Did you consider Nix/Guix instead of docker as a suggested way to deploy? Docker is a harmful and very common tool, witch lead to a gazillion of wasted resources and security nightmare due to pulling anything from unknown sources and put it in production.
Aside, similarly, MarkDown is popular but it's really a crappy set of markups that fails in the most useful productivity aspect: outlining. Org-mode is less known being tied to Emacs but it's far, far more featuresfull and immediate to use.
Beside that's I wish the best luck to all devs, there are gazillion of webapps all suffering the modern stack issue: inability to integrate anything, so the need to recreate the wheel everytime and incorporate a feature at a time to the point of being monsters, but your sauce so far seems to be the most polished I've seen.
