Azure Database for MariaDB is a managed service that you use to run, manage, and scale highly available MariaDB databases in the cloud. In this quickstart, you use Bicep to create an Azure Database for MariaDB server in PowerShell or Azure CLI.

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

You'll need an Azure account with an active subscription. Create one for free.

Review the Bicep file

You create an Azure Database for MariaDB server with a defined set of compute and storage resources. To learn more, see Azure Database for MariaDB pricing tiers. You create the server within an Azure resource group.

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

The Bicep file defines five Azure resources:

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.

    az group create --name exampleRG --location eastus
az deployment group create --resource-group exampleRG --template-file main.bicep --parameters serverName=<server-name> administratorLogin=<admin-login>

    Note

    Replace <server-name> with the name of the server. Replace <admin-login> with the database administrator login name. The minimum required length is one character. You'll also be prompted to enter administratorLoginPassword. The minimum password length is eight characters.

    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

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
