Like the title says I would like a flex environment to not be connected to the internet and only be reachable via a VPC. Is this possible?
The only way I found I could hide it is to enable the AppEngine firewall to block the traffic, but then I can't have other App Engine Containers that I want to be connected to the internet.
Also I would not like to add a compute engine that handles all traffic since it would cost more and remove the auto scaling of the app engines.
Let me know if this is confusing and would like more info.
