This is from SO question: https://stackoverflow.com/questions/47335752/is-there-any-way-to-print-to-stdout-stderr-or-log-files-in-google-deployment-m

There seems to be no way to print to stdout from inside a Python template in Cloud Deployment Manager e.g.:

<def GenerateConfig(context):
  """Generates configuration of a VM."""
  print "Hello World"........
  and so on....>

<gcloud deployment-manager deployments create...>

"Hello World" will not be printed.

However, if I deliberately raise an error in my template, then I can see the stdout is captured in the traceback:

<ERROR: (gcloud.deployment-manager.deployments.create) Error in Operation [operation-1527510990084-56d435df457a0-37434418-54b86991]: errors:

Users need a way to debug/log while developing.
