Chapter 2.4 - Using ARM Templates

Exampling ARM Templates

• ARM Templates
  • Infrastructure as Code (IaC)
    • Codify our infrastructure, using this ARM template, we can pass it into the Azure Resource Manager for deployment, it will find the necessary providers.
  • Deploy environments quickly
    • It will quickly deploy our environments at various scopes, such as subscriptions or a resource group.
  • Repeatable deployments

Components of ARM Templates

ARM Template:

{
	"$schema": "https://schema.management.azure.com"
,
	"contentVersion":
"1.0.0.0",
	"parameters": {},
	"variables": {},
	"resources": {},
	"outputs": {}
}

• The parameters and variables components are used to pass information to the template.
• The resources component is used to define resources in the template.
• The outputs component is used to return output from the execution of the template.

Key Takeaways

• ARM Template
  • Declarative JSON (Infrastructure as Code)
    • Using parameters, variables, resources, outputs, etc in ARM templates allows us to create resources inside of Azure
  • Quickly deploy repeatable and modular environments
