Environment Variables

Environment variables are closely related to the technology of Docker. They are usually written in the .env or .txt file right in the project directory. The main reason for using environment variables is to improve the flexibility of your application when using Docker. You can for example use a PORT environment variable to specify on which port to run a backend application (e.g., PORT=80).
