Quickstart: Create an Azure SQL Managed Instance using Bicep

This quickstart focuses on the process of deploying a Bicep file to create an Azure SQL Managed Instance and vNet. Azure SQL Managed Instance is an intelligent, fully managed, scalable cloud database, with almost 100% feature parity with the SQL Server database engine.

Bicep is a domain-specific language (DSL) that uses declarative syntax to deploy Azure resources. It provides concise syntax, reliable type safety, and support for code reuse. Bicep offers the best authoring experience for your infrastructure-as-code solutions in Azure.

Prerequisites

If you don't have an Azure subscription, create a trial account.

Review the Bicep file

The Bicep file used in this quickstart is from Azure Quickstart Templates.

These resources are defined in the Bicep file:

• Microsoft.Network/networkSecurityGroups
• Microsoft.Network/routeTables
• Microsoft.Network/virtualNetworks
• Microsoft.Sql/managedinstances

Deploy the Bicep file

1. Save the Bicep file as main.bicep to your local computer.

2. Deploy the Bicep file using either Azure CLI or Azure PowerShell.

   • CLI
   • PowerShell

   az group create --name exampleRG --location chinaeast2
   az deployment group create --resource-group exampleRG --template-file main.bicep --parameters managedInstanceName=<instance-name> administratorLogin=<admin-login>
   

When the deployment finishes, you should see a message indicating the deployment succeeded.

Review deployed resources

Use the Azure portal, Azure CLI, or Azure PowerShell to list the deployed resources in the resource group.

az resource list --resource-group exampleRG

Get-AzResource -ResourceGroupName exampleRG

Clean up resources

When no longer needed, use the Azure portal, Azure CLI, or Azure PowerShell to delete the resource group and its resources.

az group delete --name exampleRG

Remove-AzResourceGroup -Name exampleRG
