- To create an external disk, we'll use the following command:
$ gcloud compute disks create --size 1GB mongo-disk \--zone us-east1-c

Navigate to /Chapter16/mysite-gke/db-deployment.yml:
apiVersion: apps/v1beta1 kind: Deployment metadata: name: mongo-deployment spec: replicas: 1 template: metadata: ...
