   Hi!
   Where did you see something about /usr/src?

   It's /var/www/html (

   docker/fpm/Dockerfile

   Line 106 in d1f327e

   tar -xf phpMyAdmin.tar.xz -C /var/www/html --strip-components=1; \

   ) ,can you share your docker compose file?

   I am currently thinking that there is no need to volume mount, and after that maybe it could be a local path issue sending the request to fpm

   This works well. The real problem are the resource files (CSS, JS), I usually use a volume to make them accessible through the host file system like this:

   Okay I get it, it works but no files are recognized by apache2 as tbey do not exist on the host file system

   Hmm, maybe run the apache2 version and proxy the http traffic to it?

   This relates to #362

   All this was caused by #285

   /usr/src/phpmyadmin was mentioned here: #253 (comment)

   Stackoverflow post is here: https://stackoverflow.com/questions/75268068/problem-with-static-files-using-phpmyadminfpm-alpine-behind-apache2

   Issue #362 seems to be the same issue. I use plain docker, so I don't have a docker compose file and Apache2 doesn't run within docker, but directly on the host system.

   My understanding at this point is, Dockerfile-alpine.template extracts directly to /var/www/html and if this is part of a mounted volume (-v), the extraction doesn't work and /var/www/html is empty.

   I think the steps to reproduce the problem are simple, start the container with a mount to /var/www/html:

   docker run -e PMA_HOST=host.docker.internal --name phpmyadmin --add-host host.docker.internal:host-gateway -v /var/www/phpmyadmin:/var/www/html -p 9000:9000 -d phpmyadmin:fpm-alpine
   

   And then check the /var/www/html directory on the container, it's empty:

   docker exec -it phpmyadmin /bin/sh
   /var/www/html # ls -al
   total 0
   drwxr-xr-x    2 root     root             6 Jan 31 20:28 .
   drwxr-xr-x    1 root     root            18 Nov 12 08:36 ..
   /var/www/html #
   

   Run the container without mount (-v) and all the files are there:

   docker exec -it phpmyadmin /bin/sh
   /var/www/html # ls -al
   total 672

   e.g., I also use postfixadmin which is small but similar in the structure:

   The Dockerfile seems to extract everything to /usr/src/postfixadmin
   https://github.com/postfixadmin/docker/blob/master/fpm-alpine/Dockerfile

   Where the docker-entrypoint.sh then copies everything to /var/www/html
   https://github.com/postfixadmin/docker/blob/master/fpm-alpine/docker-entrypoint.sh

   This is what docker logs shows in case of postfixadmin:

   Postfixadmin not found in /var/www/html - copying now...
   WARNING: /var/www/html is not empty - press Ctrl+C now if this is an error!
   ...
   Complete! Postfixadmin has been successfully copied to /var/www/html
   

   I need access to the resource files, since fpm couldn't serve these files directly, this would result in following errors for any non php files:
