Include OpenResty in the base Docker image. This is so we can run OpenResty in front of Danbooru as a reverse proxy to serve static assets (CSS, JS, and static images living in public/images). Including the proxy in the same container as the static assets avoids a lot of problems with trying to share files across separate containers.
Config
This directory contains configuration files for Danbooru.
To configure your Danbooru instance, copy danbooru_default_config.rb to danbooru_local_config.rb and edit it. See danbooru_default_config.rb for details.
The only file here that end users need to be concerned about is danbooru_default_config.rb. The rest of the files here are internal Rails-related configuration files that end users shouldn't need to edit.
