Automatic merge from submit-queue (batch tested with PRs 51590, 48217, 51209, 51575, 48627) FlexVolume setup script for COS instance using mounting utility image in GCR. **What this PR does / why we need it**: This scripts automates FlexVolume installation for a single COS instance. Users need to pre-pack their drivers and mount utilities in a Docker image and upload it to GCR. For each FlexVolume plugin, the script places a driver wrapper in a writable and executable location. The wrapper calls commands from the actual driver but in a chroot environment, so that mount utilities from the image can be used. I'm working on a script that automatically executes this on all instances. Will be in a separate PR. **Which issue this PR fixes** *(optional, in `fixes #<issue number>(, fixes #<issue_number>, ...)` format, will close that issue when PR gets merged)*: fixes #48626 ```release-note NONE ``` /cc @gmarek @chakri-nelluri /assign @saad-ali @msau42 /sig storage /release-note-none
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.
