Getting Started with Containerization

Overview of this book

Kubernetes is an open source orchestration platform for managing containers in a cluster environment. This Learning Path introduces you to the world of containerization, in addition to providing you with an overview of Docker fundamentals. As you progress, you will be able to understand how Kubernetes works with containers. Starting with creating Kubernetes clusters and running applications with proper authentication and authorization, you'll learn how to create high-availability Kubernetes clusters on Amazon Web Services (AWS), and also learn how to use kubeconfig to manage different clusters. Whether it is learning about Docker containers and Docker Compose, or building a continuous delivery pipeline for your application, this Learning Path will equip you with all the right tools and techniques to get started with containerization. By the end of this Learning Path, you will have gained hands-on experience of working with Docker containers and orchestrators, including SwarmKit and Kubernetes. This Learning Path includes content from the following Packt products: • Kubernetes Cookbook - Second Edition by Hideto Saito, Hui-Chuan Chloe Lee, and Ke-Jou Carol Hsu • Learn Docker - Fundamentals of Docker 18.x by Gabriel N. Schenker

Chapter 1. What Are Containers and Why Should I Use Them?

This first chapter of this book will introduce you to the world of containers and their orchestration. The book starts from the beginning, assuming no prior knowledge in the area of containers, and will give you a very practical introduction into the topic.

 

 

In this chapter, we are focusing on the software supply chain and the friction within it. We then present containers as a means to reduce this friction and add enterprise-grade security on top of it. In this chapter, we also look into how containers and the ecosystem around them are assembled. We specifically point out the distinction between the upstream Operations Support System (OSS) components, united under the code name Moby, that form the building blocks of the downstream products of Docker and other vendors.

The chapter covers the following topics:

  • What are containers?
  • Why are containers important?
  • What's the benefit for me or for my company?
  • The Moby project
  • Docker products
  • The container ecosystem
  • Container architecture 

After completing this module, you will be able to:

  • Explain in a few simple sentences to an interested layman what containers are, using an analogy such as physical containers
  • Justify to an interested layman why containers are so important, using an analogy such as physical containers versus traditional shipping, or apartment homes versus single family homes, and so on
  • Name at least four upstream open source components that are used by the Docker products, such as Docker for Mac/Windows
  • Identify at least three Docker products
