okd/roles/docker_storage_setup

docker_storage_setup

This role coverts docker to go from loopback to direct-lvm (the Red Hat recommended way to run docker).

It requires the block device to be already provisioned and attached to the host.

Notes:

• This is NOT idempotent. Conversion needs to be done for it to be idempotent
• This will remove /var/lib/docker!
• You will need to re-deploy docker images
