How to manage and pass env values into WordPress through Coolify

Steps

1. Go to your project
2. Open your environment (e.g. production)
3. Click your WordPress service
4. On the left sidebar → click Environment Variables
5. Switch to Developer view (important)
6. Add your keys and then the WORDPRESS_CONFIG_EXTRA so it should look like this:

KEY_1=XXX
KEY_2=XXX
WORDPRESS_CONFIG_EXTRA=define('KEY_1', getenv('KEY_1')); define('KEY_2', getenv('KEY_2'));

Then save the environement variables and deploy (or restart).

Notes (so you don’t get caught again)

• Use Developer view, not Normal view
• Keep everything single-line (i.e. don’t select Is Multiline?)
• Don’t select Is Literal?
• Don’t wrap anything in quotes
• WORDPRESS_CONFIG_EXTRA injects directly into wp-config.php
