Welcome to the third installment of our containerization journey. Last month we covered running our application locally in Docker containers replacing our pre-existing development virtual machine. We used Laravel Sail to scaffold our development environment with Docker Compose. This month we’re going to look at a real-world application running on a traditional Linux Virtual Private Server with PHP 7.4, MySQL, Redis, and Apache. Before we can dive too far into containers, we need to get a looming task out of the way.
