Roles that Grant Access to App Engine | App Engine standard environment for Java 8

Skip to main content Roles that Grant Access to App Engine

Stay organized with collections Save and categorize content based on your preferences.

Roles determine which services and actions are available to a user account or service account. The following types of roles grant access to App Engine:

Basic roles which apply to all services and resources in a project, including but not limited App Engine. For example, an account with the Editor role can change App Engine settings as well as Cloud Storage settings.
Predefined App Engine roles, which provide granular access to App Engine. Each service in your Google Cloud project provides its own predefined roles. For example, an account that only has the App Engine Deployer role can deploy App Engine apps but cannot view or create objects in Cloud Storage. Such an account would also need a specific Cloud Storage predefined role to create or view objects in Cloud Storage.
Custom roles, which provide granular access according to a list of permissions you specify.

You can use basic roles when you are working on smaller projects that have less complex needs. For more fine-tuned access controls, use predefined roles.

Basic roles

Basic roles apply to all services and resources in a project. For example, an account in the Editor role can change App Engine settings as well as Cloud Storage settings.

Role Google Cloud console permissions Tools permissions Owner Required to create App Engine applications. All viewer and editor privileges, plus the ability to view deployed source code, invite users, change user roles, and delete an application. Required to create App Engine applications. Can also deploy application code and update all configurations. Editor View application information and edit application settings. Deploy application code, update indexes/queues/crons. Viewer View application information. Request logs Predefined App Engine roles Role Permissions App Engine Admin

(roles/appengine.appAdmin)

The predefined roles for App Engine provide you with finer grained options for access control.

These roles only provide access to App Engine. If your project includes other services, such as Cloud Storage or Cloud SQL, you will need to assign additional roles to enable access to the other services.

Comparison of App Engine predefined roles

The following table provides a complete comparison of the capabilities of each predefined App Engine role.

Capability App Engine Admin App Engine Service Admin App Engine Deployer App Engine Viewer App Engine Code Viewer List all services, versions and instances Yes Yes Yes Yes Yes View all application, service, version, and instance settings Yes Yes Yes Yes Yes View runtime metrics such as resource usage, load information, and error information Yes Yes Yes Yes Yes View app source code No No No No Yes Deploy a new version of an app Yes, if you also grant the Service Account User role No Yes, if you also grant the Service Account User role No No Split or migrate traffic Yes Yes No^*** No No Start and stop a version Yes Yes No No No Delete a version Yes Yes Yes No No Delete an entire service Yes Yes No No No Use SSH to connect to a VM instance in the flexible environment Yes No No No No Shut down an instance Yes No No No No Disable and re-enable the App Engine application Yes No No No No Access handlers that have a login:admin restriction (first generation runtimes only) Yes No No No No Update dispatch rules Yes No No No No Update DoS settings Yes No No No No Update cron schedules No No No No No Update default cookie expiration Yes No No No No Update referrers Yes No No No No Update Email API Authorized Senders Yes No No No No Note: The predefined roles are enforced in the Google Cloud console, the Admin API, and other tooling that requires access, including the deployment commands.

For details about the specific IAM permissions that are granted by each role, see the Roles section of the Admin API.

Recommended role for application deployment

For an account that is responsible only for deploying new versions of an app, we recommend that you grant the following roles:

App Engine Deployer role (roles/appengine.deployer)
Service Account User role (roles/iam.serviceAccountUser)

The Service Account User role enables the account to impersonate the default App Engine service account during the deployment process.
If the account uses gcloud commands or other App Engine tooling to deploy, add these roles as well:
- Storage Object Admin (roles/storage.objectAdmin)
- Cloud Build Editor (roles/cloudbuild.builds.editor)

Note: If you have granted an account the App Engine Admin role, you don't need to grant it the App Engine Deployer role, because the Admin role holds the same relevant permissions as the Deployer role, along with additional administrative privileges. We recommend using the App Engine Deployer role for accounts that are responsible only for deploying new versions.

For details about how to grant the required permissions, see Creating a user account.

Separation of deployment and traffic routing duties

Many organizations prefer to separate the task of deploying an application version from the task of ramping up traffic to the newly created version, and to have these tasks done by different job functions. The App Engine Deployer and App Engine Service Admin roles provide this separation:

App Engine Deployer plus Service Account User roles - Accounts are limited to deploying new versions and deleting old versions that are not serving traffic. The account with these roles won't be able to configure traffic to any version nor change application-level settings such as dispatch rules or authentication domain.
App Engine Service Admin role - Accounts cannot deploy a new version of an app nor change application-level settings. However, those accounts have privileges to change the properties of existing services and versions, including changing which versions can serve traffic. The App Engine Service Admin role is ideal for an Operations/IT department that handles ramping up traffic to newly deployed versions.

Note: Accounts with the App Engine Deployer role can overwrite a version that is serving traffic by deploying a new version with the same name (using the --version flag). Limitations of the predefined roles

None of the App Engine predefined roles grant access to the following:

View and download application logs.
View Monitoring charts in the Google Cloud console.
Enable and Disable billing.
Run security scans in Cloud Security Scanner.
Access configuration or data stored in Datastore, Task Queues, Cloud Search or any other Cloud Platform storage product.
