My API can't read env vars

hey, im trying to deploy a php-fpm api and i got a local .env file and i got the same .env at the railway project vars, but my api doesn't seem to be able to access it My custom dockerfile:

FROM composer:2.4.4 AS composer
FROM php:7.4-fpm as base
COPY --from=composer /usr/bin/composer /usr/bin/composer
RUN mv "$PHP_INI_DIR/php.ini-production" "$PHP_INI_DIR/php.ini"

FROM base as config
COPY default.conf /etc/nginx/conf.d/default.conf

WORKDIR /var/www/html

COPY . .

RUN composer install --ignore-platform-req=ext-bcmath --no-dev

EXPOSE 8080
CMD ["/usr/bin/supervisord"]

FROM composer:2.4.4 AS composer

WORKDIR /var/www/html

COPY . .

RUN composer install --ignore-platform-req=ext-bcmath --no-dev

EXPOSE 8080
CMD ["/usr/bin/supervisord"]

Im reading the vars in code using

$_ENV['AWS_S3_ENV']

$_ENV['AWS_S3_ENV']

What am i doing wrong?

Solution:

nvm. using $_SERVER worked

Brody•2y ago

oh so you arent actually using these variables during build, only after the app has started

MedimOP•2y ago

yeye

Brody•2y ago

then you dont need them in the dockerfile at all

MedimOP•2y ago

Brody•2y ago

show me your service variables

MedimOP•2y ago

Brody•2y ago

show me how your code is accessing the variables

MedimOP•2y ago

Brody•2y ago

whats this $_ENV thingy

MedimOP•2y ago

to access the env var

Brody•2y ago

doesnt php use getenv

MedimOP•2y ago

just if u wanna mutate it i guess

MedimOP•2y ago

nvm

Brody•2y ago

try it?

MedimOP•2y ago

but theres also AUGH

Brody•2y ago

also try echoing all the environment vars you know, super basic debugging stuff 🙂

MedimOP•2y ago

...not possible lmfao

Brody•2y ago

it has to be

MedimOP•2y ago

yeah, blame slim-php/php-fpm/composer cant log shit there

Brody•2y ago

log it somewhere else

MedimOP•2y ago

trust me, i can't gotta be trial and error

Brody•2y ago

bruh slap a single index.php file in an /app folder and print the environment variables

MedimOP•2y ago

yeah, thats a good option

Brody•2y ago

not possible my ass

MedimOP•2y ago

Brody•2y ago

Solution

Medim•2y ago

https://test-service2.up.railway.app/

MedimOP•2y ago

now u ask me why? idk

Brody•2y ago

<?php print_r($_ENV); ?>

<?php print_r($_ENV); ?>

MedimOP•2y ago

hmm I'm wondering why $_SERVER instead of $_ENV

Brody•2y ago

youve mucked something up somewhere

MedimOP•2y ago

yeah I needed a custom package to read env vars cause php-fpm can't do it by itself it seems https://github.com/vlucas/phpdotenv

Brody•2y ago

kinda cringe php

MedimOP•2y ago

it worked flawlessly thanks @Brody

Brody•2y ago
