-- * 'uceState' - The state of the compute environment. Compute environments in the @ENABLED@ state can accept jobs from a queue and scale in or out automatically based on the workload demand of its associated queues.
--
-- * 'uceComputeResources' - Details of the compute resources managed by the compute environment. Required for a managed compute environment.
--
-- * 'uceServiceRole' - The full Amazon Resource Name (ARN) of the IAM role that allows AWS Batch to make calls to other AWS services on your behalf. If your specified role has a path other than @/@ , then you must either specify the full role ARN (this is recommended) or prefix the role name with the path.
--
-- * 'uceComputeEnvironment' - The name or full Amazon Resource Name (ARN) of the compute environment to update.
