Azure Resource Manager Templates Quick Start Guide

By: Ritesh Modi

Overview of this book

Azure Resource Manager (ARM) templates are declarations of Azure resources in the JSON format to provision and maintain them using infrastructure as code. This book gives practical solutions and examples for provisioning and managing various Azure services using ARM templates. The book starts with an understanding of infrastructure as code, a refresher on JSON, and then moves on to explain the fundamental concepts of ARM templates. Important concepts like iteration, conditional evaluation, security, usage of expressions, and functions will be covered in detail. You will use linked and nested templates to create modular ARM templates. You will see how to create multiple instances of the same resources, how to nest and link templates, and how to establish dependencies between them. You will also learn about implementing design patterns, secure template design, the unit testing of ARM templates, and adopting best practices. By the end of this book, you will understand the entire life cycle of ARM templates and their testing, and be able to author them for complex deployments.

Output Resource Properties and Configuration

It is a good practice to output results from ARM templates using the Outputs section. Outputs are important because they provide additional feedback to the deployer in terms of a resource's status and its configuration. This output configuration information can then further be used for sending the same template to other resources, or it can be used in other templates. These outputs can also be used to unit test the resource configuration using Pester.

An example of an ARM template generating outputs and returning values is shown next. Here, two values are returned—one of them is of the type string and returns the FQDN of the created Azure SQL Server, and the other is of the type object, returning the complete Azure Server configuration:

"outputs": {
"SQLServer1": {
"type": "string...
