marioja/rainloop repository overview

See this branch https://github.com/marioja/Mailu/tree/test-startup⁠ for webmail/rainloop/Dockerfile that created this image. Also see this comment for the description of an issue I am investigating: https://github.com/Mailu/Mailu/pull/2187#discussion_r796225044⁠

I am trying to find out why some configuration changes in /etc/nginx/http.d/rainloop.conf do not work when the docker-compose up -d command is used but does work when I docker-compose restart the container that contains the rainloop.conf nginx config file.
