Defining Azure Resources with ARM Templates
Learn how to define and configure Azure resources using the resources section in ARM templates, where you can specify the name, type, API version, and other properties. ARM templates provide a powerful way to manage your infrastructure as code in Azure, allowing you to define and deploy resources with ease.
When working with ARM templates, the resources section plays a crucial role in detailing the exact configuration of the resources you need in your Azure environment. This section allows you to define the Azure resources you want to deploy, specifying their name, type, API version, and other properties.
To create a resource in an ARM template, you start by specifying the resource type, such as ‘Microsoft.Storage/storageAccounts’ for a storage account. You can then provide a unique name for the resource, along with any required properties. For example:
| Resource Type | Name | API Version | Properties |
|---|---|---|---|
| Microsoft.Storage/storageAccounts | myStorageAccount | 2022-12-01 | { ”accountType”: “Standard_LRS” } |
In the example above, we define a storage account resource of type ‘Microsoft.Storage/storageAccounts’ with the name ‘myStorageAccount’. We also specify the API version to use and provide additional properties, in this case, setting the account type to ‘Standard_LRS’.
By using the resources section in ARM templates, you can accurately define and configure your Azure resources, bringing consistency and reliability to your infrastructure management process.
