If the file does not exist we will generate it as normal. If the file exists we will remove the old admin password before adding the "new" one. (Turns in to a no-op if the password exists). This did not work properly before because we were replacing by key, where the key was the password. New password would not match and so not replace the old password. Added a METADATA_CLOBBERS_CONFIG flag METADATA_CLOBBERS_CONFIG controls if we consider the values on disk or in metadata to be the canonical source of truth. Currently defaulting to false for GCE and forcing to true for GKE. Added handling for older forms of the basic_auth.csv file. Fixed comment to reflect new METADATA_CLOBBERS_CONFIG var.
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.
