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. True or false: A pipeline must be implemented to make Kubernetes work.

    A. True

    B. False

  2. What are the minimum steps of a pipeline?

    A. Build, scan, test, and deploy

    B. Build and deploy

    C. Scan, test, deploy, and build

    D. None of the above

  3. What is GitOps?

    A. Running GitLab on Kubernetes

    B. Using Git as an authoritative source for operations configuration

    C. A silly marketing term

    D. A product from a new start-up

  4. What is the standard for writing pipelines?

    A. All pipelines should be written in YAML.

    C. JSON combined with Go.

    D. Rust.

  5. How do you deploy a new instance of a container in a GitOps model?

    A. Use kubectl to update the Deployment or StatefulSet in the namespace.

    B. Update the Deployment or StatefulSet manifest in Git, letting the GitOps controller update the objects in Kubernetes.
