gcloud tool of the Cloud SDK to
deploy your web service to App Engine.
Though this initial version of the web service doesn't have Cloud 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 Building a Python 3.7 App and complete all the steps leading up to this one.
If you already have a GCP 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-samples
Alternatively, 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:
Deploying 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

Tip: If you would like to change the URL of your web service to something other
than the default
appspot.com URL, you can
add a custom domain.
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
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

Now that you have a Python 3.7 service running on App Engine, you're ready to learn how to handle data with Cloud Datastore.
