gce - create or terminate GCE instances¶

# Basic provisioning example.  Create a single Debian 8 instance in the
# us-central1-a Zone of the n1-standard-1 machine type.
# Create multiple instances by specifying multiple names, separated by
# commas in the instance_names field
# (e.g. my-test-instance1,my-test-instance2)
