Deployment Issue: Nginx Container Not Responding (503 Error)

After successfully deploying my Laravel application with Dockerfile to Railway, I am encountering a 503 error when trying to access the application using the provided URL below. Deployment Details: Project Id: 5eff00b6-887c-4fb9-9f2f-02c7fb94d78c Deployment URL: https://innoscripta-assessment-backend-production.up.railway.app/ Steps Taken So Far: 1 - Checked Nginx Configuration: I reviewed the Nginx configuration file and ensured that it is properly set up to route traffic to the Laravel PHP-FPM container. 2 - Verified Environment Variables: I have confirmed that all the required environment variables, such as DB_CONNECTION, DB_HOST, DB_PORT, DB_DATABASE, DB_USERNAME, DB_PASSWORD, and others, are correctly set in the railway environment. 3 - Restarted the Containers: I tried restarting all the containers, but the issue persists. 4 - Verified Port Mapping: I have confirmed that the Nginx container is correctly mapped to port 80 on the host machine, and the Laravel PHP-FPM container is mapped to port 9000. 5 - Reviewed Application Logs: The logs for the app-1 container do not show any errors. It only displays the following message: "[03-Aug-2023 23:47:00] NOTICE: fpm is running, pid 1 [03-Aug-2023 23:47:00] NOTICE: ready to handle connections." and I do not see any error logs related to Nginx in the railway dashboard logs (I only see the app container logs). Request for Assistance: I kindly request your support in identifying and resolving the root cause of the issue. Please investigate the Nginx container's logs and any other relevant logs that may help pinpoint the problem. Any insights or guidance to resolve this matter would be greatly appreciated. Please let me know if you require any further information to assist in resolving this issue.

have nginx listen on a non privileged port like 8080, and then in your railway service variables set a PORT variable to 8080 as well

coldgrooveOP•16mo ago

Changed the nginx.conf file and added a PORT variable set to 8080 as well and redeployed. No luck 😦 here is my file:

server {
    listen 8080;
    server_name localhost;
    root /var/www/html/public;

    index index.php index.html index.htm;

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

    location ~ \.php$ {
        fastcgi_pass app:9000;
        fastcgi_index index.php;
        fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
        include fastcgi_params;
    }

    location ~ /\.ht {
        deny all;
    }
}

server {
    listen 8080;
    server_name localhost;
    root /var/www/html/public;

    index index.php index.html index.htm;

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

    location ~ \.php$ {
        fastcgi_pass app:9000;
        fastcgi_index index.php;
        fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
        include fastcgi_params;
    }

    location ~ /\.ht {
        deny all;
    }
}

Brody•16mo ago

show me your service variables please also, have you tried deploying your app with nixpacks instead of a dockerfile?

coldgrooveOP•16mo ago

No, I don't know much about deploying with nixpacks. Do you need the values of the env vars or you want to check the keys only?

Brody•16mo ago

I just wanted a screenshot, now you've shown me all your keys, please go and regen them

coldgrooveOP•16mo ago

np i changed the values keeping the general structure

Brody•16mo ago

send your dockerfile please

Brody•16mo ago

does php:8.1-fpm include nginx?

coldgrooveOP•16mo ago

i don't think so

root•16mo ago

Try adding nginx to the apt-get install command then?

Brody•16mo ago

I think you should try deploying with nixpacks

root•16mo ago

^ this I have spent rather an amount of time getting the Nixpacks PHP provider to Just Work™️, so hopefully it should.

Brody•16mo ago

spoiler alert, it's still sub par what this involves is removing your dockerfile and nginx.conf

root•16mo ago

You can also just rename them to .bak or something if you want, to keep them around

Brody•16mo ago

^ this

coldgrooveOP•16mo ago

Oh man, i really don't know anything about nixpacks and I don't have time for it (this project was for an assessment and I'm at the end of the deadline)

root•16mo ago

You can just delete those two files and it should Just Work™️ That's the point of nixpacks

Brody•16mo ago

took the words right out of my fingers

coldgrooveOP•16mo ago

Oh yeah so no configuration files like Dockerfile whatsoever?

