7. Agenda
• Windows Server 2016
• Building and deploying Windows Containers
• Differences to Linux
• Hyper-V Containers
• Docker API / Kubernetes / Swarm
• Future

9. http://www.infoworld.com/article/3072929/linux/containers-101-linux-containers-and-docker-explained.html

10. Containers are not Virtual Machines
Think of Docker more as a process
management

11. Docker - An open platform for distributed
applications for developers and sysadmins.

12. Batteries included but removable

13. Three Key Concepts
• Docker Containers – Running Processes
• Docker Images – “Layered Zip Files”
• Docker Registry – Where Images are stored

21. Windows Server Core
• Nearly Win32 Compatible
• Same behaviour of Windows
• Install all of the same tooling

22. Windows Nano
• Stripped down
• Smallest footprint
• 1/20th the size of Windows Server Core
• Only essential components
– Hyper-V, Clustering, Networking, Storage, .Net,
Core CLR

23. Windows Server Core => Ubuntu Linux
Windows Nano => Alpine Linux
Windows Server Core => Legacy Apps?
Windows Nano => Modern Apps?

24. Installing Windows Containers

25. > Install-Module -Name DockerMsftProvider
-Repository PSGallery -Force
> Install-Package -Name docker
-ProviderName DockerMsftProvider
> Restart-Computer -Force

28. Layered Zip File

29. Windows Linux Subsystem
• Completely unrelated
• Maybe not in the future…

30. What is a Windows Docker Image?

31. PS C:> docker images
REPOSITORY TAG IMAGE ID CREATED
windowsservercore 10.0.10586.0 6801d964fda5 2 weeks ago
windowsservercore latest 6801d964fda5 2 weeks ago
nanoserver 10.0.10586.0 8572198a60f1 2 weeks ago
nanoserver latest 8572198a60f1 2 weeks ago

32. PS C:> docker run -it
windowsservercore cmd
Thank you to https://msdn.microsoft.com/en-

33. SSMS

34. Building Windows based Docker
Images

41. Latest Tag
• Official images have a convention of :latest
• Using :latest can introduces problems
• Use CI build number / Semver

84. How is this different to Linux?

85. Kernel Virtualisation

88. Windows Hyper-V Isolation

89. Windows Hyper-V Isolation
• Problem: Shared Kernel
• Solution: Super lightweight virtual machines
• Intel Clear Containers
• Ubuntu LXD
• IBM are working on something

90. PS C:> docker run -it -p 80:80
--isolation=hyperv app cmd
1) Windows starts 'Utility VM‘ and freezes state
2) Forks VM state, brings up a fresh second VM
3) Launches container on VM

91. Properties of Windows Utility VM
• Invisible to Docker and containers
• All writes are degraded
• Separate Kernel to host
• SMB file share to access host data
• In the future used for Linux containers?

92. What about developers?

94. Install Containers Support on Windows 10
> Enable-WindowsOptionalFeature -Online -FeatureName containers -All
> Enable-WindowsOptionalFeature -Online -FeatureName Microsoft-Hyper-V -All
> Restart-Computer -Force
> Invoke-WebRequest "https://test.docker.com/builds/Windows/x86_64/docker-1.13.0.zip" -OutFile
"$env:TEMPdocker-1.13.0-rc4.zip" -UseBasicParsing
> Expand-Archive -Path "$env:TEMPdocker-1.13.0.zip" -DestinationPath $env:ProgramFiles
> dockerd --register-service
> Start-Service Docker

98. Running Containers in Production

99. Swarm

101. Constraint Scheduler

-e constraint:ostypelabel==linuxcompat
ubuntu bash

103. Microsoft, Apprenda, Red Hat

104. Mesosphere DC/OS
Powering Azure Container Service

105. Host Fingerprinting
• Constraints based deployment
• Container is based on Nano Server, within
cluster, deploy to server capable of running
Nano Server (ie. Windows Server 2016)Host Fingerprinting

107. Azure Container Service

109. The Future?

111. SQL Server as a Container

112. Visual Studio as a Container?

113. Everything as a Container

114. Deploy Anywhere
