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

Chapter 10. Manage Resource Allocation and REST API

Windows Containers is a virtualization platform. Like any other virtualization platform, it comes with its own share of challenges: one such issue is managing resource utilization. Containers are a critical step towards maximizing resource utilization; but at the same time is very important to draw a line between how much CPU or memory a container can utilize on a shared environment. If there is no medium to control the resource usage, the few systems might exploit the shared infrastructure leading to errors or failures to other systems sharing the same infrastructure. In this chapter, we will learn how to manage the resource allocation of Windows Containers within a host. We will also learn how to use the Docker REST API to control and manage Windows Containers on Windows Server 2016. We have been using the Docker command line so far to build and run containers, but for some category of users it is a suboptimal way of handling systems...
