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
--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.
Persist a resource group
Parameter persistence allows you to reuse values for certain parameters, including resource groups.
First, turn on the persistence feature by using the az config param-persist on command:
az config param-persist on
After turning on persistence, create another resource group:
az group create --name OtherResourceGroup --location eastus
As long as persistence is on, your can leave the
--resource-group parameter out of future commands. The following command creates a storage account in the OtherResourceGroup group:
az storage account create --name storage135 --location eastus --sku Standard_LRS
Specifying a resource group in the command takes precedence. The following command creates a storage group in a resource group called StorageGroups:
az storage account create --resource-group StorageGroups --name storage136 --location eastus --sku Standard_LRS
Once you specify another resource group as a value, however, Azure CLI resets the persisted value. New commands use StorageGroups as the resource group. You can see the persisted values by using the az config param-persist show command:
az config param-persist show
This command shows you the current persisted values. These values are stored in a file called local_context_<username> in a hidden directory called .azure. Azure CLI creates the directory in your current location when you first create a persistent value.
When you're done using persisted parameters, run the az config param-persist off command:
az config param-persist off
Azure CLI saves your persisted values. You can see them in the local context file. If you turn on parameter persistence again, those values are already set.
For more information about using the az config param-persist commands, see Use persisted parameters to simplify sequential Azure CLI commands.
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.
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.
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.
You can remove the persistent parameters by running the az config param-persist delete command:
az config param-persist delete --all
