How can I modify the nginx configuration in Railway?

I'm getting a "413 Request Entity Too Large" when uploading images to my Laravel app deployed with Railway (which is using Nixpacks). I think that this can be solved by modifying the "client_max_body_size 20M;" in in /etc/nginx/nginx.conf. However, I can't figure out how can I access this configuration file Railway. How can I make such a configuration in Railway?

Create a nginx.template.config file in the root of your application. Add the content as follows:

worker_processes 5;
daemon off;

worker_rlimit_nofile 8192;

events {
  worker_connections  4096;  # Default: 1024
}

http {
    include    $!{nginx}/conf/mime.types;
    index    index.html index.htm index.php;

    default_type application/octet-stream;
    log_format   main '$remote_addr - $remote_user [$time_local]  $status '
        '"$request" $body_bytes_sent "$http_referer" '
        '"$http_user_agent" "$http_x_forwarded_for"';
    access_log /dev/stdout;
    error_log /dev/stdout;
    sendfile     on;
    tcp_nopush   on;
    server_names_hash_bucket_size 128; # this seems to be required for some vhosts


    client_max_body_size 20M;  # Modify this to fit you needs

    server {
        listen ${PORT};
        listen [::]:${PORT};
        server_name localhost;

        $if(NIXPACKS_PHP_ROOT_DIR) (
            root ${NIXPACKS_PHP_ROOT_DIR};
        ) else (
            root /app;
        )

Thanks a lot for the support. This is a point in the right direction, but it's still not uploading the file. I figured out myself that the correct file name is nginx.template.conf and not .config, but now I have this error: "POST Content-Length of 9218627 bytes exceeds the limit of 8388608 bytes". I guess this should be modified in the php.ini file but, again, I can't see where I can modify that in Railway. Finally I could change the php.ini configurations adding this code to the web.php file: Route::group(['middleware'=>'custom_middleware'], function () { ini_set('upload_max_filesize', '5000M'); ini_set('post_max_size', '5000M'); }); Nevertheless, it's still not working as now it's showing the following error: " The "" file does not exist or is not readable."

nilsuria•2y ago

I see that this could be related to the permissions of the temporary path that nginx is using to store large images as pointed here: https://github.com/laravel/framework/issues/31249

But I cant see how to modify the permissions on this path (/var/lib/nginx/tmp/client_body) as pointed in the answers to the post

Apologies for giving the wrong file name. It is unfortunate that modifying the nginx.template.conf did not work for you. All the best.

nilsuria•2y ago

It worked! But it's still something missing there. I guess now the problem is related to the permissions of the temporary path that nginx uses to store the images.

Are you running Laravel 6?

nilsuria•2y ago

No, I'm runing Laravel 9 9.52.7 to be exact

After many changes, I see that the code I added to change the value of 'upload_max_filesize' is not really changing the value in php.ini. How I can modify this value in Railway?

Try deploying your app using docker instead of Nixpacks.

nilsuria•2y ago

I've been trying to do so, but I can't get the correct Dockerfile configuration. The template provided by Railway is missing the Dockerfile: https://github.com/railwayapp-templates/laravel
