Docker is sorta like portable software, but think of it like making your entire development environment (your framework and all dependent libraries, web/database servers, even the OS) portable. Better yet, instead of downloading and unzipping to a folder, you can just run a simple command to get up and running -- it really can't get simpler than that in terms of setting up a development environment. After you "dockerize" for the first time, going back to copying configuration files and what not will feel so archaic. One warning though: Docker consumes memory like it's bottled water after being in the desert for a month. My 8GB system went from 35% memory consumption to over 60% memory consumption by using Docker. I recommend a machine with 16GB RAM if you plan to use Docker full-time.
Great for development on multiple different systems
