Instead of using a static username/password and HTTP Basic
authentication for the Longhorn UI, we can now use Authelia via the
*nginx* auth subrequest functionality.
I was originally going to use GlusterFS to provide persistent storage
for pods, but [Heketi][0], the component that provides the API for
the Kubernetes StorageClass, is in "deep maintenance" status and looks
to be practically dead. I was a bit afraid to try to use it because of
that, and went looking for guidance on Reddit, which is how I discovered
Longhorn.
