Create a MariaDB server and configure a vNet rule using the Azure CLI

This sample CLI script creates an Azure Database for MariaDB server and configures a vNet rule.

If you don't have an Azure subscription, create an Azure free account before you begin.

Prerequisites

Sample script

Launch Azure Cloud Shell

The Azure Cloud Shell is a free interactive shell that you can use to run the steps in this article. It has common Azure tools preinstalled and configured to use with your account.

To open the Cloud Shell, just select Try it from the upper right corner of a code block. You can also launch Cloud Shell in a separate browser tab by going to https://shell.azure.com.

When Cloud Shell opens, verify that Bash is selected for your environment. Subsequent sessions will use Azure CLI in a Bash environment, Select Copy to copy the blocks of code, paste it into the Cloud Shell, and press Enter to run it.

Sign in to Azure

Cloud Shell is automatically authenticated under the initial account signed-in with. Use the following script to sign in using a different subscription, replacing <Subscription ID> with your Azure Subscription ID. If you don't have an Azure subscription, create an Azure free account before you begin.

subscription="<subscriptionId>" # add subscription here

az account set -s $subscription # ...or use 'az login'

For more information, see set active subscription or log in interactively

Run the script

# Create MariaDB server in vNet

# Variable block
let "randomIdentifier=$RANDOM*$RANDOM"
location="East US"
resourceGroup="msdocs-mariadb-rg-$randomIdentifier"
tag="create-mariadb-server"
server="msdocs-mariadb-server-$randomIdentifier"
sku="GP_Gen5_2"
vNet="vNet-$randomIdentifier"
vNetAddressPrefix="10.0.0.0/16"
subnet="subnet-$randomIdentifier"
subnetAddressPrefix="10.0.1.0/24"
rule="rule-$randomIdentifier"
login="azureuser"
password="Pa$$w0rD-$randomIdentifier"

echo "Using resource group $resourceGroup with login: $login, password: $password..."

# Create a resource group
echo "Creating $resourceGroup in $location..."
az group create --name $resourceGroup --location "$location" --tags $tag

# Create a MariaDB server in the resource group
# Name of a server maps to DNS name and is thus required to be globally unique in Azure.
echo "Creating $server in $location..."
az mariadb server create --name $server --resource-group $resourceGroup --location "$location" --admin-user $login --admin-password $password --sku-name $sku

# Get available service endpoints for Azure region output is JSON
echo "List of available service endpoints for $location"
az network vnet list-endpoint-services --location "$location"

# Add Azure SQL service endpoint to a subnet while creating the virtual network
echo "Adding service endpoint to $subnet in $vNet"
az network vnet create --resource-group $resourceGroup --name $vNet --address-prefixes $vNetAddressPrefix --location "$location"

# Creates the service endpoint
echo "Creating a service endpoint to $subnet in $vNet"
az network vnet subnet create --resource-group $resourceGroup --name $subnet --vnet-name $vNet --address-prefix $subnetAddressPrefix --service-endpoints Microsoft.SQL

# View service endpoints configured on a subnet
echo "Viewing the service endpoint to $subnet in $vNet"
az network vnet subnet show --resource-group $resourceGroup --name $subnet --vnet-name $vNet

# Create a VNet rule on the server to secure it to the subnet
# Note: resource group (-g) parameter is where the database exists.
# VNet resource group if different should be specified using subnet id (URI) instead of subnet, VNet pair.
echo "Creating a VNet rule on $server to secure it to $subnet in $vNet"
az mariadb server vnet-rule create --name $rule --resource-group $resourceGroup --server $server --vnet-name $vNet --subnet $subnet

Clean up resources

Use the following command to remove the resource group and all resources associated with it using the az group delete command - unless you have an ongoing need for these resources. Some of these resources may take a while to create, as well as to delete.

az group delete --name $resourceGroup

Sample reference

This script uses the commands outlined in the following table:

Command Notes
az group create Creates a resource group in which all resources are stored.
az mariadb server create Creates a MariaDB server that hosts the databases.
az network vnet list-endpoint-services List which services support VNET service tunneling in a given region.
az network vnet create Creates a virtual network.
az network vnet subnet create Create a subnet and associate an existing NSG and route table.
az network vnet subnet show Shows details of a subnet.
az mariadb server vnet-rule create Create a virtual network rule to allows access to a MariaDB server.
az group delete Deletes a resource group including all nested resources.
