Description Abhinav Dahiya 2019-12-11 21:37:23 UTC 
Description of problem:
Based on https://cloud.google.com/resource-manager/reference/rest/Shared.Types/Binding

The members values can be:
```
deleted:serviceAccount:{emailid}?uid={uniqueid}: An email address (plus unique identifier) representing a service account that has been recently deleted. For example, my-other-app.com?uid=123456789012345678901. If the service account is undeleted, this value reverts to serviceAccount:{emailid} and the undeleted service account retains the role in the binding.
```

this looks like a new addition to the API since the archive from Oct 26, 2019 doesn't have these value type. see https://web.archive.org/web/20181026092140/https://cloud.google.com/resource-manager/reference/rest/Shared.Types/Binding

Also it doesn't look like the API is being consistent with the result as two consecutive requests are returning different responses :P

The installer destroy skips over these `deleted:` prefixed bindings.
Comment 2 Yang Yang 2019-12-25 07:55:36 UTC 
Verified with payload 4.4.0-0.nightly-2019-12-20-210709

Steps of verification as below:

1. Get the service accounts after the cluster setup
# gcloud projects get-iam-policy openshift-qe --format json | grep "yy44ip"
        "serviceAccount:yy44ip-dkcbh-m.gserviceaccount.com",
        "serviceAccount:yy44ip-dkcbh-openshift-m-vsn6d.gserviceaccount.com",
        "serviceAccount:yy44ip-dkcbh-m.gserviceaccount.com",
        "serviceAccount:yy44ip-dkcbh-m.gserviceaccount.com",
        "serviceAccount:yy44ip-dkcbh-w.gserviceaccount.com",
        "serviceAccount:yy44ip-dkcbh-openshift-i-xwv4t.gserviceaccount.com",
        "serviceAccount:yy44ip-dkcbh-m.gserviceaccount.com",
        "serviceAccount:yy44ip-dkcbh-openshift-i-2g9md.gserviceaccount.com",
        "serviceAccount:yy44ip-dkcbh-openshift-m-vsn6d.gserviceaccount.com",
        "serviceAccount:yy44ip-dkcbh-m.gserviceaccount.com",
        "serviceAccount:yy44ip-dkcbh-openshift-i-2g9md.gserviceaccount.com",
        "serviceAccount:yy44ip-dkcbh-w.gserviceaccount.com",


2. Get the service accounts after the cluster is destroyed

# gcloud projects get-iam-policy openshift-qe --format json | grep "yy44ip"
No output
