Hi,  I'm new to clusterdock and trying to get started on Mac Sierra 10.12.16 with Docker Version 17.09.0-ce-mac35.   Is there a trick to getting it running in this env?  Below is what I'm seeing     clusterdock_run ./bin/start_cluster cdh INFO:clusterdock.cluster:Network (cluster) not present, creating it...
