What is minimal-docker-golang?

minimal-docker-golang is a simple example project that shows how to take a small program, package it up, and run it in a safe, isolated space called a "sandbox." The main benefit is security: you can run a program on a file without worrying that the program will mess with anything else on your computer. It is a clean, minimal demonstration of how to safely execute code in a controlled environment. The project uses two tools working together. First, it uses Go, a programming language that compiles your code into a single, self-contained program file with no extra pieces needed. Second, it uses Docker, a tool that creates a lightweight, sealed-off container where the program runs. By combining them, you get a program that is easy to move around and guaranteed to run in a space where it cannot access your files, network, or system settings unless you explicitly allow it. This project is aimed at developers who want to learn the basics of sandboxing or who need a starting point for running untrusted code safely. For example, if you are building a coding education platform where users submit their own code to be graded, you need a way to run that code without risking your server. A teacher grading a student's script could use this setup to run the script on a test file, knowing the script cannot accidentally delete other files on the machine. It serves as a practical template for that kind of isolated execution. What is notable about the project is how stripped-down it is. Instead of pulling in complex frameworks or configuration files, it relies on Go's built-in independence and Docker's native isolation. This makes it a useful, readable starting point for understanding the mechanics of sandboxed execution before adding more complex features.
