Subject: [PATCH] vagrant: add ability to use drives in the VMs
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
When testing deployments of SDS, it is quite useful to get a Kubernetes
env with nodes having dedicated drives.
You can now enable this by setting: kube_node_instances_with_disks: true
Also you can chose the amount of drives per machine and their respective
size:
* kube_node_instances_with_disks_number: 10
* kube_node_instances_with_disks_size: "20G"
