I’ll be using the iximiuz Golang environment in this post, making it easier for readers to follow the exercises.

As Liz Rice mentions in each lesson, our goal is to mimic Docker’s run command so that an application can run in an environment isolated from the host (aka a container). However, note that we won’t be pulling a public image—instead, we’ll use the Ubuntu 24.04 rootfs as the container’s file system.
Therefore, we’ll use Golang to build a small program that provides a capability similar to docker run.
Capture from Liz Rice’s materials
As we enhance the functionality of our small program, we will explore the following topics, allowing us to create a basic simulation of a non-production container environment.
