Load environment variables from dotenv with v7 and Symfony 6

[ToshY]

It was suggested to use deployer/dist in #2860, but that leaves me with the problem that I don't know how to load enviroment variables from my .env file properly anymore.

Previously in Symfony 5, using deployer/deployer:v7.0.0-rc.3, a possible solution was provided here, which was suggesting using symfony/dotenv to load the environment variables.

<?php

namespace Deployer;

use Symfony\Component\Dotenv\Dotenv;

require 'recipe/common.php';
require 'contrib/discord.php';

$dotenv = new Dotenv();
$dotenv->loadEnv(__DIR__ . '/.env');

set('application', $_ENV['APP_NAME']);
set('discord_channel', $_ENV['DISCORD_DEPLOY_CHANNEL']);
set('discord_token', $_ENV['DISCORD_DEPLOY_TOKEN']);
...

This worked, and while I'm not sure if it was the best solution for the problem at hand, it got the job done.

Now I've tried the suggestion using deployer/dist:v7.0.0-rc.3 (with Symfony 6), and without knowing/realizing about the possible differences between deployer/deployer and deployer/dist, I just tried to see if it worked, resulting in the following error message when trying to display help:

Class "Symfony\Component\Dotenv\Dotenv" not found

So now I'm just stuck on what to do next. What is a proper way to load (all) environment variables so I can use them throughout my deploy.php?

Include your autoload.php or use https://deployer.org/docs/7.x/recipe/common#dotenv

@antonmedv Tried adding require_once 'vendor/autoload.php'; to my deploy.php which didn't make any difference.

And the link you're referrencing states the following in the docs:

Path to .env file which will be used as environment variables for each command per run().

Which is not the point of what I'm trying to achieve here, because I want to be able to use the environment variables throughout the deploy script, so I can simply set the application name from the variable available in the .env file.

Could you please elaborate on it further or maybe supply a sample of a working deploy script for Symfony 6 using deployer/dist:v7.0.0-rc.3?

[antonmedv]

Maybe include it right into Deployer?

[ToshY]

Sorry but could you be a bit more specific on how to do this exactly?

For the ones looking for an answer, you will need to manually require the autoloader using require_once __DIR__ . '/vendor/autoload.php';
