wtf is docker-haskell-platform?

This project gives you a ready-to-use environment for Haskell, a programming language known for being mathematically precise and strongly typed. Instead of dealing with the headache of manually installing all the necessary tools and libraries on your own computer, you can use this to get a pre-packaged setup running almost instantly. It's essentially a digital shipping container that comes preloaded with everything you need to start writing and running Haskell code. It works by using Docker, a tool that bundles software into isolated, predictable units called "containers." This repository provides the instructions (called Dockerfiles) that tell Docker exactly how to download and set up a specific version of the Haskell platform. It offers two flavors: a "plain" version with the standard set of tools, and an updated version that includes a newer package manager called cabal-install, which helps you pull in extra code libraries that aren't included by default. This would be useful for a developer or a student who wants to learn Haskell without fighting with installation problems, or a team that needs to ensure everyone is working in the exact same software environment. For example, if you are following a tutorial written for an older version of Haskell, you can use this to instantly get a matching setup. If you just want to experiment with the language on your laptop without permanently modifying your system, this provides a safe, disposable sandbox. One notable thing about the project is its age. It specifically targets the 2013.2.0.0 release of the Haskell platform. While this makes it a great snapshot for running older code or following vintage tutorials, it is likely not the right choice if you want to build modern applications using the latest features of the language.
