virt-disk-operator

A Kubernetes operator for creating virtual disk devices. This is primarily useful for testing distributed storage systems.

Features

• Based on Linux NBD (Network Block Device).
• Can be run locally (eg. KinD) including on Docker Desktop for Mac (using containerized udev).
• Thin provisioning (eg. virtual disks only take up as much space as they need).
• LVM2 logical volume support.
• LUKS encryption support.
