Thanks for fixing my typo!
There is a way to change the OS type which is to pass the desired configuration file by the -P option. I've implement the mapping in gradle.
This remind me that the usage is somehow vague. So I reorganized the message in gradle tasks:
docker-provisioner - Provision a Bigtop cluster on Docker container(s). Default to CentOS and 1 node.
Create a 3 node cluster:
$ ./gradlew -Pnum_instances=3 docker-provisioner
Run smoke tests on 3 node cluster:
$ ./gradlew -Pnum_instances=3 -Prun_smoke_tests=true docker-provisioner
Specify configuration file (located in bigtop-deploy/vm/vagrant-puppet-docker/):
$ ./gradlew -Pconfig=vagrantconfig_debian.yaml docker-provisioner
docker-provisioner-destroy - Destroy provisioned Bigtop Docker cluster
docker-provisioner-ssh - Show ssh command to get in to the provisioned container
docker-provisioner-status - Show status of Bigtop Docker cluster
D you think this one better?
