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 DevSecOps into the pipeline using Aqua Security

The Shift Left approach to DevOps Security is becoming increasingly popular, which means that security must be built into the process and pipeline. One of the biggest problems with shortened pipelines is that they often leave little room for proper security checks. Due to this, another approach called deploy changes as quickly as possible was introduced, which is key to the success of DevOps.

In this section, we will cover automating vulnerability checks in container images using Aqua Security to reduce the application attack surface.

Getting ready

Make sure you have an existing CI/CD pipeline configured using your preferred CI/CD tool. If not, follow the instructions in Chapter 3, Building CI/CD Pipelines, to configure GitLab or CircleCI.
