Description Antonio Escalera 2020-03-05 16:05:39 UTC 
Description of problem:

In GCP, it is common to have one project with all of the networks, and share them to VPCs in other projects. 
UPI with this topology currently fails when creating manifests.
We need to be able to support shared VPC networking, as this is the current best practices recommendation from Google.

https://cloud.google.com/vpc/docs/shared-vpc#shared_vpc_networks

Version:
4.3.2

How reproducible:

100%

Steps to Reproduce:
1. Create project with networks
2. Share networks to VPC in different project
3. Try to run the OpenShift installer in that different project

Actual results:

$ openshift-install create manifests
FATAL failed to fetch Master Machines: failed to load asset "Install Config": platform.gcp.network: Invalid value: "paas-ops-01": failed to get network paas-ops-01: Get https://www.googleapis.com/compute/v1/projects/xxxxx-paas-ops/global/networks/paas-ops-01?alt=json&prettyPrint=false: context canceled

Expected results:

Manifests are created successfully

We don't support Shared VPC. This is not a bug.
