500 (Internal Server Error) with Laravel & Docker
I found a solution. I set the permission on my Laravel app using:
sudo chmod -R 777 storage && sudo chmod -R 777 bootstrap/cache
This solution might not apply to you since you are using Nginx, but in my case I am using the php:7.0-apache as source image, so I made the Apache user the owner of my app's files.
In my Dockerfile I have:
...USER www-dataWORKDIR /var/www/htmlCOPY --chown=www-data:www-data . ....This solved the problem, so it could be worth trying, either modifying your Dockerfile or maybe Docker Compose has some option for user permissions when mounting volumes.
