All the cloud providers offer a storage class for k8s. The storage class allows you to tell k8s that you want a persistent volume (PV) and it will make API calls to the cloud provider to get you a block storage device. You can tell k8s you want to use that PV in your pod and k8s will automatically mount the block storage to the worker node that your pod lives on and makes it available to the pod.

OP uses Longhorn which is a whole other thing that I've only read about.

For at home you can use other storage classes like ceph, NFS, etc.
