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

WORKDIR /var/www/html

COPY . .

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

EXPOSE 8080

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

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

Medim•14mo ago

yeye

Brody•14mo ago

then you dont need them in the dockerfile at all

Medim•14mo ago

Brody•14mo ago

show me your service variables

Medim•14mo ago

Brody•14mo ago

show me how your code is accessing the variables

Medim•14mo ago

Brody•14mo ago

whats this $_ENV thingy

Medim•14mo ago

to access the env var

Brody•14mo ago

doesnt php use getenv

Medim•14mo ago

just if u wanna mutate it i guess

Medim•14mo ago

nvm

Brody•14mo ago

try it?

Medim•14mo ago

but theres also AUGH

Brody•14mo ago

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

Medim•14mo ago

...not possible lmfao

Brody•14mo ago

it has to be

Medim•14mo ago

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

Brody•14mo ago

log it somewhere else

Medim•14mo ago

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

Brody•14mo ago

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

Medim•14mo ago

yeah, thats a good option

Brody•14mo ago

not possible my ass

Medim•14mo ago

Brody•14mo ago

prints to browser window, it dont matter obviously dont use the real credentials for this type of testing

Medim•14mo ago

Solution

Medim•14mo ago

Brody•14mo ago

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

Medim•14mo ago

now u ask me why? idk

Brody•14mo ago

<?php print_r($_ENV); ?>

<?php print_r($_ENV); ?>

Medim•14mo ago

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

Brody•14mo ago

youve mucked something up somewhere

Medim•14mo 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•14mo ago

kinda cringe php

Medim•14mo ago

Brody•14mo ago
