Create a database and container for Azure Cosmos DB - SQL API



To interact with Azure, the Azure Az PowerShell module is recommended. 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 to sign in to Azure.

Sample script

This script creates a Cosmos account for SQL (Core) API in two regions with session level consistency, a database, and a container with a partition key, custom indexing policy, unique key policy, TTL, dedicated throughput, and last writer wins conflict resolution policy with a custom conflict resolution path that will be used when multipleWriteLocations=true.

# indexing policy with include, exclude, and composite paths, unique key, and conflict resolution

Clean up deployment

After the script sample has been run, the following command can be used to remove the resource group and all resources associated with it.

Remove-AzResourceGroup -ResourceGroupName "myResourceGroup"
