Overview of this book

With its broad adoption across various industries, Kubernetes is helping engineers with the orchestration and automation of container deployments on a large scale, making it the leading container orchestration system and the most popular choice for running containerized applications. This Kubernetes book starts with an introduction to Kubernetes and containerization, covering the setup of your local development environment and the roles of the most important Kubernetes components. Along with covering the core concepts necessary to make the most of your infrastructure, this book will also help you get acquainted with the fundamentals of Kubernetes. As you advance, you'll learn how to manage Kubernetes clusters on cloud platforms, such as Amazon Web Services (AWS), Microsoft Azure, and Google Cloud Platform (GCP), and develop and deploy real-world applications in Kubernetes using practical examples. Additionally, you'll get to grips with managing microservices along with best practices. By the end of this book, you'll be equipped with battle-tested knowledge of advanced Kubernetes topics, such as scheduling of Pods and managing incoming traffic to the cluster, and be ready to work with Kubernetes on cloud platforms.

The sidecar design pattern

The sidecar design pattern is an extremely useful one. It is good for when you want to extend the features of your main containers with features it would normally not be able to achieve on its own.

Just like we did for the ambassador container, we're going to explain exactly what it is by covering some examples. Then, we're going to discover some concrete examples.

What is the sidecar design pattern?

Think of the sidecar container as an extension or a helper for your main container. Its main purpose is to extend the main container to bring it a new feature, but without changing anything about it. Unlike the ambassador design pattern, the main container may even not be aware of the presence of a sidecar.

Just like the ambassador design pattern, the sidecar design pattern makes use of at least two containers:

  • The main container, the one that is running the application
  • The sidecar container, the one that is bringing something...
