Containers From Scratch

What is a container? Is it really a “lightweight VM”? What are namespaces and control groups? What does a host machine know about my containers? And what do my containers know about each other?

In this talk Liz will live-code a container in a few lines of Go code, to answer all these questions and more, and show you exactly what’s happening under the covers when you run a container.

This talk is based on Liz’s top-rated DockerCon session “What have namespaces done for you lately?”, with updates and additions for 2018.

Prerequisite knowledge:
So long as you’re reasonably comfortable running the Linux command ps, you’ll be fine!
