Populate Artifact Registry with an image of the sample application

1. In the Google Cloud console, open Cloud Shell.

   Open Cloud Shell

2. In Cloud Shell Editor, use the following command to clone the repository with the sample application code from GitHub:

    cloudshell_open  
   --repo_url  
    \
