Create an Azure Database for PostgreSQL - Flexible Server instance and configure a firewall rule using the Azure CLI

  • Article

APPLIES TO: Azure Database for PostgreSQL - Flexible Server

This sample CLI script creates an Azure Database for PostgreSQL flexible server instance and configures a server-level firewall rule. Once the script has been successfully run, the Azure Database for PostgreSQL flexible server instance can be accessed from all Azure services and the configured IP address.

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 an Azure Database for PostgreSQL server and configure a firewall rule

# Variable block
let "randomIdentifier=$RANDOM*$RANDOM"
location="East US"
resourceGroup="msdocs-postgresql-rg-$randomIdentifier"
tag="create-postgresql-server-and-firewall-rule"
server="msdocs-postgresql-server-$randomIdentifier"
sku="GP_Gen5_2"
login="azureuser"
password="Pa$$w0rD-$randomIdentifier"
# Specify appropriate IP address values for your environment
# to limit / allow access to the PostgreSQL server
startIp=0.0.0.0
endIp=0.0.0.0
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
# Configure a firewall rule for the server 
echo "Configuring a firewall rule for $server for the IP address range of $startIp to $endIp"
az postgres server firewall-rule create --resource-group $resourceGroup --server $server --name AllowIps --start-ip-address $startIp --end-ip-address $endIp
# List firewall rules for the server
echo "List of server-based firewall rules for $server"
az postgres server firewall-rule list --resource-group $resourceGroup --server-name $server
# You may use the switch `--output table` for a more readable table format as the output.

Clean up deployment

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 postgres server create Creates an Azure Database for PostgreSQL flexible server instance that hosts the databases.
az postgres server firewall create Creates a firewall rule to allow access to the server and databases under it from the entered IP address range.
az group delete Deletes a resource group including all nested resources.
