Kubernetes - A Complete DevOps Cookbook

By: Murat Karslioglu

Overview of this book

Kubernetes is a popular open source orchestration platform for managing containers in a cluster environment. With this Kubernetes cookbook, you’ll learn how to implement Kubernetes using a recipe-based approach. The book will prepare you to create highly available Kubernetes clusters on multiple clouds such as Amazon Web Services (AWS), Google Cloud Platform (GCP), Azure, Alibaba, and on-premises data centers. Starting with recipes for installing and configuring Kubernetes instances, you’ll discover how to work with Kubernetes clients, services, and key metadata. You’ll then learn how to build continuous integration/continuous delivery (CI/CD) pipelines for your applications, and understand various methods to manage containers. As you advance, you’ll delve into Kubernetes' integration with Docker and Jenkins, and even perform a batch process and configure data volumes. You’ll get to grips with methods for scaling, security, monitoring, logging, and troubleshooting. Additionally, this book will take you through the latest updates in Kubernetes, including volume snapshots, creating high availability clusters with kops, running workload operators, new inclusions around kubectl and more. By the end of this book, you’ll have developed the skills required to implement Kubernetes in production and manage containers proficiently.

Managing the cost of resources using Kubecost

In this section, we will install and configure the open source Kubecost project, which gives you cost-related visibility into your Kubernetes resources. You will learn how to monitor resource costs to reduce spending and potentially prevent resource-based outages.

Getting ready

This recipe requires a functional Kubernetes cluster deployed on AWS or GCP. Currently, other cloud providers are not supported.

Before you can execute the commands in the following recipes, you need to have kubectl and helm installed. You can find the instructions to install Helm in Chapter 2, Operating Applications on Kubernetes, in the Deploying workloads using Helm charts section.

How to do it…

This section is further divided into the following subsections to ease the process:

  • Installing Kubecost
  • Accessing Kubecost dashboard
  • Monitoring Kubernetes resource cost allocation
