Many people use container systems like Docker, but how do they work? What do people mean when they mention cgroups and namespaces, or when they describe a container as a “lightweight virtual machine”? In this course designed for the intermediate level programmer (any language), you'll discover exactly what a container is by writing one with a surprisingly small amount of Go code. Along the way, you'll lose your fear of syscalls and learn that a container is really just a Linux process with its view of the world limited through namespaces, cgroups, and chroot. Gain an in-depth understanding of what containers are and how they workLearn how to build your own container engine using GoMaster the ability to run containers with confidenceLiz Rice is a technology evangelist for Acqua Security, the CEO of Microscaling Systems, and one of the developers of MicroBadger, the tool for managing container metadata.
