Kubernetes Cookbook - Second Edition

By: Hideto Saito, Hui-Chuan Chloe Lee, Ke-Jou Carol Hsu

Overview of this book

Kubernetes is an open source orchestration platform to manage containers in a cluster environment. With Kubernetes, you can configure and deploy containerized applications easily. This book gives you a quick brush up on how Kubernetes works with containers, and an overview of main Kubernetes concepts, such as Pods, Deployments, Services and etc. This book explains how to create Kubernetes clusters and run applications with proper authentication and authorization configurations. With real-world recipes, you'll learn how to create high availability Kubernetes clusters on AWS, GCP and in on-premise datacenters with proper logging and monitoring setup. You'll also learn some useful tips about how to build a continuous delivery pipeline for your application. Upon completion of this book, you will be able to use Kubernetes in production and will have a better understanding of how to manage containers using Kubernetes.

Using AWS as Kubernetes Cloud Provider

From Kubernetes 1.6, Cloud Controller Manager (CCM) was introduced, which defines a set of interfaces so that different cloud providers could evolve their own implementations out of the Kubernetes release cycle. Talking to the cloud providers, you can't ignore the biggest player: Amazon Web Service. According to the Cloud Native Computing Foundation, in 2017, 63% of Kubernetes workloads run on AWS. AWS CloudProvider supports Service as Elastic Load Balancer (ELB) and Amazon Elastic Block Store (EBS) as StorageClass.

At the time this book was written, Amazon Elastic Container Service for Kubernetes (Amazon EKS) was under preview, which is a hosted Kubernetes service in AWS. Ideally, it'll have better integration with Kubernetes, such as Application Load Balancer (ALB) for Ingress, authorization, and networking. Currently in AWS,...
