.env not generating

[MattEzekiel]

I'm having trouble deploying my Laravel app. Honestly, I'm new to this and don't know much about infrastructure, Docker, etc.
So, I've been following various tutorials and reading on Google, but I can't find a way to complete the deployment.
My project is a Laravel 12 project. I configured the variables from the project/application.
The build works fine, but I get warnings in the logs like: Your app configuration references the DB_URL environment variable, but it is not set.

But if I go through the terminal and printenv, I see the environment variables, but not the .env that the app thinks it wants to look for.
I didn't do any additional configuration. I don't know if dokploy automatically understood the project or what happened, but it detects that it's a Laravel project and handles the entire build correctly, except for the .env files. What do I need to do to configure this correctly?
