This page walks you through deploying an App Engine standard or flexible environment application and securing it with Identity-Aware Proxy (IAP). The quickstart includes sample code for an App Engine standard environment web app that verifies a logged-in user's name. This quickstart uses Cloud Shell to clone and deploy the sample application. You can use this quickstart to enable IAP for your own App Engine standard environment or App Engine flexible environment app.

Before you begin
-
Sign in to your Google Account.
If you don't already have one, sign up for a new account.
-
In the Google Cloud Console, on the project selector page, select or create a Google Cloud project.
-
Projeniz için faturalandırmanın etkinleştirildiğinden emin olun.
Starting Cloud Shell
-
Click Activate Cloud Shell at the top of the
console window.
A Cloud Shell session opens inside a new frame at the bottom of the console and displays a command-line prompt. It can take a few seconds for the shell session to be initialized.
-
Enter the following in Cloud Shell to display the project IDs for your
projects:
gcloud projects list
-
Run the following command to set the default project, where
YOUR-PROJECT-ID
is the project ID you want to use for this quickstart:gcloud config set project YOUR-PROJECT-ID
Getting the sample code
Enter the following command in Cloud Shell to get the sample application:
git clone https://github.com/GoogleCloudPlatform/python-docs-samples.git
Change to the directory that contains the sample code:
cd python-docs-samples/appengine/standard/users/
Deploying the application
-
Use
gcloud
to deploy the application to App Engine:gcloud app deploy
-
The
target url:
is displayed in the formathttps://YOUR_PROJECT_ID.appspot.com
. To access your application, navigate to that URL in your web browser.
Enabling IAP
Selecting a project
-
Go to the
Identity-Aware Proxy
page.
Go to the Identity-Aware Proxy page - If you don't already have an active project, you'll be prompted to select the project you want to secure with IAP. Select the project to which you deployed the sample application.
Configuring the OAuth consent screen
If you haven't configured your project's OAuth consent screen, you'll be prompted to do so. An email address and product name are required for the OAuth consent screen.
-
Go to the OAuth consent screen.
Configure consent screen - Under Support email, select the email address you want to display as a public contact. This email address must be your email address, or a Google Group you own.
- Enter the Application name you want to display.
- Add any optional details you'd like.
- Click Save.
To change information on the OAuth consent screen later, such as the product name or email address, repeat the preceding steps to configure the consent screen.
Setting up IAP access
- Go to the Identity-Aware Proxy page.
Go to the Identity-Aware Proxy page - Select the resource you wish to modify by checking the box to its left. On the right side panel, click Add Member.
-
In the Add members dialog, add the email
addresses of groups or individuals to whom you want to grant the
IAP-secured Web App User role for the project.
The following kinds of accounts can be members:
- Google Account: user@gmail.com
- Google Group: admins@googlegroups.com
- Service account: server@example.gserviceaccount.com
- G Suite domain: example.com
Make sure to add a Google Account that you have access to.
- When you're finished adding members, click Add.
Turning on IAP
-
On the Identity-Aware Proxy page, under
HTTPS Resources, find the App Engine app you want to
restrict access to. The Published column shows the URL of
the app. To turn on IAP for the app,
- To enable IAP, you need the
appengine.applications.update
,clientauthconfig.clients.create
, andclientauthconfig.clients.getWithSecret
permissions. These permissions are granted by roles, such as the Project Editor role. To learn more, see Managing access to IAP-secured resources.
- To enable IAP, you need the
- To confirm that you want IAP to secure the application, click Turn On in the Turn on IAP window that appears. After you turn it on, IAP requires login credentials for all connections to your application.
Test Access
Access the app URL from a Google account that you added to IAP with the IAP-secured Web App User role as described above. You should have unrestricted access to the app.
Use an incognito window in Chrome to access the app and sign in when prompted. If you try to access the app with an account that isn't authorized with the IAP-secured Web App User role, you'll see a message saying that you don't have access.
