  • Article

APPLIES TO: NoSQL MongoDB Cassandra Gremlin Table

Note

We recommend that you use the Azure Az PowerShell module to interact with Azure. See Install Azure PowerShell to get started. To learn how to migrate to the Az PowerShell module, see Migrate Azure PowerShell from AzureRM to Az.

This sample requires Azure PowerShell Az 5.4.0 or later. Run Get-Module -ListAvailable Az to see which versions are installed. If you need to install, see Install Azure PowerShell module.

Run Connect-AzAccount -Environment AzureChinaCloud to sign in to Azure.

Sample script

Note

You cannot modify regions and change other Azure Cosmos DB account properties in the same operation. These must be done as two separate operations.

Note

This sample demonstrates using a API for NoSQL account. To use this sample for other APIs, copy the related properties and apply to your API-specific script.
