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

About Packt


In this chapter, we have learned about how containers running on a single host can communicate with each other. First, we looked at the CNM that defines the requirements of a container network and then we looked at several implementations of the CNM, such as the bridge network. We then looked at how the bridge network functions in detail and also what kind of information Docker provides us with about the networks and the containers attached to those networks. We also learned about adopting two different perspectives, from both outside and inside the container.

In the next chapter, we're going to introduce Docker Compose. We will learn about creating an application that consists of multiple services, each running in a container, and how Docker Compose allows us to easily build, run, and scale such an application using a declarative approach.
