Get-OvfConfiguration on steroids

Generate a PowerCli function from ANY OVF/OVA package to ease the creation of an ovfconfiguration object to be used with Import-VApp.


The audience for this script is anyone interested to deploy a VMware appliance via PowerCLI.
This script is based on Get-OvfConfiguration and will generate, for any ovf/ova package, a PowerCli friendly function designed to create an OvfConfiguration specifically for this package.

The Get-OvfConfiguration is the foundation for everything mentioned in this post so please be sure to be familiar with it before reading further.
There is an excellent introduction for this topic in this post written by Brian Graf.
PowerCLI 5.8 New Feature: Get-OvfConfiguration (Part 1 of 2)

Function generated for “VMware-vRealize-Log-Insight-2.5.0-2347850.ova”
Let’s start by showing what kind of function can be generated and then more details will be provided regarding how it has been done.

function New-OvfConfiguration_VMware-vRealize-Log-Insight-2.5.0-2347850{
<#
.SYNOPSIS
This PowerCLI cmdlet create a PowerCli object OvfConfiguration specifically designed to be used when importing the VMware-vRealize-Log-Insight-2.5.0-2347850 ovf/ova package with the Import-VApp cmdlet.
It relies on the get-ovfconfiguration PowerCli cmdlet

.DESCRIPTION
This function is based on the original get-ovfconfiguration PowerCLI cmdlet...
...and convert it in a Powershell friendly function specifically for the package VMware-vRealize-Log-Insight-2.5.0-2347850
It is mandatory to be connected to one vCenter or Get-OvfConfiguration will throw an error

All information in the ovf or ova package available via get-OvfConfiguration have been “converted” in a PowerShell way.

For example with “VMware-vRealize-Log-Insight-2.5.0-2347850.ova” and the parameter DeploymentOption:
The OvfTypeDescription is: string[“xsmall”, “small”, “medium”, “large”]
The default value is “small”
This will become in the parameter section of the function generated:
param(
[ValidateSet(“xsmall”, “small”, “medium”, “large”)]
$DeploymentOption = “small”,

Maybe you are not interested to deploy an Orchestrator appliance…
So in that case what about generating a function for ANY ovf / ova files?

The script to generate script
Prerequisite:
PowerCLI 5.8 or above
Connection established with one vcenter server

Step 1: Add the function Export-OvfConfigurationSettings
This is a recursive function that uses as a parameter an ovfconfiguration object. It extracts all properties available through Get-OvfConfiguration for every user configurable parameters and return a PSObjectTable.

function Export-OvfConfigurationSettings{
	param(
	$ToAnalyse,
	$PackageName,
	$PropertyPath
	)
	
	Process{	
		If($ToAnalyse | Get-Member -MemberType Property | where {$_.Name -ne "Source"}){

		
					$FinalTable = New-Object -Type PSObject -Prop ([ordered]@{
					"Package" = $PackageName;
					"PropertyPath" = ($PropertyPath.substring(1));
					"DefaultValue" = $ToAnalyse.DefaultValue;
					"Description" = $ToAnalyse.Description ;
					"Key" = $ToAnalyse.Key;
					"OvfTypeDescription" = $ToAnalyse.OvfTypeDescription;
					"Value" = $ToAnalyse.Value;
					})
					Return $FinalTable
		
		
		}
		
		$AllCodeProperty = $ToAnalyse | Get-Member -MemberType CodeProperty
		ForEach($CodeProperty in $AllCodeProperty){
		$CodePropertyName = $CodeProperty.Name
		$PropertyPathForThisCodeProperty = $PropertyPath + "."+ $CodePropertyName
		Export-OvfConfigurationSettings -ToAnalyse $ToAnalyse.$CodePropertyName -PackageName $PackageName -PropertyPath $PropertyPathForThisCodeProperty
		}
		
	}
}

Step 2: Generate the function
I apologize in advance the script is not really “clean”… goal was to have a working script and then improve it based on feedback if any.
Comments are in the code.

Notes:
[System.IO.StreamWriter] has been used to write faster the output file according to this post.
powershell-and-writing-files-how-fast-can-you-write-to-a-file

The function generated should help you to understand faster what is the role of each parameters and will prevent you in some case to enter wrong values.
This is the case with validateset for example, a typo mistake will be identified even before trying to import the vapp.
This will be however only as good as the ovf definition.

Finally I strongly recommend the following links that are closely related to this topic.

FAQ:
Why using long parameter name like “vami_VMware_vRealize_Orchestrator_Appliance_ip0” instead of “ip0”?

Unfortunately for some package the last part is not unique. This is the case with “vCenter-hyperic-5.8.4-EE”
$OvfConfiguration.vami.vCenter_Hyperic_Server.ip0.Value
$OvfConfiguration.vami.vFabric_vPostgres_DB.ip0.Value
It should be possible to check for duplicate and only use the full name when needed however I am not really sure if it is worth the extra work.
Especially when the full parameter name helps to identify its purpose.

I have some suggestions.
Good news. I am still in a learning process, so any good advice will be welcomed for the future updates of this script, which will then be available for everyone.

Bonus: Generate an ovfconfiguration for vCenter Appliance 6
Mount the VMware-VCSA-all-6.0.0-2562643.iso
Copy the file “CD drive\vcsa\ vmware-vcsa” to a local folder.
This file is actually an ova package
Unzip the file and you will find the “VMware-vCenter-Server-Appliance-6.0.0.5100-2562625_OVF10.ovf”
You can then rename the file “vmware-vcsa” as “VMware-vCenter-Server-Appliance-6.0.0.5100-2562625_OVF10.ova”
You will find below the function generated for this package.
