Developing software across teams can be challenging due to varying operating system preferences and deployment environments. Docker solves this problem by creating isolated, lightweight execution environments called containers, which share the underlying operating system kernel but run independently. In this article, we'll learn how to use Docker with a Symfony project, including setting up the database, PHP container, Nginx web server, and creating a quote application that uses Doctrine ORM and Twig template engine. We'll also create a QuoteController to retrieve quotes from the database and display them in a view using Bootstrap styling.
