I have a similar problem to NextCloud FPM Docker Image behind an NGinX Docker Container as Proxy Reverse
I have multiple web apps running in Docker containers behing a Nginx reverse-proxy.
I'm trying to install Nextcloud 25 with the standard image (actually, I want to upgrade from owncloud to nextcloud but I want to have a running instance of Nextcloud first ; that's why I'm starting with nextcloud:25-fpm
image).
Since I have several web apps served by nginx, I mount the files for each app in the nginx container in a subdir of /var/www/html
; Nextcloud files are in /var/www/html/nextcloud
Summary of where I am
- containers are running
- I can access
index.php
in a browser (so nginx does proxy the requests to the fpm container) - the static files are not served (
index.php
is served instead) - I have not yet gone through the installation process of Nextcloud
docker-compose.yml (edited relevant snippet)

This settings allow a request to go though the proxy to the fpm container, as this log entry from the nextcloud container shows :
nextcloud_1 | 172.29.0.8 - 04/Dec/2023:17:30:37 +0100 "GET /index.php" 200
Indeed, I can access index.php from a browser, but the static files are not served.
The nginx log shows
nginx_1 | 176.145.75.3 - - [04/Dec/2023:17:30:36 +0100] "GET /core/css/server.css?v=ba222ded25d957b900c03bef914333cd HTTP/2.0" 200 2510 "https://cloud.example.com/index.php" "Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/53
7.36 (KHTML, like Gecko) Chrome/119.0.0.0 Safari/537.36" "-"(/var/www/html/owncloud/index.php -> GET /core/css/server.css?
v=ba222ded25d957b900c03bef914333cd HTTP/2.0)[ pathinfo : /core/css/server.css / uri : /index.php/core/css/server.css ]
It seems the url for the static files are proxied as index.php/core/css/server.css
.
For nginx, the static files are in /var/www/html/owncloud
(document_root
),
but for php-fpm, they are in /var/www/html
(while document_root
is still /var/www/html/owncloud
) ;
I suppose this is a problem since index.php
is supposed to process them.
I'm quite puzzled…
Should I first go through the installation process (so index.php
knows where to look for the static files) ?
Best Answer
These directives in the config should do the trick
So in your case /etc/nginx/conf.d/nextcloud.conf
