Getting ready

The following are the initial setup verification steps and network creation to be carried out before the recipe can be executed:

1. Create or select a GCP project.
2. Enable billing and enable the default APIs (some APIs such as BigQuery, storage, monitoring, and a few others are enabled automatically).
3. We'll create a VPC network called alpha. The following command assumes that you...
