metadata options for the instance.

Returned by:

• RunInstancesRequest#metadata_options

• #http_endpoint ⇒ String

  This parameter enables or disables the HTTP metadata endpoint on your instances.

• #http_put_response_hop_limit ⇒ Integer

  The desired HTTP PUT response hop limit for instance metadata requests.

• #http_tokens ⇒ String

  The state of token usage for your instance metadata requests.

This parameter 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.

Possible values:

• disabled
• enabled

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

The state of token usage for your instance metadata requests. If the parameter is not specified in the request, the default state is optional.

If the state is optional, you can choose to retrieve instance metadata with or without a signed token header on your request. If you retrieve the IAM role credentials without a token, the version 1.0 role credentials are returned. If you retrieve the IAM role credentials using a valid signed token, the version 2.0 role credentials are returned.

If the state is required, you must send a signed token header with any instance metadata retrieval requests. In this state, retrieving the IAM role credentials always returns the version 2.0 credentials; the version 1.0 credentials are not available.

Possible values:

• optional
• required
