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?

Kernel Virtualisation

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

Next Steps• Katacoda

• Windows Server 2016 on Azure

• Windows 10
