Deployments for new projects might be impacted from the following changes to org policies:
- Starting in May 2024, Google Cloud enforces secure-by-default organization policies for all organization resources. This policy
prevents App Engine from granting the
Editor
role to the App Engine default services accounts by default. - Starting in June 2024, Cloud Build has changed the default behavior for how Cloud Build uses service accounts in new projects. This change is detailed in Cloud Build Service Account Change. As a result of this change, new projects deploying versions for the first time may be using the default App Engine service account with insufficient permissions for deploying versions.
If you are impacted by this change, you can do the following:
- Review the Cloud Build guidance on changes to the default service account and opt out of these changes.
- Grant the Editor role to the App Engine default service account.

App Engine is changing the URLs that you use to send requests to your apps. URLs now include a region ID to help Google route your requests more efficiently and reliably. For example, an app can receive requests at https://PROJECT_ID.REGION_ID.r.appspot.com
. This new URL is optional for existing apps and is provided 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.

- App Engine Managed VMs is renamed to App Engine flexible environment.
February 03, 2016
Container construction choices for Managed VMs
The
gcloud preview app deploy
(andmvn gcloud:deploy
) commands upload your artifacts to our servers and build a container to deploy your app to the Managed VM environment.There are two mechanisms for building the container image remotely. The default behavior is to build the container on a transient Compute Engine Virtual Machine which has Docker installed. Alternatively, you can use the Cloud Build service, which is in Beta. To use the Cloud Build service, follow these steps:
- Activate the Cloud Build API for your project.
- Use the command
gcloud config set app/use_cloud_build True
. This will cause all invocations ofgcloud preview app deploy
to use the service. To return to the default behavior, use the commandgcloud config set app/use_cloud_build False
.
