Complex Azure Template Odyssey Part One: The Environment

Part Two | Part Three | Part Four

Over the past month or two I’ve been creating an Azure Resource Template to deploy and environment which, previously, we’d created old-style PowerShell scripts to deploy. In theory, the Resource Template approach would make the deployment quicker, easier to trigger from tooling like Release Manager and make the code easier to read.

The aim is to deploy a number of servers that will host an application we are developing. This will allow us to easily provision test or demo environments into Azure making as much use of automation as possible. The application itself has a set of system requirements that means I have a good number of tasks to work through:

This post is accurate at time of writing and will show you how to deploy PowerShell scripts and resources to an Azure Virtual Machine through a Resource Template.

The code snippet below shows a customScriptExtension pulled from one of my templates.
