Note that your GCP identity is case sensitive but `gcloud info` as of Google Cloud SDK 221.0.0 is not. This means that if your IAM member contains capital letters, the above one-liner may not work for you. If you have 403 forbidden responses after running the above command and `kubectl apply -f examples/standard`, check the IAM member associated with your account at https://console.cloud.google.com/iam-admin/iam?project=PROJECT_ID. If it contains capital letters, you may need to set the --user flag in the command above to the case-sensitive role listed at https://console.cloud.google.com/iam-admin/iam?project=PROJECT_ID.

After running the above, if you see `Clusterrolebinding "cluster-admin-binding" created`, then you are able to continue with the setup of this service.
