A docker image to initialize RAID array of local SSDs on a Google Cloud's Kubernetes platform.
This image must be used with the --privileged flag (securityContext: { privileged: true } in Kubernetes pod definition)
The init_raid.sh script un-mounts all ssd0, ssd1, ..., removes empty /mnt/disks/ssd* directories,
and creates the RAID array as described in the Google's Local SSDs docs
The image is based on the Google's startup-script image.
