Scale an elastic pool in Azure SQL Database using the Azure CLI

  • Artikkeli

Applies to: Azure SQL Database

This Azure CLI script example creates elastic pools in Azure SQL Database, moves pooled databases, and changes elastic pool compute sizes.

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, 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

# Scale an elastic pool in Azure SQL Database

# Variable block
let "randomIdentifier=$RANDOM*$RANDOM"
location="East US"
resourceGroup="msdocs-azuresql-rg-$randomIdentifier"
tag="scale-pool"
server="msdocs-azuresql-server-$randomIdentifier"
database="msdocsazuresqldb$randomIdentifier"
databaseAdditional="msdocs-azuresql-additional-db-$randomIdentifier"
login="azureuser"
password="Pa$$w0rD-$randomIdentifier"
pool="msdocs-azuresql-pool-$randomIdentifier"

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

echo "Creating $resourceGroup in $location..."
az group create --name $resourceGroup --location "$location" --tags $tag

echo "Creating $server in $location..."
az sql server create --name $server --resource-group $resourceGroup --location "$location" --admin-user $login --admin-password $password

echo "Creating $pool..."
az sql elastic-pool create --resource-group $resourceGroup --server $server --name $pool --edition GeneralPurpose --family Gen5 --capacity 2 --db-max-capacity 1 --db-min-capacity 1 --max-size 512GB

echo "Creating $database and $databaseAdditional on $server in $pool..."
az sql db create --resource-group $resourceGroup --server $server --name $database --elastic-pool $pool
az sql db create --resource-group $resourceGroup --server $server --name $databaseAdditional --elastic-pool $pool

echo "Scaling $pool..."
az sql elastic-pool update --resource-group $resourceGroup --server $server --name $pool --capacity 10 --max-size 1536GB

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 following commands. Each command in the table links to command-specific documentation.
