I use MAAS for bare metal and inventory management. I am trying to provision half of my machines as Harvester nodes and the rest as Rancher for RKE nodes for Kubernetes. Plan is to integrate them both together. I am able to install Rancher on the MAAS provisioned Ubuntu OS. I am having challenges to install Harvester in MAAS environment as it requires ISO or USB option and could not implement iPXE with MAAS without an image. Any suggestions?
