    • Method Detail

      • state

        public final InstanceMetadataState state()

        The state of the metadata option changes.

        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.

        If the service returns an enum value that is not available in the current SDK version, state will return InstanceMetadataState.UNKNOWN_TO_SDK_VERSION. The raw value returned by the service is available from stateAsString().

        Returns:
        The state of the metadata option changes.

        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.

      • httpTokens

        public final HttpTokens 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.

        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.

        If the service returns an enum value that is not available in the current SDK version, httpTokens will return HttpTokens.UNKNOWN_TO_SDK_VERSION. The raw value returned by the service is available from httpTokensAsString().

        Returns:
