Nginx, PHP-FPM, MySQL and Symfony using Docker : Nginx 502 Bad Gateway and Symfony No route found exception -

this post quite long, make sure have drink near you.

basically, want use docker make nginx container, php-fpm container, mysql container , symfony container contain code of symfony app.

i've been trying make things work whole week, been reading things, unfortunately nothing worked.

i made docker-compose.yml, uses dockerfiles nginx, php-fpm , symfony. mysql based on image hosted on dockerhub.

i installed , finally, after week of work still encounter 2 types of error :

nginx gives me "502 bad getaway" randomly. it's because of port error if nginx fastcgi_pass parameter wasn't set @ right value, is, don't quite understand problem.

then, symfony gives me "no route found /" don't understand why, since website works on production , colleagues. suspicious database since when it's empty give me error. took dump database didn't give concluent.

here files want
