Google container registry (https://cloud.google.com/container-registry/) is a part of the GCP. Similar to AWS, having a GCP account is required, as well as Cloud SDK (https://cloud.google.com/sdk/), which is the command-line interface in GCP. More details about GCP will be described in Chapter 7, Building Kubernetes on GCP. 

On GCP, we'll just need to create a project and enable billing and the container registry API for our project. Otherwise, any operation in gcloud will display an error:

$ gcloud container images list 
ERROR: (gcloud.container.images.list) Bad status during token exchange: 403 

In order to enable billing and container registry API, visit the GCP web console (https://console.cloud.google.com), navigate to the billing page and container registry page, then just enable those. Once activation is done, you can use the gcloud container command:

$ gcloud container images list 
Listed 0 items.
