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.

Group related parameters

Again, it is a general tendency to declare many parameters for a resource configuration, and these parameters are put randomly within the parameters section. Ideally, the parameters for a resource configuration should be grouped together as a single parameter and sent to the ARM template.

In this example, an ARM template accepts a single SQL Server resource configuration parameter of the object data type:

    "sqlServerProperties": {
"type": "object"
},

And the parameters file provides all the parameters to it as a single object, as shown next:

   "sqlServerProperties": {
"value": {
"administratorLogin": "eCommerceAdmin",
"databaseName": "eCommerceDatabase",
"collation": "SQL_Latin1_General_CP1_CI_AS",
...
