Kubernetes and Docker - An Enterprise Guide

Overview of this book

Containerization has changed the DevOps game completely, with Docker and Kubernetes playing important roles in altering the flow of app creation and deployment. This book will help you acquire the knowledge and tools required to integrate Kubernetes clusters in an enterprise environment. The book begins by introducing you to Docker and Kubernetes fundamentals, including a review of basic Kubernetes objects. You’ll then get to grips with containerization and understand its core functionalities, including how to create ephemeral multinode clusters using kind. As you make progress, you’ll learn about cluster architecture, Kubernetes cluster deployment, and cluster management, and get started with application deployment. Moving on, you’ll find out how to integrate your container to a cloud platform and integrate tools including MetalLB, externalDNS, OpenID connect (OIDC), pod security policies (PSPs), Open Policy Agent (OPA), Falco, and Velero. Finally, you will discover how to deploy an entire platform to the cloud using continuous integration and continuous delivery (CI/CD). By the end of this Kubernetes book, you will have learned how to create development clusters for testing applications and Kubernetes components, and be able to secure and audit a cluster by implementing various open-source solutions including OpenUnison, OPA, Falco, Kibana, and Velero.

  1. Correct answer: (D) falco_rules.local.yaml. Any changes to rules that have been customized to your installation should go in your falco_rules.changes.yaml file. You should not edit the include set of rules, which are part of falco_rules.yaml. The falco.yaml file is the base Falco configuration file and does not contain any rules.
  2. Correct answer: (B) FluentD. There are many forwarders that are compatible with Kubernetes, but one of the most commonly used forwarders is FluentD.
  3. Correct answer: (C) Kibana. The EFK stack includes ElasticSearch, FluentD, and Kibana. Kibana is the component that provides visualizations and dashboards for your logs.
  4. Correct answer: (B) Falcosidekick. The Falcosidekick utility only forwards Falco logs to a central logging server.
  5. Correct answer: (A) Lists. You can group a collection of items in Falco using Lists.
