APPLIES TO: Azure Database for PostgreSQL - Flexible Server

This sample CLI script lists all available configuration parameters and their allowable values for Azure Database for PostgreSQL flexible server, and sets the log_retention_days to a value that is other than the default one.

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 subscriptionId with your Azure subscription ID.

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

Azure CLI 
subscription="subscriptionId" # Set Azure subscription ID here

az account set -s $subscription # ...or use 'az login'

For more information, see set active subscription or log in interactively.

Run the script

Azure CLI 
# List and update configurations of an Azure Database for PostgreSQL server

# Variable block
let "randomIdentifier=$RANDOM*$RANDOM"
location="East US"
resourceGroup="msdocs-postgresql-rg-$randomIdentifier"
tag="change-server-cofigurations-postgresql"
server="msdocs-postgresql-server-$randomIdentifier"
sku="GP_Gen5_2"
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

# Display all available configurations with valid values of an Azure Database for PostgreSQL server
az postgres server configuration list --resource-group $resourceGroup --server-name $server

# Set value of **log_retention_days**
echo "Setting value of the log_retention_days setting on $server"
az postgres server configuration set --resource-group $resourceGroup --server-name $server --name log_retention_days --value 7

# Check the value of **log_retention_days**
echo "Checking the value of the log_retention_days setting on $server"
az postgres server configuration show --resource-group $resourceGroup --server-name $server --name log_retention_days

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.

Azure CLI 
az group delete --name $resourceGroup
