Use CLI to scale an elastic pool in Azure SQL Database

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

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

Use Azure Cloud Shell

Azure hosts Azure Cloud Shell, an interactive shell environment that you can use through your browser. Cloud Shell lets you use either bash or PowerShell to work with Azure services. You can use the Cloud Shell pre-installed commands to run the code in this article without having to install anything on your local environment.

To launch Azure Cloud Shell:

Option Example/Link
Select Try It in the upper-right corner of a code block. Selecting Try It doesn't automatically copy the code to Cloud Shell. Example of Try It for Azure Cloud Shell
Go to https://shell.azure.com or select the Launch Cloud Shell button to open Cloud Shell in your browser. Launch Cloud Shell in a new window
Select the Cloud Shell button on the top-right menu bar in the Azure portal. Cloud Shell button in the Azure portal

To run the code in this article in Azure Cloud Shell:

  1. Launch Cloud Shell.

  2. Select the Copy button on a code block to copy the code.

  3. Paste the code into the Cloud Shell session with Ctrl+Shift+V on Windows and Linux, or Cmd+Shift+V on macOS.

  4. Press Enter to run the code.

If you choose to install and use the CLI locally, this topic requires that you are running the Azure CLI version 2.0 or later. Run az --version to find the version. If you need to install or upgrade, see Install the Azure CLI.

Sample script

#!/bin/bash

# set execution context (if necessary)
az account set --subscription <replace with your subscription name or id>

# Set the resource group name and location for your server
resourceGroupName=myResourceGroup-$RANDOM
location=westus2

# Set an admin login and password for your database
adminlogin=ServerAdmin
password=`openssl rand -base64 16`
# password=<EnterYourComplexPasswordHere1>

# The logical server name has to be unique in the system
servername=server-$RANDOM

# Create a resource group
az group create \
--name $resourceGroupName \
--location $location

# Create a server
az sql server create \
    --name $servername \
    --resource-group $resourceGroupName \
    --location $location \
    --admin-user $adminlogin \
    --admin-password $password

# Create a pool with 5 vCores and a max storage of 756 GB
az sql elastic-pool create \
    --resource-group $resourceGroupName \
    --server $servername \
    --name samplepool \
    --edition GeneralPurpose \
    --family Gen4 \
    --capacity 5 \
    --db-max-capacity 4 \
    --db-min-capacity 1 \
    --max-size 756GB

# Create two database in the pool
az sql db create \
    --resource-group $resourceGroupName \
    --server $servername \
    --name myFirstSampleDatabase \
    --elastic-pool samplepool

az sql db create \
    --resource-group $resourceGroupName \
    --server $servername \
    --name mySecondSampleDatabase \
    --elastic-pool samplepool

# Scale up to the pool to 10 vCores
az sql elastic-pool update \
    --resource-group $resourceGroupName \
    --server $servername \
    --name samplepool \
    --capacity 10 \
    --max-size 1536GB

# Echo random password
echo $password

Clean up deployment

Use the following command to remove the resource group and all resources associated with it.

az group delete --name $resourceGroupName

Script explanation

This script uses the following commands to create a resource group, SQL Database server, single database, and SQL Database firewall rules. Each command in the table links to command specific documentation.

Command Notes
az group create Creates a resource group in which all resources are stored.
az sql server create Creates a SQL Database server that hosts single databases and elastic pools.
az sql elastic-pools create Creates an elastic pool.
az sql db create Creates a single or pooled database.
az sql elastic-pools update Updates an elastic pool, in this example changes the assigned eDTU.
az group delete Deletes a resource group including all nested resources.
