Container-VM Image
Container-VM Image is a container-optimized OS image for the Google Cloud Platform (GCP). It is primarily for running Google services on GCP. Unlike the open preview version of container-vm, the new Container-VM Image is based on the open source ChromiumOS project, allowing us greater control over the build management, security compliance, and customizations for GCP.