Brody•16mo ago

that's the point

root•16mo ago

zigacktly

coldgrooveOP•16mo ago

aight lemme try it

Brody•16mo ago

nixpacks probably won't pick up on the libpg libjpeg etc stuff though

root•16mo ago

it might I'm not sure

Brody•16mo ago

depends on how well you did with the php provider

root•16mo ago

It'll install the required extensions, which should hopefully have such things as dependencies

Brody•16mo ago

hopefully ™️

root•16mo ago

™️©️ ®️

Brody•16mo ago

😬

coldgrooveOP•16mo ago

returned 403 😄

root•16mo ago

nooooooo

Brody•16mo ago

hey that's better than 503!!

root•16mo ago

oh wait what does the page say Understand here, none of us are PHP developers

coldgrooveOP•16mo ago

me neither brotha first time trying it I have this in the deploy logs tho: "Looks like your app is listening on 127.0.0.1. You may need to listen on 0.0.0.0 instead."

root•16mo ago

I wrote the provider, but I'd still rate myself as a beginner hrrrm could you send the logs?

coldgrooveOP•16mo ago

message.txt

root•16mo ago

well that's weird

coldgrooveOP•16mo ago

root•16mo ago

I don't know where that message popup is coming from, you can ignore it oh I see where it's coming from. you can still ignore it though hmm do you have a public directory?

coldgrooveOP•16mo ago

oh shii, do i need to remove the .dockerignore too?

root•16mo ago

no, it's using nixpacks do you have a public directory in your app though?

coldgrooveOP•16mo ago

I ve a public directory in the root

root•16mo ago

all this is nixpacks doing black magic with Perl regexes to tell you that your app might have problems

root•16mo ago

oh, I think I might know what's happening What are the permissions on the public directory? wait nvm I'm tired, disregard that question

coldgrooveOP•16mo ago

I have .htaccess file inside the public directory if you mean that

root•16mo ago

.htaccess won't actually do anything here, since this is Nginx Try adding a nixpacks.toml to your project:

[start]
cmd = "chmod ugo+rwx /app/public && perl /assets/prestart.pl /assets/nginx.template.conf /nginx.conf && (php-fpm -y {} & nginx -c /nginx.conf)"

[start]
cmd = "chmod ugo+rwx /app/public && perl /assets/prestart.pl /assets/nginx.template.conf /nginx.conf && (php-fpm -y {} & nginx -c /nginx.conf)"

Brody•16mo ago

see this is what I mean by subpar, you shouldn't need to be chmod'ing anything

root•16mo ago

s/subpar/secure Nginx runs as a different user so people can't hack your server

Brody•16mo ago

doesn't the chmod in your nixpacks.toml undo anything that was secure

root•16mo ago

shhh

coldgrooveOP•16mo ago

nope, didnt work

coldgrooveOP•16mo ago

couldnt even open it?

root•16mo ago

oh oops

[start]
cmd = "chmod ugo+rwx /app/public && perl /assets/prestart.pl /assets/nginx.template.conf /nginx.conf && (php-fpm -y /assets/php-fpm.conf & nginx -c /nginx.conf)"

[start]
cmd = "chmod ugo+rwx /app/public && perl /assets/prestart.pl /assets/nginx.template.conf /nginx.conf && (php-fpm -y /assets/php-fpm.conf & nginx -c /nginx.conf)"

coldgrooveOP•16mo ago

I'd renamed the dockerfiles to .bak but i think it was still picking up those for some reason removing those entirely worked tho

root•16mo ago

huh that is very odd anyway, glad it works!

coldgrooveOP•16mo ago

classic home page returns i'll test the api routes now but thank you guys for the assistance!

root•16mo ago

It was definitely using nixpacks though, so I'm confused no problem!
