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.

Summary

We covered the following topics in this chapter:

  • Docker volumes can be used to share folders or files from the host with the container(s).
  • Containers can share volumes using named volumes or -volumes-from flag.
  • Applications using shared volumes should make ensure that multiple containers do not write to a shared file at once or else the data might end up corrupted.
  • Relational databases can also be run and configured as containers.
  • Volumes attached to a container in running state cannot be deleted. The container should be stopped first to delete the volume.
  • Multiple volumes can be attached to one container.
  • VOLUME is a Dockerfile instruction which can be used to create volumes as part of the build process.
  • Microsoft provides a container image for SQL Server Express 2016 and 2014 which can be readily used.
  • We can use Azure storage for Azure container hosts or storage spaces for on-premises container hosts while using database containers to configure scalable storages.
