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.

Setting up a CI/CD pipeline using GitHub Actions

GitHub Actions enable you to create custom software development workflows directly in your GitHub repository. If you are already using GitHub as your code repository, built-in CI/CD capabilities make this option very compelling.

In this section, we will cover the GitHub Actions workflow configuration and built-in CI/CD capabilities. You will learn how to manage workflows and create new GitHub Actions.

Getting ready

In the following recipe, you will learn how to create a basic action example in a repository you own by adding a Dockerfile. This recipe requires an active GitHub account with a project to build. We will use AWS EKS to demonstrate CI with GitHub.

How to do it...

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

  • Creating a workflow file
  • Creating a basic Docker build workflow
  • Building and publishing images to Docker Registry
  • Adding a workflow status badge
