Learning Windows Server Containers

Overview of this book

Windows Server Containers are independent, isolated, manageable and portable application environments which are light weight and shippable. Decomposing your application into smaller manageable components or MicroServices helps in building scalable and distributed application environments. Windows Server Containers have a significant impact on application developers, development operations (DevOps) and infrastructure management teams. Applications can be built, shipped and deployed in a fast-paced manner on an easily manageable and updatable environment. Learning Windows Server Containers teaches you to build simple to advanced production grade container based application using Asp.Net Core, Visual Studio, Azure, Docker and PowerShell technologies. The book teaches you to build and deploy simple web applications as Windows and Hyper-V containers on Windows 10 and Windows Server 2016 on Azure. You will learn to build on top of Windows Container Base OS Images, integrate with existing images from Docker Hub, create custom images and publish to Hub. You will also learn to work with storage containers built using Volumes and SQL Server as container, create and configure custom networks, integrate with Redis Cache containers, configure continuous integration and deployment pipelines using VSTS and Git Repository. Further you can also learn to manage resources for a container, setting up monitoring and diagnostics, deploy composite container environments using Docker Compose on Windows and manage container clusters using Docker Swarm. The last chapter of the book focuses on building applications using Microsoft’s new and thinnest server platform – Nano Servers.

Preface

Networking modes


Windows Containers can use any of the four available networking modes (or drivers) to expose containers to the outside world. The networking mode chosen by the container decides how the container will be accessible from outside, how IP addresses are assigned and how networking policy can be applied. Apart from NAT networking mode, we've learned that the Windows Server 2016 networking stack offers three more modes for networking: transparent, L2 bridge and L2 tunnel. These are described in the next section.

Transparent

In transparent networking mode, each container is directly connected to the host's network (unlike NAT where containers use container host's IP to connect to the outside network). This mode is most familiar to Hyper-V users. Containers use the VM switch to connect to the network connected by the switch as shown in the following image:

Traffic is routed from the containers to the NIC via the v-Switch directly. Containers can be assigned IP addresses statically...
