Kubernetes in Production Best Practices

By: Aly Saleh, Murat Karslioglu

Overview of this book

Although out-of-the-box solutions can help you to get a cluster up and running quickly, running a Kubernetes cluster that is optimized for production workloads is a challenge, especially for users with basic or intermediate knowledge. With detailed coverage of cloud industry standards and best practices for achieving scalability, availability, operational excellence, and cost optimization, this Kubernetes book is a blueprint for managing applications and services in production. You'll discover the most common way to deploy and operate Kubernetes clusters, which is to use a public cloud-managed service from AWS, Azure, or Google Cloud Platform (GCP). This book explores Amazon Elastic Kubernetes Service (Amazon EKS), the AWS-managed version of Kubernetes, for working through practical exercises. As you get to grips with implementation details specific to AWS and EKS, you'll understand the design concepts, implementation best practices, and configuration applicable to other cloud-managed services. Throughout the book, you’ll also discover standard and cloud-agnostic tools, such as Terraform and Ansible, for provisioning and configuring infrastructure. By the end of this book, you’ll be able to leverage Kubernetes to operate and manage your production environments confidently.

Creating the network infrastructure

In Chapter 2, Architecting Production-Grade Kubernetes Infrastructure, you learned in detail about the infrastructure architecture design recommendations and the technical decisions that you should take in relation to the production readiness state for your Kubernetes clusters. In this section, you will use Terraform to provision the network layer of your Kubernetes production infrastructure.

These are the AWS network resources that you will provision with the Terraform code in this section:

  • AWS VPC
  • Private subnets
  • Public subnets
  • Route tables
  • Internet and NAT gateways

Encapsulating AWS resources into reusable code modules is a recommended IaC practice. In the next subsection, you will create a VPC Terraform module that includes the previous AWS resources. You can then reuse this module with no code changes to provision VPCs for as many Kubernetes clusters as you need.
