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

Summary


In this chapter, we have introduced Docker Swarm, which, next to Kubernetes, is the second most popular orchestrator for containers. We have looked into the architecture of a swarm, discussed all the types of resources running in a swarm, such as services, tasks, and more, and we have created services in the swarm and deployed an application that consists of multiple related services.

In the next chapter, we are going to explore how to deploy services or applications onto a Docker Swarm with zero downtime and automatic rollback capabilities. We are also going to introduce secrets as a means to protect sensitive information.
