If you missed our following articles on Exam : Developing Microsoft Azure Solutions, Please have a look once here :
In our last blog, we have discussed about Azure Resource Manager (ARM). As We know that, Azure Resource Manager allow us to generate and use a template to deploy, update, or delete all the resources for a solution in a single operation and the template is know as ARM Template. Today we will see, how to create and deploy a ARM template using Azure Portal. Let’s proceed step by step and see how it works.
- Connect to your Azure portal dashboard using your subscription account. If you don’t have an Azure subscription, create a free account before you begin. Then you can connect to the azure portal dashboard as in following figure.

- For a better understanding, we have created two different resource groups. “ManasARMTemplatesGroup” will be used as source resource group and the other one “ManasARMDestnation” will be used as destination resource group, where we will deploy our template, as shown in the following figure.
Figure 2: Azure Certification 70-532 – Two Resource Group created
Figure 3: Azure Certification 70-532 – Destination Resource Group where template will be deployed
- Before generating the ARM template, let’s create couple of resource in the source resource group. So that when we will generate the template, it will have couple of resources in the template. Here we have created one storage account and one Virtual Machine. Virtual Machine creation, in turn it created few more dependent resources, as in following figure.

- Verify all resources, we required in the our template before download the template. To download the resource group template, go to the source resource group (ManasARMTemplatesGroup ) and from resource group page, Click on “Automation script” under “Setting” and click on Download button to download the template, as in following figure.

- After downloading the template as a package, Open template.json file and edit as per the requirement like change the VM name and Storage Account name and save the file. Azure requires that each Azure service has a unique name. The deployment fails if we enter a storage account name that already exists. To avoid this issue, we can also use a template function call uniquestring() to generate a unique storage account name. Here I have set the name with hard coded value, as shown in following figure.

- Once we are ready with our template file, the next step is to deploy the template to create all resources defined in the template. To start with deployment follow the below steps.
- In the Azure portal, select Create a resource.
- In Search the Marketplace, type template deployment, and then press ENTER.
- Select Template deployment as in following figure
Figure 7: Azure Certification 70-532 – Select Template Deployment service
- Select Create and then Select Build your own template in the editor.
- Select Load file, and then follow the instructions to load template.json we downloaded in the last section.
- After successfully load the template file and click Save button, in turn it open one form with all parameters we have specified in our template and asking to purchase the order. To start deploy, we must Click Purchase button, as shown in the following figure.

- If everything went well and deployment will be success otherwise it will fail with error. In our case we have faced following three errors. So I have written following articles for the fixes of the following issues.
- After fixing the above issues, we ware able to successfully deploy as shown in the following figure
Figure 9: Azure Certification 70-532 – successfully deployedTo verify, whether we got success with our deployment, lets move to destination resource group and see if all resources created or not as shown in the following figure.
