Docker
What is it?
Docker is an open-source platform that enables containerization. Containers are lightweight, isolated environments where applications run consistently regardless of the underlying system. Docker packages an application with all its dependencies in a container, solving "works on my machine" issues.
Practical example
With a Dockerfile you can containerize your Laravel app: FROM php:8.4-fpm. Then you can use docker-compose to start your whole stack (PHP, MySQL, Nginx) with a single command.
