Region ID
The REGION_ID is an abbreviated code that Google assigns
based on the region you select when you create your app. The code does not
correspond to a country or province, even though some region IDs may appear
similar to commonly used country and province codes. For apps created after
February 2020, REGION_ID.r is included in
App Engine URLs. For existing apps created before this date, the
region ID is optional in the URL.

Use the Google Cloud CLI to deploy your web service to App Engine.
Though this initial version of the web service doesn't have Firestore in Datastore mode (Datastore) or Firebase authentication, you can deploy it to App Engine at this stage to test and ensure that it works as expected.
Before you begin
If you have completed all the previous steps in this guide, skip this section. Otherwise, complete one of the following:
Start from Build a Python 3 App and complete all the steps leading up to this one.
If you already have a Google Cloud project, you can continue by downloading a copy of the web service:
Download the sample application repository using Git:
git clone https://github.com/GoogleCloudPlatform/python-docs-samplesAlternatively, you can download the sample as a zip file and then extract it.
Navigate to the directory that contains a copy of the files from the previous step:
cd python-docs-samples/appengine/standard_python3/building-an-app/building-an-app-1
Deploy your service
To deploy your web service, you run the
gcloud app deploy command from the root
directory of your project, where your app.yaml file is located:
gcloud app deploy
Each time that you deploy your web service, a new version of that app is created in App Engine. During deployment, a container image is created using the Cloud Build service, and then a copy is uploaded to Google Cloud Storage before it is run in App Engine.
For more information about deploying to App Engine, see Testing and Deploying Your App.
Viewing your service
To quickly launch your browser and access your web service at
https://PROJECT_ID.REGION_ID.r.appspot.com, enter the following
command:
gcloud app browse
Managing services and versions
You've just deployed a version of the web service to App Engine. Each
time that you deploy a version of your code, that version is created in a
service. The initial deployment to App Engine must be created in the
default service, but for subsequent deployments, you can
specify the name of your service in your app.yaml file.
You can update a service at any time by running the
gcloud app deploy command and deploying new versions to that service. Each
time that you update a service, traffic is automatically routed to the version
last deployed. However, you can include
gcloud flags to change the deploy command
behavior.
Use the Google Cloud console to manage and view the services and versions that you deploy to App Engine:
Use the Google Cloud console to view your App Engine services:
