Add tags in your ARM template

 

Prerequisites

We recommend that you complete the tutorial about Quickstart Templates, but it's not required.

You need to have Visual Studio Code with the Resource Manager Tools extension and either Azure PowerShell or Azure Command-Line Interface (CLI). For more information, see template tools.

Review template

Your previous template deployed a storage account, an App Service plan, and a web app.

After you deploy these resources, you might need to track costs and find resources that belong to a category. You can add tags to help solve these issues.

Add tags

You tag resources to add values that help you identify their use. You can add tags that list the environment and the project. You can also add them to identify a cost center or the team that owns the resource. Add any values that make sense for your organization.

The following example highlights the changes to the template. Copy the whole file and replace your template with its contents.

Deploy template

It's time to deploy the template and look at the results.

If you haven't created the resource group, see Create resource group. The example assumes you've set the templateFile variable to the path to the template file, as shown in the first tutorial.

Azure PowerShell
New-AzResourceGroupDeployment `
  -Name addtags `
  -ResourceGroupName myResourceGroup `
  -TemplateFile $templateFile `
  -storagePrefix "store" `
  -storageSKU Standard_LRS `
  -webAppName demoapp

 Note

If the deployment fails, use the verbose switch to get information about the resources you're creating. Use the debug switch to get more information for debugging.

Verify deployment

You can verify the deployment by exploring the resource group from the Azure portal.

  1. Sign in to the Azure portal.

  2. From the left menu, select Resource groups.

  3. Select the resource group you deployed to.

  4. Select one of the resources, such as the storage account resource. You see that it now has tags.

    Screenshot of Azure portal showing tags on a storage account resource.

Clean up resources

If you're moving on to the next tutorial, you don't need to delete the resource group.

If you're stopping now, you might want to delete the resource group.

  1. From the Azure portal, select Resource groups from the left menu.
  2. Type the resource group name in the Filter for any field... text field.
  3. Check the box next to myResourceGroup and select myResourceGroup or your resource group name.
  4. Select Delete resource group from the top menu.

Terraform

Image
  Terraform is an infrastructure as code tool that lets you build, change, and version cloud and on-prem resources safely and efficiently. HashiCorp Terraform is an infrastructure as code tool that lets you define both cloud and on-prem resources in human-readable configuration files that you can version, reuse, and share. You can then use a consistent workflow to provision and manage all of your infrastructure throughout its lifecycle. Terraform can manage low-level components like compute, storage, and networking resources, as well as high-level components like DNS entries and SaaS features. How does Terraform work? Terraform creates and manages resources on cloud platforms and other services through their application programming interfaces (APIs). Providers enable Terraform to work with virtually any platform or service with an accessible API. HashiCorp and the Terraform community have already written  thousands of providers  to manage many different types of resources and services.

Understanding the MoSCoW prioritization | How to implement it into your project Projects, irrespective of their size or complexity, often juggle numerous tasks and requirements. In such a scenario,  MoSCoW prioritization  becomes essential to ensure the successful completion of the project.  Besides, it is also a very effective way to manage project priorities. With a straightforward and adaptable approach, the MoSCoW method helps manage stakeholder expectations and improve project outcomes. What is the MoSCoW prioritization technique?  The MoSCoW method is a prioritization matrix widely used in project management and software development. The term MoSCoW is an acronym that stands for  Must have ,  Should have ,  Could have , and  Won’t have , each denoting a level of priority. Here is the breakdown of the MoSCoW method:  Must have:  These are critical requirements that the project cannot be completed without them. If these are not fulfilled, the project is con

Kubernetes

  Using containers to host applications and other processes has gone mainstream. As more and more workload is moved into containers, management systems are needed to handle the demands of containerized applications at scale. One of the most popular options for managing  container-based workload is Kubernetes . Kubernetes combines container management automation with an extensible API to create a cloud-native application management powerhouse. At its core, Kubernetes manages the placement of pods, which can consist of one or more containers, on a Kubernetes cluster node. Additionally, if one of these pods crashes, Kubernetes can create a new instance of it. If a cluster node is removed, Kubernetes can move any affected workload to a different node in the cluster. On top of that, Kubernetes pods can be scaled to provide more or less throughput to meet scale demands and these scale operations can be triggered manually or automatically using Kuberentes horizontal pod auto-scaling. Finally,
