I hope I will be able to release a "v1" in September, I think it will stay pretty simple, as explained on the project README (https://github.com/tsileo/microblog.pub).
For Docker, it's not a requirement, it's just that the setup is a little complex so it greatly simplifies things. I have to update the documentation on deploying, but as of right now, I would not advise to run an instance as it's still too buggy.
