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 12: Development Workflow with Kubernetes

  1. Helm is used to create redistributable packages for your Kubernetes application. You can use it to deploy applications provided by others or use it for your own applications as an internal package and dependency manager for microservices in your system.
  2. Helm 2 required a dedicated service deployed on Kubernetes named Tiller, which was responsible for actual communication with Kubernetes API. This has caused various problems, including security and RBAC issues. As of Helm 3.0.0, Tiller is no longer needed and chart management is done by the client.
  3. Use a Kubernetes Job object as a post-installation hook in Helm.
  4. Use a new Docker image in the Helm chart manifest or values file and perform helm upgrade.
  5. The Snapshot Debugger is a feature of Azure Application Insights that monitors exception telemetry from your application, including...
