Ravel and containerd

Ravel use containerd to manages images and to build virtual machines rootfs. Ravel use containerd configured with devmapper storage driver and a thinpool to build virtual machines rootfs. You need to provide to containerd the thinpool configuration.

For development

1. Create a backing file for the loopback device

$ fallocate -l 30G ./tmp/vg-ravel.img

2. Run the script

You can use this script to automatically setup the thinpool like this:

$ ./scripts/setup-dev-thinpool.sh ./tmp/vg-ravel.img ravel

Alternatively follow the documentation of containerd.

For production

Please follow the production documentation provided by docker here.
