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 2: Managing State in Containers

  1. The container layer is the top writeable layer in the filesystem for each Docker container.
  2. Bind mounts provide a simple functionality of mounting any file or directory from the container host to a given container. Volumes provide similar functionality but they are fully managed by Docker, so you do not have to worry about physical paths in the container host filesystem.

  1. The writeable container layer is coupled with the container host, which means it is not possible to easily move the data to a different host. Layer filesystems provide worse performance than direct access to the host filesystem (for example, using volumes). You cannot share the writeable layer between different containers.
  2. Use the SMB Global Mapping feature on Windows host, which is provided to mount SMB shares visible to the containers. Then, you can mount the SMB...
