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.

Deploying and managing the life cycle of GitLab

GitLab is a complete DevOps tool chain, delivered in a single application platform. GitLab provides all the necessary tooling you need to manage, plan, create, verify, package, release, configure, monitor, and secure your applications.

In this section, we will cover the deployment and life cycle management of GitLab using Helm charts.

Getting ready

In the following recipe, you will learn how to install GitLab on an existing Kubernetes cluster where you can manage the entire DevOps life cycle.

This recipe requires kubectl and Helm, as well as an existing Kubernetes cluster. For this recipe, we will use the cluster we deployed on AWS in Chapter 1, Building Production-Ready Kubernetes Clusters. You should be able to run the same recipe on any Kubernetes cluster version 1.11 or higher with a minimum of 6vCPU and 16 GB of RAM.
