+# Windows Containers
+
+![Container with Windows](images/windows-containers.jpg)
+
+---
+
+## Objectives
+
+At the end of this section, you will be able to:
+
+* Understand Windows Container vs. Linux Container.
+
+* Know about the features of Docker for Windows for choosing architecture.
+
+* Run other container architectures via QEMU emulation.
+
+---
+
+## Are containers *just* for Linux?
+
+Remember that a container must run on the kernel of the OS it's on.
+
+- This is both a benefit and a limitation.
+ 
+  (It makes containers lightweight, but limits them to a specific kernel.)
+ 
+- At its launch in 2013, Docker did only support Linux, and only on amd64 CPUs.
+
+- Since then, many platforms and OS have been added.
+
+  (Windows, ARM, i386, IBM mainframes ...  But no macOS or iOS yet!)
+
+--
+
+- Docker Desktop (macOS and Windows) can run containers for other architectures
+
+  (Check the docs to see how to [run a Raspberry Pi (ARM) or PPC container](https://docs.docker.com/docker-for-mac/multi-arch/)!)
+
+---
+
+## History of Windows containers
+
+- Early 2016, Windows 10 gained support for running Windows binaries in containers.
+
+  - These are known as "Windows Containers"
+  
+  - Win 10 expects Docker for Windows to be installed for full features
+
+  - These must run in Hyper-V mini-VM's with a Windows Server x64 kernel 
+
+  - No "scratch" containers, so use "Core" and "Nano" Server OS base layers
+
+  - Since Hyper-V is required, Windows 10 Home won't work (yet...)
+
+--
+
+- Late 2016, Windows Server 2016 ships with native Docker support
+
+  - Installed via PowerShell, doesn't need Docker for Windows
+
+  - Can run native (without VM), or with [Hyper-V Isolation](https://docs.microsoft.com/en-us/virtualization/windowscontainers/manage-containers/hyperv-container)
+
+---
+
+## LCOW (Linux Containers On Windows)
+
+While Docker on Windows is largely playing catch up with Docker on Linux,
+it's moving fast; and this is one thing that you *cannot* do on Linux!
+
+- LCOW came with the [2017 Fall Creators Update](https://blog.docker.com/2018/02/docker-for-windows-18-02-with-windows-10-fall-creators-update/).
+
+- It can run Linux and Windows containers side-by-side on Win 10.
+
+- It is no longer necessary to switch the Engine to "Linux Containers".
+
+  (In fact, if you want to run both Linux and Windows containers at the same time,
+   make sure that your Engine is set to "Windows Containers" mode!)
+
+--
+
+If you are a Docker for Windows user, start your engine and try this:
+
+```bash
+docker pull microsoft/nanoserver:1803
+```
+
+(Make sure to switch to "Windows Containers mode" if necessary.)
+
+---
+
+## Run Both Windows and Linux containers
+
+- Run a Windows Nano Server (minimal CLI-only server)
+
+  ```bash
+  docker run --rm -it microsoft/nanoserver:1803 powershell
+  Get-Process
+  exit
+  ```
+
+- Run busybox on Linux in LCOW
+
+  ```bash
+  docker run --rm --platform linux busybox echo hello
+  ```
+
+(Although you will not be able to see them, this will create hidden
+Nano and LinuxKit VMs in Hyper-V!)
+
+---
+
+## Did We Say Things Move Fast
+
+- Things keep improving.
+
+- Now `--platform` defaults to `windows`, some images support both:
+
+  - golang, mongo, python, redis, hello-world ... and more being added
+
+  - you should still use `--plaform` with multi-os images to be certain 
+
+- Windows Containers now support `localhost` accessable containers (July 2018)
+
+- Microsoft (April 2018) added Hyper-V support to Windows 10 Home ...
+
+  ... so stay tuned for Docker support, maybe?!?
+
+---
+
+## Other Windows container options
+
+Most "official" Docker images don't run on Windows yet.
+
+Places to Look:
+
+  - Hub Official: https://hub.docker.com/u/winamd64/ 
+  
+  - Microsoft: https://hub.docker.com/r/microsoft/

+
+## SQL Server? Choice of Linux or Windows
+
+- Microsoft [SQL Server for Linux 2017](https://hub.docker.com/r/microsoft/mssql-server-linux/) (amd64/linux)
+
+- Microsoft [SQL Server Express 2017](https://hub.docker.com/r/microsoft/mssql-server-windows-express/) (amd64/windows)
+
+---
+
+## Windows Tools and Tips
+
+- PowerShell [Tab Completion: DockerCompletion](https://github.com/matt9ucci/DockerCompletion)
+
+- Best Shell GUI: [Cmder.net](http://cmder.net/)
