Quickstart: Create an Azure Cosmos DB for MongoDB vCore cluster by using a Bicep template

  • Article

APPLIES TO: MongoDB vCore

In this quickstart, you create a new Azure Cosmos DB for MongoDB vCore cluster. This cluster contains all of your MongoDB resources: databases, collections, and documents. The cluster provides a unique endpoint for various tools and SDKs to connect to Azure Cosmos DB and perform everyday operations.

Prerequisites

Review the Bicep file

The Bicep file used in this quickstart is from Azure Quickstart Templates.

@description('Azure Cosmos DB MongoDB vCore cluster name')
@maxLength(44)
param clusterName string = 'msdocs-${uniqueString(resourceGroup().id)}'

@description('Location for the cluster.')
param location string = resourceGroup().location

@description('Username for admin user')
param adminUsername string

@secure()
@description('Password for admin user')
@minLength(8)
@maxLength(128)
param adminPassword string

resource cluster 'Microsoft.DocumentDB/mongoClusters@2022-10-15-preview' = {
  name: clusterName
  location: location
  properties: {
    administratorLogin: adminUsername
    administratorLoginPassword: adminPassword
    nodeGroupSpecs: [
        {
            kind: 'Shard'
            shardCount: 1
            sku: 'M40'
            diskSizeGB: 128
            enableHa: false
        }
    ]
  }
}

resource firewallRules 'Microsoft.DocumentDB/mongoClusters/firewallRules@2022-10-15-preview' = {
  parent: cluster
  name: 'AllowAllAzureServices'
  properties: {
    startIpAddress: '0.0.0.0'
    endIpAddress: '0.0.0.0'
  }
}

Note

Kindly note that in the above code, shardGroupSpecs is called nodeGroupSpecs.

Two Azure resources are defined in the Bicep file:

Deploy the Bicep file

Create an Azure Cosmos DB for MongoDB vCore cluster by using the Bicep template.

  1. Create shell variables for resourceGroupName, and location

    # Variable for resource group name and location
resourceGroupName="msdocs-cosmos-quickstart-rg"
location="eastus"

  2. If you haven't already, sign in to the Azure CLI using the az login command.

  3. Use the az group create command to create a new resource group in your subscription.

    az group create \
    --name $resourceGroupName \
    --location $location

  4. Use az deployment group create to deploy the bicep template. You're then prompted to enter a value for the adminUsername and adminPassword parameters.

    az deployment group create \
    --resource-group $resourceGroupName \
    --template-file 'main.bicep'

    Tip

    Alternatively, use the --parameters option to pass in a parameters file with pre-defined values.

    az deployment group create \
    --resource-group $resourceGroupName \
    --template-file 'main.bicep' \
    --parameters @main.parameters.json

    This example JSON file injects clusteradmin and P@ssw.rd values for the adminUsername and adminPassword parameters respectively.

    {
  "$schema": "https://schema.management.azure.com/schemas/2015-01-01/deploymentParameters.json#",
  "contentVersion": "1.0.0.0",
  "parameters": {
    "adminUsername": {
      "value": "clusteradmin"
    },
    "adminPassword": {
      "value": "P@ssw.rd"
    }
  }
}

  5. Wait for the deployment operation to complete before moving on.

Review deployed resources

List the resources deployed by the Bicep template to your target resource group.

  1. Use az resource list to get a list of resources in your resource group.

    az resource list \
    --resource-group $resourceGroupName \
    --location $location \
    --output tsv

  2. In the example output, look for resources that have a type of Microsoft.DocumentDB/mongoClusters. Here's an example of the type of output to expect:

    Name                  ResourceGroup                Location    Type                                Status
--------------------  ---------------------------  ----------  ----------------------------------  --------
msdocs-sz2dac3xtwzzu  msdocs-cosmos-quickstart-rg  eastus      Microsoft.DocumentDB/mongoClusters

Clean up resources

When you're done with your Azure Cosmos DB for MongoDB vCore cluster, you can delete the Azure resources you created so you don't incur more charges.

  1. Use az group delete to remove the resource group from your subscription.

    az group delete \
    --name $resourceGroupName
