  • Container construction choices for Managed VMs

    The gcloud preview app deploy (and mvn 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 Container Builder service, which is in Beta. To use the Container Builder service, follow these steps:

    1. Activate the Container Builder API for your project.
    2. Use the command gcloud config set app/use_cloud_build True. This will cause all invocations of gcloud preview app deploy to use the service. To return to the default behavior, use the command gcloud config set app/use_cloud_build False.
