I run nextcloud on docker (image nextcloud:production-fpm) with an nginx-container (image: nginx) as reverse-proxy (handling SSL-termination) based on the example nginx-configuation (https://raw.githubusercontent.com/nextcloud/docker/master/.examples/docker-compose/insecure/mariadb/fpm/web/nginx.conf). This works.
Now however I want nextcloud to be served in an path (i.e. mydomain.com/nextcloud instead of mydomain). I found an github-issue on this (https://github.com/nextcloud/docker/issues/401) which point at the nginx-configuration, but this only solves it for very easy configurations (adapting the nextcloud by adding - OVERWRITEWEBROOT=/nextcloud to the environment is the easiest part). Does anybody now how to adapt the nginx-configuration to serve nextcloud from a path?
I created a demo-project to illustrate my problem: compose.yml:

In this I tried to add the rewrite rule rewrite ^/localhost/nextcloud(.*) $1 break; to all relevant locations and added add_header debuglocation to all locations for debugging them with curl -v (thanks to https://stackoverflow.com/questions/12703702/nginx-test-which-location-used-to-process-request). Calling curl -v http://localhost/nextcloud/ > /dev/null returns a 404 but without debuglocation populated.
