Create an Azure Cosmos DB account with virtual network service endpoints using Azure CLI

  • Article

APPLIES TO: NoSQL MongoDB Cassandra Gremlin Table

The script in this article creates a new virtual network with a front and back end subnet and enables service endpoints for Microsoft.AzureCosmosDB. It then retrieves the resource ID for this subnet and applies it to the Azure Cosmos DB account and enables service endpoints for the account.

This script uses a API for NoSQL account. To use this sample for other APIs, apply the enable-virtual-network and virtual-network-rules parameters in the script below to your API specific script.

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

# Service endpoint operations for an Azure Cosmos account

# Variable block
let "randomIdentifier=$RANDOM*$RANDOM"
location="East US"
resourceGroup="msdocs-cosmosdb-rg-$randomIdentifier"
tag="service-endpoints-cosmosdb"
account="msdocs-account-cosmos-$randomIdentifier" #needs to be lower case
vNet='msdocs-vnet-cosmosdb'
frontEnd='msdocs-front-end-cosmosdb'
backEnd='msdocs-back-end-cosmosdb'

# Create a resource group
echo "Creating $resourceGroup in $location..."
az group create --name $resourceGroup --location "$location" --tags $tag

# Create a virtual network with a front-end subnet
echo "Creating $vnet"
az network vnet create --name $vNet --resource-group $resourceGroup --address-prefix 10.0.0.0/16 --subnet-name $frontEnd --subnet-prefix 10.0.1.0/24

# Create a back-end subnet
echo "Creating $backend in $vNet"
az network vnet subnet create --name $backEnd --resource-group $resourceGroup --address-prefix 10.0.2.0/24 --vnet-name $vNet --service-endpoints Microsoft.AzureCosmosDB

# Retrieve the value of the service endpoint
svcEndpoint=$(az network vnet subnet show --resource-group $resourceGroup --name $backEnd --vnet-name $vNet --query 'id' -o tsv)

# Create a Cosmos DB account with default values and service endpoints
# Use appropriate values for --kind or --capabilities for other APIs
echo "Creating $account for CosmosDB"
az cosmosdb create --name $account --resource-group $resourceGroup --enable-virtual-network true --virtual-network-rules $svcEndpoint

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 following commands. Each command in the table links to command specific documentation.

Command Notes
az group create Creates a resource group in which all resources are stored.
az network vnet create Creates an Azure virtual network.
az network vnet subnet create Creates a subnet for an Azure virtual network.
az network vnet subnet show Returns a subnet for an Azure virtual network.
az cosmosdb create Creates an Azure Cosmos DB account.
az group delete Deletes a resource group including all nested resources.
