Want to become a maintainer of PowervRA or PowervRO?

When Craig and I first created PowervRA and PowervRO in 2016 we only initially thought about using them for our own purposes, since we were on a project at the time which required heavy use of automation around vRA and vRO. When we decided to put them out into the community we never expected them to become as popular as they have done. It was a fun experience for us, both in learning about collaborating, developing and releasing a PowerShell module, and the benefits it was bringing to our own jobs.

PowervRO – Now available on macOS and Linux via PowerShell Core!

Back Story Back in January 2017 Craig and I made PowervRA available for macOS and Linux via PowerShell Core. It was always our intention to do the same thing for PowervRO and , although slightly later than we hoped, we’re finally able to do that. PowerShell Core has come a long way itself over the last year, currently in Release Candidate and soon to be GA, and I’m sure a lot of the hard work and community feedback which has gone into that has helped make the job of PowervRO supporting PowerShell Core very straightforward.

Using Pester and PowervRO as a Unit Test Framework for vRO

vRealize Orchestrator doesn’t have an in-built Unit Test Framework, however I realised that it might be possible to use a combination of Pester and PowervRO for now to achieve similar results. Let’s take a look at an example using a very simple workflow, Workflow1. Workflow1 has two inputs, a and b, both numbers: Workflow1 has a single scriptable task that takes the inputs a and b, multiples them together and stores the result in c, which is output from the workflow.

Exporting and Importing vRO Packages with PowervRO

One thing that I know colleagues and others are keen to automate with PowerShell and vRO is exporting and importing vRO packages. If you’re not familiar with a vRO package it is typically used to bundle up all of the Workflows / Actions / Configuration Elements / Resource Elements which make up the code for a particular project and use the package to transport the code to another system. So you may for instance wish to export a package and copy it to another vRO server or maybe into a version control system, or you may wish to automate the deployment of vRO itself and include importing the code as a final step.

Export vRO Workflow Schema Images with PowervRO

Aside from any documentation around your vRO workflows, one of the best ways to quickly get up-to-speed with what it does and visualise how it is put together is to look at the schema. Wouldn’t it be handy if you could easily get hold of an image of the schema for one or multiple workflows? Well with PowervRO and your PowerShell console you can! The REST API supports this, so we have included a function Export-vROWorkflowSchema .

Exporting and Importing vRO Workflows with PowervRO

There are a number of different ways to get your developed vRO content from one system to another: exporting / importing single items, exporting / importing vRO Packages containing multiple items, synchronising content directly between vRO systems. In this example I’ll show you how to use PowervRO to export and import workflows from and to vRO. Export vRO Workflows To export a single workflow is pretty straightforward with the function Export-vROWorkflow:

Obtaining vRO Workflow State and Result with PowervRO

In the previous episode we looked at how to invoke a vRO workflow with PowerShell, via PowervRO and the Invoke-vROWorkflow function. Once you have kicked the workflow off you are likely to then want to find out the state of the workflow, when it has finished and any output from the workflow. Here’s how to do this via PowervRO. Check the Workflow State: First of all, we need to identify which execution of a particular workflow we want to check the state of.

Automate vRealize Orchestrator with PowerShell: Introducing PowervRO

For the PowerCLI book 2nd Edition I helped put together a chapter on vRealize Orchestrator. Most of the chapter was focused on running PowerShell scripts from vRO, which was something I’d had a fair bit of experience with in projects I had been on and also thought would be what most people reading would be interested in. At the end of the chapter I added a few functions using the vRO REST API to run things in vRO from PowerShell as a bit of an after-thought.
