Since the Hubzilla Start shutdown is imminent, I deployed a new Hubzilla instance and cloned my channel to it. The magic of Zot made this process pretty seamless. What was not seamless was updating my Docker Compose system to use Debian Buster and Traefik v2 and refactoring the configuration using a single environment variable file.
I've been out of the loop for a while, so if there is an "official" Hubzilla Docker image I can try contributing to that as well. hubzilla-docker
