Summary

  • 3 minutes

In this module, you created an Azure CLI script to automate the creation of multiple VMs. Despite its relative simplicity, the script showcases the powerful potential ofAzure CLI when combining loops and variables with Azure CLI reference commands.

Azure CLI is an excellent choice for automating the administration and management of Azure resources. Its clean syntax and powerful scripting capabilities make it a valuable tool, even for administrators new to Bash. By automating time-consuming and error-prone tasks, you can reduce administrative overhead and improve overall efficiency and quality.

Clean up

The sandbox automatically cleans up your resources when you're finished with this module.

When you're working in your own subscription, it's a good idea at the end of a project to identify whether you still need the resources you created. Resources that you leave running can cost you money. You can delete resources individually or delete the resource group to delete the entire set of resources.

Delete a resource group

Caution

The following examples delete resource groups and all resources contained within it. If resources outside the scope of this training module exist in the specified resource group, they're also deleted.

Use the az group delete command to delete a single resource group and all related resources.

az group delete --name myResourceGroupName

When prompted to confirm the deletion, answer Y and Enter, or add the --yes parameter to skip the prompt. The command might take several minutes to complete.

Delete resource groups using a script

Deleting one resource group at a time when testing can be tedious. If you used a naming convention in your testing process, consider using a script. This example deletes all resource groups whose name begins with msdocs.

#!/bin/bash
# Set your subscription if you haven't already
subscriptionID=00000000-0000-0000-0000-00000000
az account set --subscription $subscriptionID

# Get the name of all resource groups that start with 'msdocs'
az group list --query "[?starts_with(name, 'msdocs') == \`true\`].name" -o table

# Delete resource groups without a confirmation prompt (--yes)
# Do not wait for the operation to finish (--no-wait)
for rgList in $(az group list --query "[?starts_with(name, 'msdocs') == \`true\`].name" -o tsv); 
do
    echo "deleting resource group $rgList"
    az group delete --name $rgList --yes --no-wait
done

# get the status of all resource groups in the subscription
az group list --output table

Check your knowledge

1.

True or false: The Azure portal, Azure PowerShell, and Azure CLI offer significantly different services, making it unlikely that all three support the operation you need.

2.

Suppose you're building a video-editing application that offers online storage for user-generated video content. You plan to store the videos in Azure Blobs, so you must create an Azure storage account. Once the storage account is in place, you would unlikely remove and recreate it because all the user videos would be deleted. Which tool is likely to offer the quickest and easiest way to create the storage account?
