Creating an App for the App Engine Flexible Environment

App Engine is a fully managed, serverless platform for developing and hosting web applications at scale. This document describes how to create an application for the App Engine flexible environment.

Before you begin

Follow the Quickstart to install and setup Cloud Code.

Creating a new application

You can create a new application by using the new project wizard or by importing an existing project in Cloud Source Repositories.

Using the new project wizard

To create a new project, you can use the IntelliJ New Project wizard to generate a template application as the start for your own application.

Create a new project as follows:

  1. Choose File > New > Project to display the New Project dialog.

  2. Choose Java in the left panel.

  3. In the Additional Libraries and Frameworks section, check the Google App Engine box for your environment.

  4. If needed, select the Create app.yaml checkbox.

  5. Click Next.

  6. Enter a Project name.

  7. Enter a Project location if you do not want to keep the default.

  8. Update the fields in the More Settings section if you do not want to keep the defaults.

  9. Click Finish.

Checking out an existing project

You can check out your existing project in Cloud Source Repositories:

  1. Choose VCS > Checkout from Version Control > Google Cloud.

  2. Screenshot showing the navigation to the
Source Code checkout menu option.
  3. In the Clone from Google Cloud dialog, select the Cloud Project associated with your project.
  4. Screenshot showing the dialog to checkout
source code.
  5. Select your Cloud Repository.
  6. Select the Parent Directory.
  7. Enter the Directory Name.
  8. Click Clone.

Adding framework support

If you never added framework support to your application, IntelliJ IDEA prompts you to configure the framework after detecting that you opened an App Engine application.

  1. Right click the project.

  2. Choose Add Framework Support.

  3. Select the App Engine flexible checkbox.

    Alternatively, you can add App Engine framework support through the Cloud Code menu:

    1. Select Tools > Cloud Code > Add App Engine support > Google App Engine flexible.

    2. Select the module you want to add framework support to.

    3. Click OK.

  4. If needed, select the Create app.yaml checkbox.

  5. Click OK.

What's next

You can deploy your application to the App Engine flexible environment.
