-- Retrieves the configuration data of the specified instance. You can use
-- this data to create a launch template.
--
-- This action calls on other describe actions to get instance information.
-- Depending on your instance configuration, you may need to allow the
-- following actions in your IAM policy: @DescribeSpotInstanceRequests@,
-- @DescribeInstanceCreditSpecifications@, @DescribeVolumes@,
-- @DescribeInstanceAttribute@, and @DescribeElasticGpus@. Or, you can
-- allow @describe*@ depending on your instance requirements.
