Manage Azure Cosmos DB for MongoDB resources using Bicep

  • Article

APPLIES TO: MongoDB

In this article, you learn how to use Bicep to deploy and manage your Azure Cosmos DB accounts for API for MongoDB, databases, and collections.

This article shows Bicep samples for API for MongoDB accounts. You can also find Bicep samples for SQL, Cassandra, Gremlin, and Table APIs.

Important

  • Account names are limited to 44 characters, all lowercase.
  • To change the throughput values, redeploy the template with updated RU/s.
  • When you add or remove locations to an Azure Cosmos DB account, you can't simultaneously modify other properties. These operations must be done separately.

To create any of the Azure Cosmos DB resources below, copy the following example into a new bicep file. You can optionally create a parameters file to use when deploying multiple instances of the same resource with different names and values. There are many ways to deploy Azure Resource Manager templates including, Azure CLI, Azure PowerShell and Cloud Shell.

API for MongoDB with autoscale provisioned throughput
