How to configure an nginx.conf with a dockerised drupal website? - php

Question

this is my first time working with nginx and I'm using it to access my dockerised drupal appliction from a production subdomain.
So before everything, I'm currently using docker-compose to create my sql, app, and webservice containers, here is my docker-compose file :
version: '3'
services:
app:
image: osiolabs/drupaldevwithdocker-php:7.4
volumes:
- ./docroot:/var/www/html:cached
depends_on:
- db
restart: always
container_name: intranet
db:
image: mysql:5.5
volumes:
- ./mysql:/var/lib/mysql
restart: always
environment:
- MYSQL_ROOT_PASSWORD=linux1354web
- MYSQL_USER=root
- MYSQL_PASSWORD=linux1354web
- MYSQL_DATABASE=intranet
container_name: intranet-db
web:
build: ./web
ports:
- 88:80
depends_on:
- app
volumes:
- ./docroot:/var/www/html:cached
restart: always
container_name: webIntranet
I don't think the containers are the problem, as when I go to the drupal containers the site works, but my main problem is the link with the nginx container. Here is my nginx.conf :
# stuff for http block
client_max_body_size 1g;
# fix error: upstream sent too big header while reading response header from upstream
fastcgi_buffers 16 16k;
fastcgi_buffer_size 32k;
server {
listen 80;
listen [::]:80 default_server;
server_name _;
index index.php index.html;
error_log /var/log/nginx/error.log;
access_log /var/log/nginx/access.log;
root /var/www/html;
#RENVOYER LA PAGE DE GARDE DE APACHE2
location / {
# try to serve file directly, fallback to app.php
try_files $uri /index.php?$query_string; # For Drupal >= 7
}
location /intranet {
# try to serve file directly, fallback to app.php
try_files $uri $uri/;
}
#RENVOYER LE FICHIER ROBOTS.TXT
location = /robots.txt {
allow all;
log_not_found off;
access_log off;
}
location = /favicon.ico {
log_not_found off;
access_log off;
}
location ~ \.php(/|$) {
try_files $uri =404;
fastcgi_split_path_info ^(.+\.php)(/.+)$;
fastcgi_pass app:80;
fastcgi_index index.php;
include fastcgi_params;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
fastcgi_param DOCUMENT_ROOT $document_root;
}
}
And this is my DockerFile to build nginx image:
FROM nginx:alpine
COPY nginx.conf /etc/nginx/conf.d/default.conf
When I go to localhost:88/ I currently have a apache2 hub page, but the moment I'm trying for another page I always get a 502 bad gateway error and the logs are saying :
webIntranet | 2021/03/11 08:44:55 [error] 30#30: *1 upstream sent unsupported FastCGI protocol version: 72 while reading response header from upstream, client: 172.26.0.1, server: _, request: "GET /index HTTP/1.1", upstream: "fastcgi://172.26.0.3:80", host: "localhost:88"
To go more into details, my docker folder looks like that, docroot containes the drupal website.
I have tried sovling the problem by changing the ports as some solution mentionned it but it did nothing, I don't understand what could be wrong, I've tried many things with the conf but none of them works, and I still even can't have a single page of the drupal site showing up.

The drupaldevwithdocker-php project isn't using php-fpm, hence the response is unsupported as it's from apache rather than php-fpm. I'd imagine you'd need something more like this?
proxy_pass http://app:80;
