[lxc-users] Kubernetes Storage Provisioning using LXD

[Eric]

That's is what I've also been trying to do

Kubernetes has a list of supported persistent volume types, of which the
only one's that aren't cloud-based that I've tried are NFS, CephFS,
Glusterfs, and HostPath

https://kubernetes.io/docs/user-guide/persistent-volumes/#types-of-persistent-volumes

With LXC + ZFS you can't:

- provide a raw block device (/dev/sad) to heketi, or a loopback device
(/dev/loop0). so glusterfs is out of the picture (
https://github.com/heketi/heketi/issues/665)
- cephfs is like glusterfs, so cephfs is out
- NFS requires kernel modules, so nfs is out
- HostPath doesn't work over multiple nodes

So your only option is to use KVM

I use Proxmox. I knew LXC/LXD wasn't going to be able to fulfill what I
needed to do on a single server, so I looked for a hypervisor that had a
polished UI for creating both LXC and KVM VM

I'm still going to go with glusterfs, which will also need heketi, and will
be running it in a fedora kvm. And the using it as a persistent volume for
kubernetes
