Introduction

In this self-paced tutorial, you will gain a basic understanding of the moving parts that make up the typical container architecture. This will cover container images, registries, hosts, and orchestration.

By the end of this lab you should be able to:

Draw a diagram showing how the Linux kernel, services and daemons work together to create and deploy containers
Internalize how the architecture of the kernel and supporting services affect security and performance
Explain the API interactions of daemons and the host kernel to create isolated processes
Understand the basics of why people move on to container orchestration
Command the nomenclature necessary to technically discuss the basics of the single and multi-host toolchain

Outline

Container Images: made up of underlying operating system components like libraries and programming languages
Container Registries: Fancy file servers that help users share container images
Container Hosts: Includes Podman (or Docker) runtime, Systemd, runc, and Libcontainer
Container Orchestration: Includes Kubernetes/OpenShift
