feat: Ability to create root user via environment variables

[peaklabs-dev]

Changes

• feat: Ability to set the initial root user (instance admin user) of Coolify in the .env file via environment variables:

  • ROOT_USERNAME=
  • ROOT_USER_EMAIL=
  • ROOT_USER_PASSWORD=

• feat: Registration is automatically disabled if you set up a root user via the .env file

• feat: Logic, error handling and clean log output for each scenario:

  • Environment variables do not pass validation rules
  
  • Root user created successfully
  
  • Root user already exists, skipping creation
  

• Security fix: After initial installation, the Registration page is exposed with the registration form. This is usually not an issue as one installs and registers within seconds/minutes after the URL becomes publicly accessible. However, if you leave the registration page too long without registering a user, a malicious actor can potentially register and compromise your system.

-> The new way of setting your root user in the .env file can prevent the registration page from ever being accessible to the internet.

Note

• At the moment, the registration page is only inaccessible (all the time) if you use manual installation because the automated script downloads the .env file during installation, and then the user has to fill in the values in the .env file after Coolify is already installed and then run the script again (registration page will be live for a few seconds like this). In the future, we can make the script more interactive and ask for a username, email, and password.
• For security purposes, the env values only take effect if the root user does not yet exist, so you cannot override the existing root user with these env values.
