Containers are not Virtual Machines
Think of Docker more as a process management
Docker - An open platform for distributed applications for developers and sysadmins.
Batteries included but removable
Three Key Concepts• Docker Containers – Running Processes
• Docker Images – “Layered Zip Files”
• Docker Registry – Where Images are stored

Docker Engine
Windows Server Core• Nearly Win32 Compatible• Same behaviour of Windows• Install all of the same tooling
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
Windows Server Core => Ubuntu Linux
Windows Nano => Alpine Linux
Windows Server Core => Legacy Apps?
Windows Nano => Modern Apps?
Installing Windows Containers

Layered Zip File
Windows Linux Subsystem• Completely unrelated• Maybe not in the future…
What is a Windows Docker Image?

Building Windows based Docker Images
Latest Tag• Official images have a convention of :latest
• Using :latest can introduces problems
• Use CI build number / Semver

How is this different to Linux?

Windows Hyper-V Isolation
Windows Hyper-V Isolation• Problem: Shared Kernel• Solution: Super lightweight virtual machines
• Intel Clear Containers• Ubuntu LXD• IBM are working on something
PS C:\> docker run -it -p 80:80 \ --isolation=hyperv app cmd
1) Windows starts 'Utility VM‘ and freezes state2) Forks VM state, brings up a fresh second VM3) Launches container on VM
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?
What about developers?

Powering Azure Container Service
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
Azure Container Service
The Future?
SQL Server as a Container
Visual Studio as a Container?
Everything as a Container
Deploy Anywhere
