Access Compute Engine through internal ip address from App Engine

[sujesh thekkepatt]

I have an app running in google app engine flexible environment. I also have a compute engine instance running my queue service(docker). Currently, I have exposed a public IP and through which I am connecting app engine and the instance. But I need to use the internal IP address and need to implement firewall rules. So whenever I use an internal IP address app engine can't connect to it. Any help appreciated.

Virtual Private Cloud (VPC) allows you to connect Compute Engine VMs with App Engine Flex apps via internal IPs subject to applicable network firewall rules.

I suggest you take a look at the VPC specifications, how to create and use the VPC networks.
