Well it is “working” for me. I’m using a YunoHost Lemmy 0.16.7 to type this comment :). But I agree there should be some kind of warning on the project that it’s only really partially working, and very outdated (thanks to the recent flurry in activity and changes).
Mainly though I wish YunoHost would just support Docker idiomatically and install Lemmy “as intended”. Yeah Docker can be a bit of a pain and it uses more resources, but it also has many real advantages like siloing the apps from the host system…
YunoHost “packages” are just scripts. In the case of Lemmy, Lemmy_ynh’s install script actually fetches the Lemmy Docker image and extracts the files (including pre-built binaries) from it. And then it writes the config files to use the system Psql instance instead of a containerized version.
FWIW I don’t care how YunoHost installs the apps. Whether it’s fetching and running containers, or building from source, or grabbing binaries. As long as the apps work and the reverse proxy gets wrangled it’s fine with me. Just in this case refusing to run the Docker images directly is, at least momentarily, a problem for updating the app.
