Ghost Blog on the Google Kubernetes Engine
#The Compute Engine API has be enabled for the VPC subnet creation.
gcloud services enable compute.googleapis.com
#This enables the GKE API
gcloud services enable container.googleapis.com
#This enables the Google Cloud SQL Admin API
gcloud services enable sqladmin.googleapis.com
#This enables the Google Cloud SQL API
gcloud services enable sql-component.googleapis.com
#This may not be needed since the ghost blog container is hosted in DockerHub
#gcloud services enable containerregistry.googleapis.com
This creates the VPC network, VPC subnets, the Cloud NAT and Router and the GKE cluster

Additional steps for a production, highly available install of Ghost Blog. Apparently, the first Google result yields the discussion at https://forum.ghost.org/t/making-ghost-highly-available-and-scalable/1633/2 which I had participated in a few years ago, so I'm not sure if Ghost Blog has progressed so that it can be horizontally scaled.

NOTE: 1024 GB is the mimimum capacity for a FileStore instance. Monthly cost is more than $200 a month, so this is an expensive option.
