This directory contains scripts to run TopoLVM in a demonstration environment.
It uses kind to run Kubernetes
and loopback block devices to run lvmd
.
You can try to use TopoLVM with a specific tag as follows. The demonstration is not guaranteed to work correctly with the main branch.
$ git checkout topolvm-chart-v15.1.1
To start the demonstration environment, run the following commands:
$ make setup
$ make run
LVM logical volumes will be created and bound with a PersistentVolumeClaim as follows:
$ kubectl get pvc
NAME STATUS VOLUME CAPACITY ACCESS MODES STORAGECLASS AGE
