Hands-On Kubernetes on Windows

By: Piotr Tylenda

Overview of this book

With the adoption of Windows containers in Kubernetes, you can now fully leverage the flexibility and robustness of the Kubernetes container orchestration system in the Windows ecosystem. This support will enable you to create new Windows applications and migrate existing ones to the cloud-native stack with the same ease as for Linux-oriented cloud applications. This practical guide takes you through the key concepts involved in packaging Windows-distributed applications into containers and orchestrating these using Kubernetes. You'll also understand the current limitations of Windows support in Kubernetes. As you advance, you'll gain hands-on experience deploying a fully functional hybrid Linux/Windows Kubernetes cluster for development, and explore production scenarios in on-premises and cloud environments, such as Microsoft Azure Kubernetes Service. By the end of this book, you'll be well-versed with containerization, microservices architecture, and the critical considerations for running Kubernetes in production environments successfully.

Chapter 15: Disaster Recovery

  1. The main difference between DR and BC is that DR focuses on getting the infrastructure up and running following an outage, whereas BC covers keeping the business scenarios running during a major incident.
  2. The etcd cluster is used by the master and persistent volumes are used by Pods.
  3. A snapshot is a backup file provided by the v3 API of etcd.
  4. Velero can perform etcd snapshots, manage them in external storage, and restore if needed. Additionally, it can be used for performing backups of persistent volumes using Restic integration. Etcd-operator is used for provisioning of multiple etcd clusters on top of Kubernetes. You can easily manage the etcd clusters and perform backup-restore operations. Use this approach if you plan to manage multiple Kubernetes clusters in your environment.
  5. Access all Kubernetes master nodes and, on all machines, perform...
