I work on Azure Tenants that utilize multiple subscriptions in their design. I wanted to centralize my Azure Automation work and use a single Automation account. By default, I found that powershell scripts I fired off from Azure Automation work within the subscription that the Automation account was created within. But business requirements necessitate multiple subscriptions and MY requirements necessitate using a single Automation Account to simplify my life (and the lives of everyone else that I work with). A running joke is that, when it comes to IT, well-intention’d laziness is a virtue… We rebrand laziness as “simplicity,” “automation,” and/or “efficiency,” depending on the context of the conversation of course. I often say somewhat tongue-n-cheek that “you don’t want your IT department to be “busy” all the time.” An all-the-time overly busy IT department typically means that something was poorly planned and/or your network is being held together with spit and frayed ethernet cable. Anyhow, I digress…
With that groundwork laid, the goal is a Powershell automation script that can essentially “hop” subscriptions as needed. I also value modularity. Goodness knows that in the pursuit of laziness we should never do the same work twice except in the most extreme or dire circumstances. To that end, I wrote a simple function I could just drop into any script along with an additional parameter and now said script can be used across subscriptions…
