PowerShell & vCO: Roadmap for next version of PowerSSHell-Plugin

In August I released the first technical preview of my PowerSSHell-Plugin for vCO, which allows you to run Powershell-Commands directly from within workflows.

For the next version (release date: soon  :mrgreen:) I plan following updates:

  • More Examples (Workflows & Actions) in the Package
  • Documentation (what’s this?)
  • Authentication via Public-Key

Support for Queueing Powershell-Commands to a certain server and maintaining a single connection (this fits to the updated Personal License for the necessary PowerShell Server)

For more information and the download óf the current version, visit

If you have some further ideas, feature requests or found some bugs, join the discussion on!

If you need to buy some powershell-inside licences, contact me for a discount voucher!


Welcome back, Perspectives! (or: How to provide webbased UI for vCO without programming?)

VMware Labs published the Perspectives Plugin for vCO. It allows you to provide a webinterface for users to start and monitor Workflows. It is quite flexible, you can define different “perspectives” (list of workflows) for different user groups. And the best: All of this can be done without programming any single line of HTML/JavaScript-Code (The setup itself is again done by Workflows).

To download the Perspectives Plugin:

The Documentation:

For a further description and configuration example:

To get an overview which Perspectives you already have created and which Workflows are provided in each, go to the Inventory-Tab of your vCO-(Smart-)Client to get a nice tree-view:

Be aware, that (as all Flings from VMware Labs) the Plugin is under Technical Preview License and therefore not supported.

For other alternatives to provide users a webbased interface to the Orchestrator, read this discussion…


ApiWiz has left the building…

In his Blog post “Moving on…” Steve Jin (@sjin2008), vSphere API Wizard, author of THE book about vSphere API, creator of the opensource vSphere Toolkit for Java, announced that he has left VMware to “explore new opportunities”.

Steve did a great job evangelizing the API, and published really cool stuff on his blog which helps people to get-started and to dig-deep into the API. His blog also contains a lot of good read besides the deep coding stuff, my personal favourites:

I will continue to recommend his book to everybody who wants to automate vSphere, regardless which toolkit or programming language you use (among other things because it’s the only public source for UML-charts of the vSphere API data model (@vSphere API-Documentation team: read this! :-P) ).

Steve, thank you very much for all the help and the nice chats! Good luck for the future, and enjoy your “new super fast desktop”!


Free self-paced online JavaScript Training

Preparing a “Getting Started Guide” for vCO I stumbled over a real pearl which cannot wait to be tested: provides a free, self-paced online training for JavaScript starters. It teaches you the basics of JavaScript, like Variables, if-clauses and loops, in small lectures.

If you create an account (optional), the system remember your progress.

So, if you’re new to JavaScript, Codecademy is a quick way to get started!
