Installing the command-line tools to configure GCP services

In this recipe, we will get the primary CLI for Google Cloud Platform, gcloud, installed so that we can configure GCP services:

1. Run the following command to download the gcloud CLI: 

$ curl https://sdk.cloud.google.com | bash

2. Initialize the SDK and follow the instructions given:

$ gcloud init

3. During the initialization, when asked, select either an existing project that you have permissions for or create a new project.
4. Enable the Compute Engine APIs for the project:

$ gcloud services enable compute.googleapis.com
Operation "operations/acf.07e3e23a-77a0-4fb3-8d30-ef20adb2986a" finished successfully.

5. Set a default zone:

$ gcloud config set compute/zone us-central1-a

6. Make sure you can start up a GCE instance from the command line:

$ gcloud compute instances create "devops-cookbook" \
--zone "us-central1-a" --machine-type "f1-micro"

7. Delete the test VM:

$ gcloud compute instances delete "devops-cookbook"

If all the commands are successful, you can provision your GKE cluster.
