This part of the Python Guestbook code walkthrough shows how to deploy the application to App Engine.
This page is part of a multi-page tutorial. To start from the beginning and see instructions for setting up, go to Creating a Guestbook.
Region ID
The REGION_ID is a code that Google assigns based on
the region you select when you create your app. Including
REGION_ID.r in App Engine URLs is optional for
existing apps and will soon be required for all new apps.
To ensure a smooth transition, we are slowly updating App Engine to use region IDs. If we haven't updated your Google Cloud project yet, you won't see a region ID for your app. Since the ID is optional for existing apps, you don't need to update URLs or make other changes once the region ID is available for your existing apps.
Learn more about region IDs.
Deploying the app to App Engine
To upload the guestbook app, run the following command from within the
appengine-guestbook-python directory of your application where the app.yaml
and index.yaml files are located:
gcloud app deploy app.yaml index.yaml
Optional flags:
- Include the
--projectflag to specify an alternate Cloud Console project ID to what you initialized as the default in thegcloudtool. Example:--project [YOUR_PROJECT_ID] - Include the
-vflag to specify a version ID, otherwise one is generated for you. Example:-v [YOUR_VERSION_ID]
The Datastore indexes
might take some time to generate before your application is available. If the
indexes are still in the process of being generated, you will receive a
NeedIndexError message when accessing your app. This is a transient error, so
try a little later if at first you receive this error.
To learn more about deploying your app from the command line, see Deploying a Python App.
Viewing your deployed application
To launch your browser and view the app at
https://PROJECT_ID.REGION_ID.r.appspot.com, run the following command:
gcloud app browse
