I'm using Craft 3 and I have 2 Sites setup.

In my config/general.php file I have:

return [
    '*' => [
        'environmentVariables' => [
            'baseAssetsUrl' => '//'.strtolower($_SERVER['SERVER_NAME']).'/assets/',
            'baseAssetsPath' => realpath(dirname(__FILE__)).'/../web/assets',

    'craft3uk.dev' => [
        'timezone' => 'Europe/London',
        'siteUrl' => 'http://www.craft3uk.dev/',

    'craft3me.dev' => [
        'timezone' => 'Asia/Dubai',
        'siteUrl' => 'http://www.craft3me.dev/',

    'dev' => [
        'devMode' => true,

    'staging' => [

    'production' => [

I can access the variables fine in a template like:

{% set baseAssetsUrl = craft.app.config.general.environmentVariables.baseAssetsUrl %}
{% set baseUploadsUrl = craft.app.config.general.environmentVariables.baseUploadsUrl %}

But when I try using {baseAssetsPath} like this

I get:

I'm a bit confused as I have a Craft 2 site setup the exact same way and this works fine.

I cannot see anything in the Craft 3 docs regarding this either?

Can anyone help me out please?


Environmental variables as such don't exist "as a thing" in Craft 3. Instead, you'd define your Volumes in the AdminCP and override anything you need in craft/config/volumes.php

You can see an example of how to do it here: Craft 3 Multi-Environment
