#WindowsContainer Host Deployment on #NanoServer #HyperV nested Virtualization

Hyper-V-Containers-Nested-Virtualization

Windows Containers on Hyper-V NanoServer nested Virtualization

Deployment Steps

Install Container Feature

The container feature can be installed on Windows Server 2016, or Windows Server 2016 Core, using Windows Server Manager or PowerShell.

To install the role using PowerShell, run the following command in an elevated PowerShell session.

Install Containers

PS C:\> Install-WindowsFeature containers

The system needs to be rebooted when the container role installation has completed.

PS C:\> shutdown /r

After the system has rebooted, use the Get-ContainerHost command to verify that the container role has successfully been installed:

Get-Containerhost

PS C:\> Get-ContainerHost

Prepare Nano Server

Deploying Nano Server involves creating a prepared virtual hard drive, which includes the Nano Server operating system, and additional feature packages. This guide quickly details preparing a Nano Server virtual hard drive, which can be used for Windows Containers.

For more information on Nano Server, and to explore different Nano Server deployment options, see the Nano Server Documentation.

Create a folder named nano.

PS C:\> New-Item -ItemType Directory c:\nano

Locate the NanoServerImageGenerator.psm1 and Convert-WindowsImage.ps1 files from the Nano Server folder, on the Windows Server Media. Copy these to c:\nano.

#Set path to Windows Server 2016 Media
PS C:\> $WindowsMedia = "C:\Users\Administrator\Downloads\WindowsServerTP4"

PS C:\> Copy-Item $WindowsMedia\NanoServer\Convert-WindowsImage.ps1 c:\nano
PS C:\> Copy-Item $WindowsMedia\NanoServer\NanoServerImageGenerator.psm1 c:\nano

Run the following to create a Nano Server virtual hard drive. The –Containers parameter indicates that the container package will be installed, and the –Compute parameter takes care of the Hyper-V package. Hyper-V is only required if Hyper-V containers will be created.

Import-Module

PS C:\> Import-Module C:\nano\NanoServerImageGenerator.psm1
PS C:\> New-NanoServerImage -MediaPath $WindowsMedia -BasePath c:\nano -TargetPath C:\nano\NanoContainer.vhdx -MaxSize 10GB -GuestDrivers -ReverseForwarders -Compute -Containers

When completed, create a virtual machine from the NanoContainer.vhdx file. This virtual machine will be running the Nano Server OS, with optional packages.

Configure Nested Virtualization

If the container host itself will be running on a Hyper-V virtual machine, and will also be hosting Hyper-V Containers, nested virtualization needs to be enabled. This can be completed with the following PowerShell command.

The virtual machines must be turned off when running this command.

PS C:\> Set-VMProcessor -VMName <container host vm> -ExposeVirtualizationExtensions $true

Configure Virtual Processors

If the container host itself will be running on a Hyper-V virtual machine, and will also be hosting Hyper-V Containers, the virtual machine will require at least two processors. This can be configured through the settings of the virtual machine, or with the following PowerShell script.

PS C:\> Set-VMProcessor –VMName <VM Name> -Count 2

Enable Hyper-V Role

If Hyper-V Containers will be deployed, the Hyper-V role needs to be enabled on the container host. If the container host is a virtual machine, ensure that nested virtualization has been enabled. The Hyper-V role can be installed on Windows Server 2016 or Windows Server 2016 Core using the following PowerShell command.

PS C:\> Install-WindowsFeature hyper-v

Create Virtual Switch

Each container needs to be attached to a virtual switch in order to communicate over a network. A virtual switch is created with the New-VMSwitch command. Containers support a virtual switch with type External or NAT.

This example creates a virtual switch with the name “Virtual Switch”, a type of NAT, and Nat Subnet of 172.16.0.0/12.

PS C:\> New-VMSwitch -Name "Virtual Switch" -SwitchType NAT -NATSubnetAddress 172.16.0.0/12

Configure NAT

In addition to creating a virtual switch, if the switch type is NAT, a NAT object needs to be created. This is completed using the New-NetNat command. This example creates a NAT object, with the name ContainerNat, and an address prefix that matches the NAT subnet assigned to the container switch.

Finally, if the container host is running inside of a Hyper-V virtual machine, MAC spoofing must be enable. This allows each container to receive an IP Address. To enable MAC address spoofing, run the following command on the Hyper-V host. The VMName property will be the name of the container host.

PS C:\> Get-VMNetworkAdapter -VMName <contianer host vm> | Set-VMNetworkAdapter -MacAddressSpoofing On

Install OS Images

An OS image is used as the base to any Windows Server or Hyper-V container. The image is used to deploy a container, which can then be modified, and captured into a new container image. OS images have been created with both Windows Server Core and Nano Server as the underlying operating system.

Container OS images can be found and installed using the ContainerProvider PowerShell module. Before using this module, it needs to be installed. The following commands can be used to install the module.

