Windows Blueprints

Brooklyn can deploy to Windows servers using WinRM to run commands. These deployments can be expressed in pure YAML, and utilise PowerShell to install and manage the software process. This approach is similar to the use of SSH for UNIX-like servers.

About WinRM

WinRM - or Windows Remote Management to give its full title - is a system administration service provided in all recent Windows Server operating systems. It allows remote access to system information (provided via WMI) and the ability to execute commands. For more information refer to Microsoft's MSDN article on Windows Remote Management.aspx).

WinRM is available by default in Windows Server, but is not enabled by default. Brooklyn will, in most cases, be able to switch on WinRM support, but this is dependent on your cloud provider supporting a user metadata service with script execution (see below).

Locations for Windows

You must define a new location in Brooklyn for Windows deployments. Windows deployments require a different VM image ID to Linux, as well as some other special configuration, so you must have separate Brooklyn locations for Windows and Linux deployments.

In particular, you will most likely want to set these properties on your location:

  • imageId or imageNameRegex - select your preferred Windows Server image from your cloud provider.
  • hardwareId or minRam/minCores - since Windows machines generally require more powerful servers, ensure you get a machine with the required specification.
  • useJcloudsSshInit - this must be set to false. Without this setting, jclouds will attempt to connect to the new VMs using SSH, which will fail on Windows Server.
  • templateOptions - you may also wish to request a larger disk size. This setting is cloud specific; on AWS, you can request a 100GB disk by setting this property to {mapNewVolumeToDeviceName: ["/dev/sda1", 100, true]}.

In your YAML blueprint:

location:
  jclouds:aws-ec2:
    region: us-west-2
    identity: AKA_YOUR_ACCESS_KEY_ID
    credential: <access-key-hex-digits>
    imageNameRegex: Windows_Server-2012-R2_RTM-English-64Bit-Base-.*
    imageOwner: 801119661308
    hardwareId: m3.medium
    useJcloudsSshInit: false
    templateOptions: {mapNewVolumeToDeviceName: ["/dev/sda1", 100, true]}

Or for an existing Windows machine:

location:
  byon:
    hosts:
    - winrm: 10.0.0.1
      user: Administrator
      password: pa55w0rd
      osFamily: windows

A Sample Blueprint

Creating a Windows VM is done using the org.apache.brooklyn.entity.software.base.VanillaWindowsProcess entity type. This is very similar to VanillaSoftwareProcess, but adapted to work for Windows and WinRM instead of Linux. We suggest you read the documentation for VanillaSoftwareProcess to find out what you can do with this entity.

Entity authors are strongly encouraged to write Windows PowerShell or Batch scripts as separate files, to configure these to be uploaded, and then to configure the appropriate command as a single line that executes given script.

For example here is a simplified blueprint:

name: Server with 7-Zip

location: windows-machine       # register this, or inject the above instead

services:
- type: org.apache.brooklyn.entity.software.base.VanillaWindowsProcess
  brooklyn.config:
    templates.preinstall:
      /path/to/install7zip.ps1: "C:\\install7zip.ps1"
    install.command: powershell -command "C:\\install7zip.ps1"
    customize.command: echo true
    launch.command: echo true
    stop.command: echo true
    checkRunning.command: echo true
    installer.download.url: http://www.7-zip.org/a/7z938-x64.msi

The installation script - referred to as /path/to/install7zip.ps1 in the example above (but put this on your Brooklyn server or in the bundle classpath) - is:

$Path = "C:\InstallTemp"
New-Item -ItemType Directory -Force -Path $Path

$Url = "${config['installer.download.url']}"
$Dl = [System.IO.Path]::Combine($Path, "installer.msi")
$WebClient = New-Object System.Net.WebClient
$WebClient.DownloadFile( $Url, $Dl )

Start-Process "msiexec" -ArgumentList '/qn','/i',$Dl -RedirectStandardOutput ( [System.IO.Path]::Combine($Path, "stdout.txt") ) -RedirectStandardError ( [System.IO.Path]::Combine($Path, "stderr.txt") ) -Wait

This is only a very simple example. A more complex example can be found in the Microsoft SQL Server blueprint in the Brooklyn source code.
