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.

Building event-driven automation with StackStorm

StackStorm is an open source, event-driven automation platform. Using the GitOps approach, it helps run workflows based on events. In this section, we will perform arbitrary automation or remediation tasks using StackStorm on Kubernetes. You will learn how to deploy StackStorm in a highly available configuration on Kubernetes using Helm charts and get started by deploying examples of rules, custom sensors, actions, and workflows.

Getting ready

Make sure you have a Kubernetes cluster ready, as well as kubectl and helm configured so that you can manage the cluster resources.

How to do it…

This section is further divided into the following subsections to make this process easier:

  • Installing StackStorm
  • Accessing the StackStorm UI
  • Using the st2 CLI
  • Defining a rule
  • Deploying a rule

Installing StackStorm

Although StackStorm can be distributed as a Red Hat Package Manager/Debian (RPM/Deb) for Linux systems and as Docker images, if you...
