Znuny Support ticketing system

Good morning, all. I’m looking for a container for the Znuny support ticketing system (current version is v7). I have found a few out there but are the older 6.5 and don’t seem to be kept current (from what I can tell). I also don’t really have a sense of the reliability of their publisher, and this group has always been considered the reputable “gold standard” in docker images.

The hope would be for a decent production image that could support an off-image database, and work well with application updates.
