Create an Azure Database for PostgreSQL - Flexible Server instance and configure a vNet rule using the Azure CLI
APPLIES TO:
Azure Database for PostgreSQL - Single Server
Azure Database for PostgreSQL - Flexible Server
This sample CLI script creates an Azure Database for PostgreSQL flexible server instance and configures a vNet rule.
If you don't have an Azure subscription, create an Azure free account before you begin.
Prerequisites
Use the Bash environment in Azure Cloud Shell. For more information, see Quickstart for Bash in Azure Cloud Shell.
If you prefer to run CLI reference commands locally, install the Azure CLI. If you're running on Windows or macOS, consider running Azure CLI in a Docker container. For more information, see How to run the Azure CLI in a Docker container.
If you're using a local installation, sign in to the Azure CLI by using the az login command. To finish the authentication process, follow the steps displayed in your terminal. For other sign-in options, see Sign in with the Azure CLI.
When you're prompted, install the Azure CLI extension on first use. For more information about extensions, see Use extensions with the Azure CLI.
Run az version to find the version and dependent libraries that are installed. To upgrade to the latest version, run az upgrade.
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 $subscription # ...or use 'az login'
For more information, see set active subscription or log in interactively
Run the script
# Create a PostgreSQL server and configure a vNet rule
# Variable block
let "randomIdentifier=$RANDOM*$RANDOM"
location="East US"
resourceGroup="msdocs-postgresql-rg-$randomIdentifier"
tag="create-postgresql-server"
server="msdocs-postgresql-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 PostgreSQL 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 postgres 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 postgres 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 postgresql server create | Creates an Azure Database for PostgreSQL flexible server instance that hosts the databases. |
az network vnet list-endpoint-services | Lists which services support VNET service tunneling in a given region. |
az network vnet create | Creates a virtual network. |
az network vnet subnet create | Creates a subnet and associates an existing NSG and route table. |
az network vnet subnet show | Shows details of a subnet. |
az postgresql server vnet-rule create | Creates a virtual network rule to allow access to an Azure Database for PostgreSQL flexible server instance. |
az group delete | Deletes a resource group including all nested resources. |
