Kubernetes – An Enterprise Guide - Second Edition

By: Marc Boorshtein, Scott Surovich

Overview of this book

Kubernetes has taken the world by storm, becoming the standard infrastructure for DevOps teams to develop, test, and run applications. With significant updates in each chapter, this revised edition will help you acquire the knowledge and tools required to integrate Kubernetes clusters in an enterprise environment. The book introduces you to Docker and Kubernetes fundamentals, including a review of basic Kubernetes objects. You’ll get to grips with containerization and understand its core functionalities such as creating ephemeral multinode clusters using KinD. The book has replaced PodSecurityPolicies (PSP) with OPA/Gatekeeper for PSP-like enforcement. You’ll integrate your container into a cloud platform and tools including MetalLB, externalDNS, OpenID connect (OIDC), Open Policy Agent (OPA), Falco, and Velero. After learning to deploy your core cluster, you’ll learn how to deploy Istio and how to deploy both monolithic applications and microservices into your service mesh. Finally, you will discover how to deploy an entire GitOps platform to Kubernetes using continuous integration and continuous delivery (CI/CD).

    1. You can't – there is no way to add anything in front of NFS to present S3.
    2. Kubernetes can do this using native CSI features.
    3. Install MinIO and use the NFS volumes as persistent disks in the deployment.
    4. You don't need to use an object store; you can use NFS directly with Velero.
  3. True or false – Velero backups can only be restored on the same cluster where the backup was originally created.
    1. True
    2. False
  4. What utility can you use to create an etcd backup?
    1. Velero.
    2. MinIO.
    3. There is no reason to back up the etcd database.
    4. etcdctl.
  5. Which...
