I’ve used lxdui a bit and it’s somewhat useful. However it’s unfinished, the UI has plenty of placeholder elements and some unlocalized strings.
I wish there were something else out there that did the business. I’ve been looking at gluing together MAAS, Juju, LXD, Snapweb and Landscape to give a all-encompassing management interface with Juju Clouds setup for backing cloud (so Storage services and hypervisor/orchestration can be deployed), LXD cluster cloud for core/app services, K8S cloud etc, Snapweb for arbitrary services to be placed wherever needed, and Landscape for centralized monitoring and updates. Still way lighter weight than Openstack, but not holistically grouped.
I still haven’t quite figured out what the real benefit of MAAS is in a testlab/devops environment - I did see in one of @stgraber’s videos that you can see containers in there, but I wonder what the extent of functionality against those is. If cluster/fan networking can be managed via MAAS, that could be very cool. Juju’s GUI is SO awesome I wish it did more, and wasn’t so clumsy.