PS C:\> Install-PackageProvider ContainerProvider -Force

Return a list of images from PowerShell OneGet package manager:

PS C:\> Find-ContainerImage

Name                 Version                 Description
----                 -------                 -----------
NanoServer           10.0.10586.0            Container OS Image of Windows Server 2016 Techn...
WindowsServerCore    10.0.10586.0            Container OS Image of Windows Server 2016 Techn...

To download and install the Nano Server base OS image, run the following.

PS C:\> Install-ContainerImage -Name NanoServer -Version 10.0.10586.0
Downloaded in 0 hours, 0 minutes, 10 seconds.

Likewise, this command downloads and installs the Windows Server Core base OS image.

Issue: Save-ContainerImage and Install-ContainerImage cmdlets fail to work with a WindowsServerCore container image, from a remote PowerShell session.
Workaround: Logon to the machine using Remote Desktop and use Save-ContainerImage cmdlet directly.

PS C:\> Install-ContainerImage -Name WindowsServerCore -Version 10.0.10586.0
Downloaded in 0 hours, 2 minutes, 28 seconds.

Verify that the images have been installed using the Get-ContainerImage command.

PS C:\> Get-ContainerImage

Name              Publisher    Version      IsOSImage
----              ---------    -------      ---------
NanoServer        CN=Microsoft 10.0.10586.0 True
WindowsServerCore CN=Microsoft 10.0.10586.0 True

  • Windows Defender Overview for Windows Server Technical Preview. Windows Server Antimalware is installed and enabled by default in Windows Server 2016 Technical Preview, but the user interface for Windows Server Antimalware is not installed. However, Windows Server Antimalware will update antimalware definitions and protect the computer without the user interface. If you need the user interface for Windows Server Antimalware, you can install it after the operating system installation by using the Add Roles and Features Wizard.
  • What’s New in Remote Desktop Services in Windows Server 2016. For the Windows Server 2016 Technical Preview, the Remote Desktop Services team focused on improvements based on customer requests. We added support for OpenGL and OpenCL applications, and added MultiPoint Services as a new role in Windows Server.
  • What’s New in File and Storage Services in Windows Server 2016 Technical Preview. This topic explains the new and changed functionality of Storage Services. An update in storage quality of service now enables you to create storage QoS policies on a Scale-Out File Server and assign them to one or more virtual disks on Hyper-V virtual machines. Storage Replica is a new feature that enables synchronous replication between servers for disaster recovery, as well as stretching of a failover cluster for high availability..
  • What’s New in Web Application Proxy in Windows Server Technical Preview. The latest version of Web Application Proxy focuses on new features that enable publishing and preauthentication for more applications and improved user experience. Check out the full list of new features that includes preauthentication for rich client apps such as Exchange ActiveSync and wildcard domains for easier publishing of SharePoint apps.
  • What’s new in the Windows console. The underlying console host (Conhost.exe) has been updated in several ways, adding new and different functionality to the Windows command prompt, the Windows PowerShell prompt, and any other character-mode applications. For details, see What’s New in the Windows Console in Windows Server 2016 Technical Preview and Console Improvements in the Windows 10 Technical Preview , but you should take note of these important changes:
    • The new console functionality is enabled by default. If an existing application doesn’t work properly with the new console, you can select Use legacy console on the Options tab and then restart your application. You can also control individual aspects of the new functionality with registry keys; see details at the linked topics.
    • Console windows can be resized dynamically with the mouse. This could cause issues with some console applications.
    • Quick Edit mode is enabled by default. If this conflicts with your application, you can disable it on the Options tab.
    • There are new keyboard shortcuts for copy, paste, and history navigation. If these conflict with your application, you can disable them on the Options tab (look for Enable CTRL key shortcuts and Extended test selection keys).
    • The default font type for new console windows is TrueType. You can still use raster fonts, but they won’t scale properly on some displays.
    • Text wraps and reflows by default when you resize a window. If necessary, you can disable this on the Layouts tab.
    • In some cases, after upgrade installation, fonts in the console window might be very small. To adjust this, use the Fonts tab.
  • What’s New in Windows PowerShell 5.0. Windows PowerShell 5.0 includes significant new features—including support for developing with classes, and new security features—that extend its use, improve its usability, and allow you to control and manage Windows-based environments more easily and comprehensively. Multiple new features in Windows PowerShell Desired State Configuration (DSC) are also described in this topic.
  • What’s New in Networking in Windows Server Technical Preview. The majority of what you’ll find for networking is new in TP3. We bring a scalable network controller for programming policies, an L4 load balancer for high availability and performance, enhanced gateways for hybrid connectivity, and an underlying network fabric that converges RDMA traffic together with tenant traffic, DNS policies that control how your DNS servers respond to incoming requests, and better integration of DNS and IPAM.
