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 6: Interacting with Kubernetes Clusters

  1. kubectl uses the kubeconfig file, which is located in ~\.kube\config. This YAML configuration file contains all of the parameters required for kubectl to connect to the Kubernetes API for your cluster
  2. You can use a KUBECONFIG environment variable or the --kubeconfig flag for individual commands to force kubectl to use a different kubeconfig.
  3. Contexts are used for organizing and coordinating access to multiple Kubernetes clusters.

  1. kubectl create is an imperative command to create new API resources, whereas kubectl apply is a declarative management command for managing API resources.
  2. kubectl patch updates a resource by merging the current resource state and a patch that contains only the modified properties. A common use case for patching is when you need to enforce a node selector for an existing DaemonSet in hybrid Linux/Windows...
