I have two GCP projects, projectA and projectB. In projectB, I have a machine image B-machine-image. My goal was to make a copy of the machine image in projectA. But since there is no way to copy the machine image from projectB to projectA directly, I thought I can create a instance in projectA using the machine image in projectB, then use the new instance in projectA to create a machine image locally.
I found a Google Doc for this: https://cloud.google.com/compute/docs/machine-images/create-instance-from-machine-image and followed the steps to first grant the service account in projectA admin role to the machine image B-machine-image in projectB, then run the command to make the instance like:
gcloud beta compute instances create my-new-instance --project=projectA --zone us-central1-b --source-machine-image projects/projectB/global/machineImages/B-machine-image --service-account email@example.com
and I am getting the error:
ERROR: (gcloud.beta.compute.instances.create) Could not fetch resource:
- Invalid value for field 'resource.networkInterfaces.network': 'projects/123456789000/global/networks/projectB-vpc'. The referenced network resource cannot be found.
In projectB, I do have a VPC called projectB-vpc.
What I do not understand is that in "projects/123456789000/global/networks/projectB-vpc", 123456789000 seems is for projectA as it is part of the email for projectA service account, while projectB-vpc is for projectB. In my command I have "projects/projectB/....", why the command replaced "projectB" with 123456789000?
Any idea where did I do wrong?
