How To Make vRO Execute Python Code Blocks

vRealize Orchestrator (vRO) is a powerful automation platform that enables you to automate and orchestrate various IT processes, including the execution of Python scripts. In this article, we will show you how to set up vRO to run Python scripts and provide some tips along the way.


Before you can run Python scripts in vRO, you need to have the following:

  • A working installation of vRealize Orchestrator (8.10.2+).
  • A vCloud Suite Advanced or Enterprise license. You cannot run Python scripts with the standard vCenter license for vRO

Setting up vRO to run Python scripts

To set up vRO to run Python scripts, follow these steps:

  • Open the vRealize Orchestrator client and log in with your administrator credentials. (https://<servername>/orchestration-ui)
  • In the main menu, go to the “Assets” and select “Environments” from the submenu.
  • Click the “New Environment” button to create a python3.7 environment.
  • In the “General” tab, enter a name and a description for the environment.

Assigning vCenter tags using vRealize Orchestrator

Today I needed to assign some vCenter tags to some VMs I was deploying using vRealize Automation.

The scenario was that the customer did not want backup of VMs deployed by the vRA test environment, and in production they wanted a specific backup tier.

They are using Veeam backup, so the vRA test environment needed to have a NoBackup Tag, and production needed some other tag, depending on the type of server being deployed.

vRO does not provide very extensive support for these operations out of the box, but vRO 7.2 does come with some sample workflows.

To get started with vCenter tagging you need to configure a vAPI endpoint and a vAPI metamodel.
