Howdy,

I agree, it is.

It depends on your goals - if you are doing this just for the heck of it (and 
to learn :) then awesome.

But if you are wanting to make an "application" highly available, then 
docker/kube is the way to go. Still a learning
curve, but the environment takes care of most of the requirements and you can 
use commodity hardware.

You still need a shared storage environment, that can span multiple hosts (and 
those hosts can be virtual) - which is
where glusterfs (I found problematic, and I am not sure of its development 
status), ceph, NFS, etc can help. I would prefer gluster/ceph over NFS, since 
"NFS" is not HA and when it goes down it takes everything with it (never been a 































































































































































































































































































































































































































































































































































































































































































































































































































































































































































































fan of NFS).

Personally I use a commercial software package that provides HA storage 
(because I work for the company that makes it,
and I can put it down to skills :) With it nodes providing the storage can go 
offline, as long as there are a major of
nodes still active and atleast 1 of thoses nodes with the filesystem.

On my intel server, I use VMware to make multiple VMs and use the commercial 
software for docker, but for the Pi, I'll still use VMware to make multiple 
guests and play with gluster again.
