Find an existing Azure Cosmos DB free-tier account in a subscription using Azure CLI

  • Artikkeli

APPLIES TO: NoSQL MongoDB Cassandra Gremlin Table

The script in this article demonstrates how to locate an Azure Cosmos DB free-tier account within a subscription.

Each Azure subscription can have up to one Azure Cosmos DB free-tier account. If you're trying to create a free-tier account, the option may be disabled in the Azure portal, or you get an error when attempting to create a free-tier account. If either of these issues occur, use this script to locate the name of the existing free-tier account, and the resource group it belongs to.

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

Prerequisites

  • This article requires version 2.9.1 or later of the Azure CLI. If using Azure Cloud Shell, the latest version is already installed.

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

# Azure Cosmos DB offers one free-tier account per subscription
# This script will find if you have a free-tier account and output 
# the name of the Cosmos DB account and its resource group 


# These can remain commented out if running in Azure Cloud Shell

#az login
#az account set -s {your subscription id}

isFound=0

# Iterate through all the resource groups in the subscription
for rg in $(az group list --query "[].name" --output tsv) 
do

    echo "Checking resource group: $rg"
    
    # Return the Cosmos DB account in the resource group marked as free tier
    ft=$(az cosmosdb list -g $rg --query "[?enableFreeTier].name" --output tsv)
    
    if [ ${#ft} -gt 0 ]; then
        
        echo "$ft is a free tier account in resource group: $rg"
        isFound=1
        break
    
    fi

done

if [ $isFound -eq 0 ]; then
    echo "No Free Tier accounts in subscription"
fi
