Core Concept 1: The "Locked Box" (Why We Must Use Docker)
27 October 2025
Stop fighting "it broke on Monday" and "it works on my machine" bugs!
The "Locked Box" isn't just a container—it's your guarantee of pipeline sanity. Your Dockerfile creates an immutable environment that locks in PHP 8.3, all your extensions, and essential tools like acli for perfect, portable execution today, tomorrow, and a year from now.
By pre-baking your dependencies, you don't just get reliability; you get speed—eliminating the wasted minutes of running apt-get on every single job.
Ready to lock down your environment and debug CI failures locally in minutes?
