You create and manage App Engine applications using the Google Cloud Platform Console.
Once you have created a new project and registered a project ID for it
(which also serves as the application ID for your application), you
upload your application using
Note: Application IDs must begin with a letter. Once you register an application ID, you can delete it, but you can't re-register that same application ID after it has been deleted. You can skip these next steps if you don't want to register an ID at this time.
Registering the Application
You create and manage App Engine applications from the Cloud Platform Console at this URL:
Sign in to App Engine using your Google account. If you do not have a Google account, you can create a Google account with an email address and password.
Note: You may have already created a project using the Google Cloud Platform Console. If this is the case, you do not have to create a new application. Your project has a title and an ID. In the instructions that follow, the project title and ID can be used wherever an application title and ID are mentioned. They are the same thing.
To create a new application, click the "Create a Project" button. Follow the instructions to register a project ID, a name unique to this application.
If you elect to use the free appspot.com domain name, the full
URL for the application will be
You may also purchase a top-level domain name for your app, or use one that you
have already registered.
Note: You can specify that your new application should reside in the European Union, rather than the United States. Hosting applications in the European Union is especially useful if your application's users are closer to Europe than to the United States. There is less network latency and the End User Content will be stored at rest in the European Union. You must specify this location when you register the application; you cannot change it later. Click Show Advanced Options in the Create Project section to select a location option, either United States or European Union.
Uploading the Application
Then, upload your finished application to Google App Engine with the following command, providing
the project ID used during registration in the
goapp deploy -application <YOUR_PROJECT_ID> myapp/
If you see
compilation errors, fix the source and rerun
it won't launch (or update) your app until compilation is successful.
Checking Your Application State
After your application is uploaded,
its Datastore Indexes
will be automatically generated. This operation may take some time, and any visitors
to your site will receive a
DatastoreNeedIndexException until the indexes have been
built. You can monitor the progress of the operation by visiting the
Cloud Platform Console, selecting your application, and then
selecting the Storage, Cloud Datastore, Indexes link.
Accessing Your Application
You can now see your application running on App Engine. If you set up a free appspot.com domain name, the URL for your website begins with your application ID:
