InstanceMetadataOptions - Amazon Lightsail

InstanceMetadataOptions

The metadata options for the instance.

Contents

httpEndpoint

Indicates whether the HTTP metadata endpoint on your instances is enabled or disabled.

If the value is disabled, you cannot access your instance metadata.

Type: String

Valid Values: disabled | enabled

Required: No

httpProtocolIpv6

Indicates whether the IPv6 endpoint for the instance metadata service is enabled or disabled.

Type: String

Valid Values: disabled | enabled

Required: No

httpPutResponseHopLimit

The desired HTTP PUT response hop limit for instance metadata requests. A larger number means that the instance metadata requests can travel farther.

Type: Integer

Required: No

httpTokens

The state of token usage for your instance metadata requests.

If the state is optional, you can choose whether to retrieve instance metadata with 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 by 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 all instance metadata retrieval requests. In this state, retrieving the IAM role credential always returns the version 2.0 credentials. The version 1.0 credentials are not available.

Important

Not all instance blueprints in Lightsail support version 2.0 credentials. Use the MetadataNoToken instance metric to track the number of calls to the instance metadata service that are using version 1.0 credentials. For more information, see Viewing instance metrics in Amazon Lightsail in the Amazon Lightsail Developer Guide.

Type: String

Valid Values: optional | required

Required: No

The following states are possible:

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

  • applied - The metadata options have been successfully applied to the instance.

Type: String

Valid Values: pending | applied

Required: No
