Always

1. create vpc network, subnets, and a firewall-rule to allow ssh access to the bastion host
2. create the bastion host, with setting a valid service-account and scopes of "https://www.googleapis.com/auth/cloud-platform"
3. scp pull secret to the bastion host
4. ssh to the bastion host (subsequent steps would be on the bastion host, except told explicitly)
5. get "oc", e.g. curl https://mirror2.openshift.com/pub/openshift-v4/clients/ocp/4.9.9/openshift-client-linux-4.9.9.tar.gz -o openshift-client-linux-4.9.9.tar.gz; tar zxvf openshift-client-linux-4.9.9.tar.gz
6. obtain the installation program
7. try "create install-config" of platform "gcp"
