How to manage Azure resource groups with the Azure CLI
An Azure resource group is a container that holds related resources for an Azure solution. A resource group might contain storage, virtual machines, apps, dashboards, services, or almost anything you deal with in Azure.
The Azure Command-Line Interface (CLI) allows you to create, persist, and set default Azure resource groups. The CLI will also allow you to clean up resources after creating them.
Azure Region Identification
Azure customers can choose to deploy resources in many different regions. In some cases, customers may be able to reduce costs by selecting nearby regions offering the same services. If a nearby region is identified, a message will display the region to select for future deployments.
In the following example, the az config command is used to disable the region recommendation message:
az config set core.display_region_identified=no
For more information about Azure regions, see Choose the right Azure region for you.
Create a resource group
To create a resource group, use the az group create command:
az group create --name MyResourceGroup --location eastus
A resource group belongs to a single location. To see all the locations supported in your current subscription, run the az account list-locations command:
az account list-locations
To see all the resource groups for your current subscription, use the az group list command:
az group list --output table
Tip
The --output parameter is a global parameter, available for all commands. The table value presents output in a friendly format. For more information, see Output formats for Azure CLI commands.
When you create a resource, you create it in a resource group. The following example shows a storage account created by using the az storage account create command:
az storage account create --resource-group MyResourceGroup --name storage134 --location eastus --sku Standard_LRS
To remove a resource group, run the az group delete command:
az group delete --name MyResourceGroup
When you remove a resource group, you delete all the resources that belong to it. You can't undo this action. If you try any of the commands in this article, deleting the resource groups you create cleans up your account.
Set a default resource group
You can set a default resource group for all the commands that you run from your local Azure CLI or from Azure Cloud Shell. Azure CLI stores this configuration locally in a config file. To see your current configuration, run the az config get command:
az config get
The result shows default resource groups and other default values. If you're using Azure CLI for the first time, the results might be empty.
To set a default resource group for your Azure CLI installation, run the az config set command:
az config set defaults.group=MyResourceGroup
The command sets a value for a specified key, in this case defaults.group. For available configuration options, see Azure CLI configuration.
Note
The az config set command does not validate the existence of the resource group you enter. The command simply stores the key-value pair.
After you run the command, the following two commands would give you the same result:
az storage account create --resource-group MyResourceGroup --name storage01 --location eastus --sku Standard_LRS
az storage account create --name storage01 --location eastus --sku Standard_LRS
A resource group belongs to a subscription. If your organization has more than one subscription, you need to set that subscription before working with a resource group in the subscription. If the default value of a resource group doesn't belong to your current subscription, an error results. For more information about multiple subscriptions, see Use multiple Azure subscriptions.
You don't have to reset the default to use other resource groups. Instead, specify the resource group:
az group create --name OtherResourceGroup --location eastus
az storage account create --resource-group StorageGroups --name storage03 --location westus --sku Standard_LRS
The default value is for you only. It doesn't affect other users or changes you make through the Azure portal.
If you're using persisted parameter values, as described in this article, those values take precedence over defaults set in the config file.
Set a resource group lock
As an administrator, you may need to lock a resource group to prevent users from deleting or modifying it. For more information, see Lock resources to prevent unexpected changes.
In Azure CLI, use the az group lock commands. For instance, the az account lock create command can prevent users from deleting a resource group:
az group lock create --name "Cannot delete resource group" --lock-type CanNotDelete
Note
You need to have contributor permissions on a resource group to create or change locks.
To see the current locks on your resource group, use the az group lock list command:
az group lock list --output table
Clean up resources
If you tried any of the commands in this article, you can remove any resources you created by using the az group delete command:
az group delete --name MyResourceGroup
az group delete --name OtherResourceGroup
az group delete --name StorageGroups
This command removes the group and all the resources that it contains at once.
