title: Sharing a folder between Docker-Containers with precompiled files
body: <p>I use Github Actions to make a php-fpm Docker Container with Laravel and precompiled Docker Compose Files in it. The CSS and JS files are made with npm. This Docker Container is than pushed to my Docker Regestry.</p>
  <p>I want to check this Container out and let it rund with Docker-Compose and a nginx container runs with this Configuration:</p>
  <pre><code>server {
      listen 80;
      index index.php index.html;
      error_log  /var/log/nginx/error.log;
      access_log /var/log/nginx/access.log;
      root /var/www/public;
      location ~ \.php$ {
          try_files $uri =404;
          fastcgi_split_path_info ^(.+\.php)(/.+)$;
          fastcgi_pass app:9000;
          fastcgi_index index.php;
          include fastcgi_params;
          fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
          fastcgi_param PATH_INFO $fastcgi_path_info;
      }
      location / {
          try_files $uri $uri/ /index.php?$query_string;
          gzip_static on;
      }
  }
  </code></pre>
  <p>So the PHP Part runs perfectly, but the CSS and JS part is not working, because the app Container has this files. How can i copy, share or something else between this two Containers?</p>
  <p>You cant put in a Volume from the host, because the Volume will only contain, whats on the Host, and not whats in the Container ... it has to be to the other Direction.</p>
