问题 When setting up the OS Login on one GCE instance I get a Permission denied message for a new user of the project. As per the Google Cloud documentation on OS Login, I've set metadata to enable-oslogin TRUE , and the permission for the user in the instance to roles/compute.osLogin , as there's no further Organization or service account required in this test case. Firewall rules are OK too. I've enabled the role Project Editor and it works, but I don't want the user to be an Editor nor a Viewer
