Trouble configuring Laravel with nginx and docker-compose

Question

I'm having trouble to config my Laravel application to run on my web server.

The problem is that I'm getting the Welcome to nginx! page and not my laravel app when using the browser.

The set up is the following

It's a server running on Ubuntu 20.04 LTS
The nginx service is installed directly on the machine (not using docker)
I have a docker-compose to run 3 containers: postgres (database) + keycloak (auth server) + My laravel app.

Keycloak and the postgres db are running like charms for months.

Laravel app path -> /var/www/dev.mycompany.com/

Laravel Dockerfile -> /var/www/dev.mycompany.com/Dockerfile

FROM php:8.0-fpm

# Copy composer.lock and composer.json
COPY composer.lock composer.json /var/www.dev.mycompany.com

# Set working directory

# Add user for laravel application

# Copy existing application directory contents

# Copy existing application directory permissions

# Change current user to www
USER www

# Expose port 9000 and start php-fpm server
EXPOSE 9000
CMD ["php-fpm"]

Nginx - Laravel Config path: /etc/nginx/sites-available/www/dev.mycompany.com HTTP is not configured yet, I was just testing with 443 before writing a rule to redirect all none https requests

server {
    listen 443;

        #fastcgi_pass dev.mycompany.com:9000;
        fastcgi_pass unix:/var/run/php/php8.0-fpm.sock;
        fastcgi_index index.php;
        include fastcgi_params;
        fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;

    }
    location / {

Thanks A LOT by advance

Why is this: #fastcgi_pass dev.mycompany.be:9000; commented out? The Dockerfile runs php-fpm and exposes port 9000. Since all containers are running on the same machine, the php container should be accessible via localhost with fastcgi_pass localhost:9000 — guyg

You're right, I've changed my nginx config like this, but nothing changes. Still getting Nginx Welcome page. fastcgi_pass localhost:9000; #fastcgi_pass unix:/var/run/php/php8.0-fpm.sock; — NotGael

And a correction was made to the Dockefile COPY composer.lock composer.json /var/www/dev.mycompany.com WORKDIR /var/www/dev.mycompany.com Changes /var/www.dev.mycompany.com to /var/www/dev.mycompany.com But still ... nothing changes Entering into the container I've checked that the app files are in /var/www/dev.mycompany.com and that the Laravel app is working properly. The app has been builded and the key generated, ... php artisan is working just fine .... — NotGael

After you made the configuration changes, did you reload nginx? — guyg
– guyg, Commented Dec 3, 2021 at 10:13
Yes I did that. But finally got it working by starting all over. — NotGael

Got it working by starting all over to zero and finishing with this config

The reason it was not working before maybe because the server_name was missing in the nginx config and the Dockerfile had error in the script to correctly work with php 8 ???
