Lab 03b - Manage Azure resources by Using ARM Templates

Student lab manual

Lab scenario

Now that you explored the basic Azure administration capabilities associated with provisioning resources and organizing them based on resource groups by using the Azure portal, you need to carry out the equivalent task by using Azure Resource Manager templates.

Objectives

In this lab, you will:

Task 1: Review an ARM template for deployment of an Azure managed disk
Task 2: Create an Azure managed disk by using an ARM template
Task 3: Review the ARM template-based deployment of the managed disk

Estimated timing: 20 minutes

Exercise 1

Task 1: Review an ARM template for deployment of an Azure managed disk

In this task, you will create an Azure disk resource by using an Azure Resource Manager template.

Sign in to the Azure portal.
In the Azure portal, search for and select Resource groups.
In the list of resource groups, click az104-03a-rg1.
On the az104-03a-rg1 resource group blade, in the Settings section, click Deployments.
On the az104-03a-rg1 - Deployments blade, click the first entry in the list of deployments.
On the Microsoft.ManagedDisk-XXXXXXXXX | Overview blade, click Template.

Note: Review the content of the template and note that you have the option to Download it to the local computer, Add to library, or Deploy it again.
Click Download and save the compressed file containing the template and parameters files to the Downloads folder on your lab computer.
On the Microsoft.ManagedDisk-XXXXXXXXX | Template blade, click Inputs.
Note the value of the location parameter. You will need it in the next task.
Extract the content of the downloaded file into the Downloads folder on your lab computer.

Note: These files are also available as \Allfiles\Labs\03\az104-03b-md-template.json and \Allfiles\Labs\03\az104-03b-md-parameters.json
Close all File Explorer windows.

Task 2: Create an Azure managed disk by using an ARM template

In the Azure portal, search for and select Deploy a custom template.
On the Custom deployment blade, click Build your own template in the editor.
On the Edit template blade, click Load file and upload the template.json file you downloaded in the previous task.
Within the editor pane, remove the following lines:
```
"sourceResourceId": {
    "type": "String"
},
"sourceUri": {
    "type": "String"
},
"osType": {
    "type": "String"
},
```
```
"hyperVGeneration": {
    "defaultValue": "V1",
    "type": "String"
},      
```
```
"osType": "[parameters('osType')]",
```
Note: These parameters are removed since they are not applicable to the current deployment. In particular, sourceResourceId, sourceUri, osType, and hyperVGeneration parameters are applicable to creating an Azure disk from an existing VHD file.
Save the changes.
Back on the Custom deployment blade, click Edit parameters.
On the Edit parameters blade, click Load file and upload the parameters.json file you downloaded in the previous task, and Save the changes.

Back on the Custom deployment blade, specify the following settings:

Setting	Value
Subscription	the name of the Azure subscription you are using in this lab
Resource Group	the name of a new resource group az104-03b-rg1
Region	the name of any Azure region available in the subscription you are using in this lab
Disk Name	az104-03b-disk1
Location	the value of the location parameter you noted in the previous task
Sku	Standard_LRS
Disk Size Gb	32
Create Option	empty
Disk Encryption Set Type	EncryptionAtRestWithPlatformKey
Network Access Policy	AllowAll

Select Review + Create and then select Create.
Verify that the deployment completed successfully.

Task 3: Review the ARM template-based deployment of the managed disk

In the Azure portal, search for and select Resource groups.
In the list of resource groups, click az104-03b-rg1.
On the az104-03b-rg1 resource group blade, in the Settings section, click Deployments.
From the az104-03b-rg1 - Deployments blade, click the first entry in the list of deployments and review the content of the Input and Template blades.

Clean up resources

Note: Do not delete resources you deployed in this lab. You will reference them in the next lab of this module.

Review Questions

Can you mark parameters as optional and mandatory in a template?
What happens if you do not add a mandatory parameter like “User Name” for Virtual Machines in the template?

Review
