Use theGoogle Cloud CLI todeploy your web service to App Engine.

Though this initial version of the web service doesn't haveFirestore in Datastore mode (Datastore) or Firebase authentication,you can deploy it to App Engine at this stage to test and ensure thatit 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 fromBuild a Python 3 Appand complete all the steps leading up to this one.

• If you already have aGoogle Cloud project,you can continue by downloading a copy of the web service:

  1. Download the sample application repository usingGit:

     gitclonehttps://github.com/GoogleCloudPlatform/python-docs-samples

     Alternatively, you candownload the sample as a zip file and then extract it.

  2. Navigate to the directory that contains a copy of the files from theprevious step:

     cdpython-docs-samples/appengine/standard_python3/building-an-app/building-an-app-1

Deploy your service

To deploy your web service, you run thegcloud app deploy command from the rootdirectory of your project, where yourapp.yaml file is located:

gcloudappdeploy

Each time that you deploy your web service, a newversion of thatapp is created in App Engine. During deployment, a container image iscreated using theCloud Build service, andthen a copy is uploaded to Google Cloud Storage before it is run inApp Engine.

For more information about deploying to App Engine, seeTesting and Deploying Your App.

Viewing your service

To quickly launch your browser and access your web service athttps://PROJECT_ID.REGION_ID.r.appspot.com, enter the followingcommand:

gcloudappbrowse

Managing services and versions

You've just deployed a version of the web service to App Engine. Eachtime that you deploy a version of your code, that version is created in aservice. The initial deployment to App Engine must be created in thedefault service, but for subsequent deployments, you canspecify the name of your service in yourapp.yaml file.

You can update a service at any time by running thegcloud app deploy command and deploying new versions to that service. Eachtime that you update a service, traffic is automatically routed to the versionlast deployed. However, you can includegcloud flags to change the deploy commandbehavior.

Use the Google Cloud console to manage and view the services and versions thatyou deploy toApp Engine:

• Use the Google Cloud console to view your App Engine services:

  Go to the services page

• Use the Google Cloud console to view your versions:

  Go to the versions page

For more information about the multi-service design pattern, seeAn Overview of App Engine.To learn how to send requests to specific services and versions, seeSplitting Traffic.

Next steps

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