VDO on Kubernetes
Correct, it's not directly supported by Kubernetes but you can always manage your VDO modules and volumes at the host level. For example, mount the volumes under /mnt/vdo0 and then use them in a container with the HostPath volume option.
You can also, for example, specify a VDO volume as the main graph directory for your docker daemon with something like /usr/bin/dockerd -g /mnt/vdo0 That will make your images and your non-external volume container storage stored in that directory.
