DESCRIPTION
gcloud init launches an interactive Getting Started workflow for the gcloud command-line tool. It performs the following setup steps:
Authorizes gcloud and other SDK tools to access Google Cloud Platform using your user account credentials, or from an account of your choosing whose credentials are already available.
Sets up a new or existing configuration.
Sets properties in that configuration, including the current project and optionally, the default Google Compute Engine region and zone you'd like to use.
