Create a container with a large partition key in an Azure Cosmos DB account using PowerShell

APPLIES TO: NoSQL

Note

We recommend that you use the Azure Az PowerShell module to interact with Azure. To get started, see Install Azure PowerShell. 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

# Reference: Az.CosmosDB | https://docs.microsoft.com/powershell/module/az.cosmosdb
# --------------------------------------------------
# Purpose
# Create Cosmos DB SQL API account, database, and container with dedicated throughput and no indexing policy
# --------------------------------------------------
Function New-RandomString{Param ([Int]$Length = 10) return $(-join ((97..122) + (48..57) | Get-Random -Count $Length | ForEach-Object {[char]$_}))}
# --------------------------------------------------
$uniqueId = New-RandomString -Length 7 # Random alphanumeric string for unique resource names
$apiKind = "Sql"
# --------------------------------------------------
# Variables - ***** SUBSTITUTE YOUR VALUES *****
$locations = @()
$locations += New-AzCosmosDBLocationObject -LocationName "East Us" -FailoverPriority 0 -IsZoneRedundant 0
$locations += New-AzCosmosDBLocationObject -LocationName "West Us" -FailoverPriority 1 -IsZoneRedundant 0

$resourceGroupName = "myResourceGroup" # Resource Group must already exist
$accountName = "cosmos-$uniqueId" # Must be all lower case
$consistencyLevel = "Session"
$tags = @{Tag1 = "MyTag1"; Tag2 = "MyTag2"; Tag3 = "MyTag3"}
$databaseName = "myDatabase"
$containerName = "myContainer"
$containerRUs = 400
$partitionKeyPath = "/myPartitionKey"
# --------------------------------------------------
Write-Host "Creating account $accountName"
$account = New-AzCosmosDBAccount -ResourceGroupName $resourceGroupName `
    -LocationObject $locations -Name $accountName -ApiKind $apiKind -Tag $tags `
    -DefaultConsistencyLevel $consistencyLevel `
    -EnableAutomaticFailover:$true

Write-Host "Creating database $databaseName"
$database = New-AzCosmosDBSqlDatabase -ParentObject $account -Name $databaseName

Write-Host "Creating container $containerName"
$container = New-AzCosmosDBSqlContainer `
    -ParentObject $database -Name $containerName `
    -Throughput $containerRUs -PartitionKeyVersion 2 `
    -PartitionKeyKind Hash -PartitionKeyPath $partitionKeyPath

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"
