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 deployto use the service. To return to the default behavior, use the commandgcloud config set app/use_cloud_build False.
