Dokku has a very easy solution for connecting databases and other services to an app with "Dokku link." Currently with Coolify I have to spin up a database then take the link generated, like postgres://user:pass@host/link and then paste it into my env file for my app. It would be cool for Coolify to automatically inject those environment variables into my app when I link two services and apps together like Dokku does. It just needs to tell me what env variable I should be looking for, like DATABASE_URL, and then I can use that variable in my app.
