I spent a few days trying to get a lemmy instance going through docker before throwing in the towel and just using the ansible method. This limits the amount of customizability, but the docker documentation is currently completely wrong. There are a few PRs open to fix this, but only the repo owners can approve, so we're basically waiting on that.

I tried the "From Scratch" method and failed miserably.
Nowadays everything is "step 1: install docker" which is a valid tool, but it's not the all-around solution for everything.
Indeed. Also my failure comes from the rather unwelcome way of lemmy failing: "Error!" message on the UI without any error in any log, indicating any problems. I ws thinking about trying to debug it but needs lots of hours just to figure out how they imagined debugging...
The documentation was put together by people that have a detailed knowledge of things and have lots of technical experiencr. I have a feeling that if some things are missing, it's probably because they assume that someone setting this up already had a certain level of experience and therefore would already know what to do. More than likely they didn't feel that every tiny step was needed as there would be a certain amount of common knowledge already.
