How to Add a Linux Machine as PowerShell Host in vRO

By Spas Kaloferov

Introduction

In this article we will look into the alpha version of Microsoft Windows PowerShell v6 for both Linux and Microsoft Windows. We will show how to execute PowerShell commands between Linux , Windows, and VMware vRealize Orchestrator (vRO):

  • Linux to Windows
  • Windows to Linux
  • Linux to Linux
  • vRO to Linux

We will also show how to add a Linux PowerShell (PSHost) in vRO.

Currently, the alpha version of PowerShell v6 does not support the PSCredential object, so we cannot use the Invoke-Command command to programmatically pass credentials and execute commands from vRO, through a Linux PSHost, to other Linux machines, or Windows machines. Conversely, we cannot execute from vRO –> through a Windows PSHost –> to Linux Machines.

To see how we used the Invoke-Command method to do this, see my blog Using CredSSP with the vCO PowerShell Plugin (SKKB1002).

In addition to not supporting the PSCredential object, the alpha version doesn’t support WinRM. WinRM is Microsoft’s implementation of the WS-Management protocol, a standard Simple Object Access Protocol (SOAP)-based, firewall-friendly protocol that enables hardware and operating systems from different vendors to interoperate. Therefore, when adding a Linux machine as a PowerShell host in vRO, we will be using SSH instead of WinRM as the protocol of choice.

The PowerShell v6 RTM version is expected to support WinRM, so we will be able to add the Linux PSHost with WinRM, and not SSH.

So, let’s get started.
