Deploy hangs for Managed VM's - hard to see why

Issue running command [gcloud preview app deploy].

What steps will reproduce the problem?

What is the expected output? What do you see instead?

this is our dockerfile. Maybe a config error but this exact dockerfile was used 
2 months back or so and worked fine. now we cannot deploy anymore.
