Hey Mdriod,

Usually there is a main nginx.conf file or a specific virtual host file and then you can modify that file with your redirection rules. This is a sample file, your mileage may vary.

server {
    listen 80;
    server_name yourdomain.com www.yourdomain.com;

    # Redirect all HTTP traffic to HTTPS
    return 301 https://$server_name$request_uri;
}

server {
    listen 443 ssl;
    server_name yourdomain.com www.yourdomain.com;

    # SSL configuration

    # Root directory and index file
    root /var/www/yourproject;
    index index.php index.html;

    # Redirect specific paths
    location /old-path {
        return 301 /new-path;
    }

    location /another-old-path {
        return 301 /another-new-path;
    }

    # PHP-FPM configuration
    location ~ \.php$ {
        include snippets/fastcgi-php.conf;
        fastcgi_pass unix:/var/run/php/php7.4-fpm.sock;  # Adjust PHP version
    }

    location / {
        try_files $uri $uri/ /index.php?$query_string;
    }
}

mmm isn't it with the nginx.template.conf file in the root directory?

template isn't used by NGINX, it's there as a base line, you will need to duplicate and rename it.

Ahh I understand, so the nginx.conf file, do I have to generate it somewhere or is it already generated to set it up?

Angelo is slightly mistaken here, you do indeed wan't to have a nginx.template.conf file in the root directory if that is the route you want to go.

This is the default file in use by nixpacks -

https://github.com/railwayapp/nixpacks/blob/main/src/providers/php/nginx.template.conf

You can download that, place it in the root directory and modify it to your needs and it will be used instead of the default.

It's ran through a pre-run script that does variable expansion during runtime before it's passed to nginx.

Or, without having to modify a config file, you can try setting NIXPACKS_PHP_FALLBACK_PATH to /index.php

Nixpacks php docs -

I did as he told me, downloaded the nginx.template.conf and renamed it nginx.conf and put it at the root of my project. Now he's breaking my container with this mistake:

nginx: [emerg] directive "include" is not terminated by ";" in /app/nginx.conf:11

But it's supposed to put the semicolon and aside it's a copy and paste.

Sorry for not being clear, but you do not want to rename that file, the filename should stay as nginx.template.conf

Without needing any config files, have you tried my other proposed solution of setting the NIXPACKS_PHP_FALLBACK_PATH variable?

XAMPP uses Apache and not Nginx, so you need to use an .htaccess file to redirect traffic. You should implement an image that uses the same development server, in this case, Apache, as Nginx handles traffic differently. Here is an example of an .htaccess file that redirects all traffic:
.htaccess save in to root app
RewriteEngine On

RewriteCond %{REQUEST_FILENAME} !-f

RewriteCond %{REQUEST_FILENAME} !-d

RewriteRule ^(.*)$ index.php [QSA,L]

example dockerfile for apache same for xampp

FROM php:8.1-apache

# Copy your code to the web server root directory

COPY . /var/www/html/

# Enable necessary modules

RUN a2enmod rewrite

# Set the environment

ENV APACHE_DOCUMENT_ROOT /var/www/html

# Expose port 80

EXPOSE 80

# Start Apache in the foreground

CMD ["apache2-foreground"]

I think it would be a little drastic to move to apache at this point.

Sorry for not being clear, but you do not want to rename that file, the filename should stay as nginx.template.conf

Thank you all for the help I have already managed to make the redirect correctly. The solution was as @Brody said, not to change the file's name to nginx.conf and with that it worked.

Without needing any config files, have you tried my other proposed solution of setting the NIXPACKS_PHP_FALLBACK_PATH variable?

No, it's not a thing. I haven't used that because it wasn't used and in documentation it doesn't give many examples to understand them either. I also wanted to change the PHP version but I didn't quite understand it.

I assure you it is a thing, the docs for the php provider does explain the variable and gives a usecase and example, please see docs page -https://nixpacks.com/docs/providers/php

But if you got it working how you want with a config then that's just as good!

I also wanted to change the PHP version but I didn't quite understand it.

The version of php that is used is based on what you have set in your composer.json file.
