Quickstart: Use an ARM template to create an Azure Database for PostgreSQL - Flexible Server instance

  • Article

APPLIES TO: Azure Database for PostgreSQL - Flexible Server

Azure Database for PostgreSQL flexible server is a managed service that you use to run, manage, and scale highly available PostgreSQL databases in the cloud. You can use an Azure Resource Manager template (ARM template) to provision an Azure Database for PostgreSQL flexible server instance to deploy multiple servers or multiple databases on a server.

An Azure Resource Manager template is a JavaScript Object Notation (JSON) file that defines the infrastructure and configuration for your project. The template uses declarative syntax. You describe your intended deployment without writing the sequence of programming commands to create the deployment.

Azure Resource Manager is the deployment and management service for Azure. It provides a management layer that enables you to create, update, and delete resources in your Azure account. You use management features, like access control, locks, and tags, to secure and organize your resources after deployment. To learn about Azure Resource Manager templates, see Template deployment overview.

Prerequisites

An Azure account with an active subscription. Create one for free.

Review the template

An Azure Database for PostgreSQL flexible server instance is the parent resource for one or more databases within a region. It provides the scope for management policies that apply to its databases: login, firewall, users, roles, and configurations.

Create a postgres-flexible-server-template.json file and copy the following JSON script into it.

}

These resources are defined in the template:

Deploy the template

Select Try it from the following PowerShell code block to open Azure Cloud Shell.

$serverName = Read-Host -Prompt "Enter a name for the new Azure Database for PostgreSQL flexible server instance"
$resourceGroupName = Read-Host -Prompt "Enter a name for the new resource group where the server will exist"
$location = Read-Host -Prompt "Enter an Azure region (for example, centralus) for the resource group"
$adminUser = Read-Host -Prompt "Enter the Azure Database for PostgreSQL flexible server instance's administrator account name"
$adminPassword = Read-Host -Prompt "Enter the administrator password" -AsSecureString

New-AzResourceGroup -Name $resourceGroupName -Location $location # Use this command when you need to create a new resource group for your deployment
New-AzResourceGroupDeployment -ResourceGroupName $resourceGroupName `
    -TemplateFile "postgres-flexible-server-template.json" `
    -serverName $serverName `
    -administratorLogin $adminUser `
    -administratorLoginPassword $adminPassword

Read-Host -Prompt "Press [ENTER] to continue ..."

Review deployed resources

Follow these steps to verify if your server was created in Azure.

APPLIES TO: Azure Database for PostgreSQL - Flexible Server

  1. In the Azure portal, search for and select Azure Database for PostgreSQL Flexible Servers.
  2. In the database list, select your new server to view the Overview page to manage the server.

Clean up resources

Keep this resource group, server, and single database if you want to go to the Next steps. The next steps show you how to connect and query your database using different methods.

To delete the resource group:
