Delete resources from Azure Arc-enabled data services

  • Article

This article describes how to delete Azure Arc-enabled data service resources from Azure.

Warning

When you delete resources as described in this article, these actions are irreversible.

The information in this article applies to resources in Azure Arc-enabled data services. To delete resources in Azure, review the information at Azure Resource Manager resource group and resource deletion.

Before

Before you delete a resource such as Azure Arc SQL managed instance or Azure Arc data controller, you need to export and upload the usage information to Azure for accurate billing calculation by following the instructions described in Upload billing data to Azure - Indirectly connected mode.

Direct connectivity mode

When a cluster is connected to Azure with direct connectivity mode, use the Azure portal to manage the resources. Use the portal for all create, read, update, & delete (CRUD) operations for data controller, managed instances, and PostgreSQL servers.

From Azure portal:

  1. Browse to the resource group and delete the Azure Arc data controller
  2. Select the Azure Arc-enabled Kubernetes cluster, go to the Overview page
    • Select Extensions under Settings
    • In the Extensions page, select the Azure Arc data services extension (of type microsoft.arcdataservices) and click on Uninstall
  3. Optionally delete the Custom Location that the Azure Arc data controller is deployed to.
  4. Optionally, you can also delete the namespace on your Kubernetes cluster if there are no other resources created in the namespace.

See Manage Azure resources by using the Azure portal.

Indirect connectivity mode

In indirect connect mode, deleting an instance from Kubernetes will not remove it from Azure and deleting an instance from Azure will not remove it from Kubernetes. For indirect connect mode, deleting a resource is a two step process and this will be improved in the future. Kubernetes will be the source of truth and the portal will be updated to reflect it.

In some cases, you may need to manually delete Azure Arc-enabled data services resources in Azure. You can delete these resources using any of the following options.

Delete an entire resource group

If you have been using a specific and dedicated resource group for Azure Arc-enabled data services and you want to delete everything inside of the resource group you can delete the resource group which will delete everything inside of it.

You can delete a resource group in the Azure portal by doing the following:

  • Browse to the resource group in the Azure portal where the Azure Arc-enabled data services resources have been created.
  • Click the Delete resource group button.
  • Confirm the deletion by entering the resource group name and click Delete.

Delete specific resources in the resource group

You can delete specific Azure Arc-enabled data services resources in a resource group in the Azure portal by doing the following:

  • Browse to the resource group in the Azure portal where the Azure Arc-enabled data services resources have been created.
  • Select all the resources to be deleted.
  • Click on the Delete button.
  • Confirm the deletion by typing 'yes' and click Delete.

Delete resources using the Azure CLI

You can delete specific Azure Arc-enabled data services resources using the Azure CLI.

Delete SQL managed instance resources using the Azure CLI

To delete SQL managed instance resources from Azure using the Azure CLI replace the placeholder values in the command below and run it.

az resource delete --name <sql instance name> --resource-type Microsoft.AzureArcData/sqlManagedInstances --resource-group <resource group name>

#Example
#az resource delete --name sql1 --resource-type Microsoft.AzureArcData/sqlManagedInstances --resource-group rg1

Delete PostgreSQL server resources using the Azure CLI

To delete a PostgreSQL server resource from Azure using the Azure CLI replace the placeholder values in the command below and run it.

az resource delete --name <postgresql instance name> --resource-type Microsoft.AzureArcData/postgresInstances --resource-group <resource group name>

#Example
#az resource delete --name pg1 --resource-type Microsoft.AzureArcData/postgresInstances --resource-group rg1

Delete Azure Arc data controller resources using the Azure CLI

Note

Before deleting an Azure Arc data controller, you should delete all of the database instance resources that it is managing.

To delete an Azure Arc data controller from Azure using the Azure CLI replace the placeholder values in the command below and run it.

az resource delete --name <data controller name> --resource-type Microsoft.AzureArcData/dataControllers --resource-group <resource group name>

#Example
#az resource delete --name dc1 --resource-type Microsoft.AzureArcData/dataControllers --resource-group rg1

Delete a resource group using the Azure CLI

You can also use the Azure CLI to delete a resource group.
