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

Docker tags


Tagging helps developers to version images. An image can contain any number of tags. Developers or operators using the image can download/pull a particular version using the tag name. A tag name can consist of numbers, lowercase or uppercase alphabets, underscores, periods, and dashes. The following command creates a new image with v1.0 as the tag name and learningwsc/mycustomwebserver as the image name where learningwsc is the Docker Hub username and mycustomwebserver is the name of my image:

docker build -t learningwsc/mycustomwebserver:v1.0 .

The Docker daemon is intelligent enough to avoid downloads of redundant layers when working with multiple tags of the same image. When the users download the image with a tag, docker checks for existing layers on the host machine and the differential set of the image, or say only the latest layers are downloaded, this makes software really thin and easily portable.

If not specified the latest is used as the default tag. Tagging information...
