Manage Azure Cosmos DB for NoSQL resources using Azure CLI

  • บทความ

APPLIES TO: NoSQL

The following guide describes common commands to automate management of your Azure Cosmos DB accounts, databases and containers using Azure CLI. Reference pages for all Azure Cosmos DB CLI commands are available in the Azure CLI Reference. You can also find more examples in Azure CLI samples for Azure Cosmos DB, including how to create and manage Azure Cosmos DB accounts, databases and containers for MongoDB, Gremlin, Cassandra and API for Table.

Prerequisites

  • This article requires version 2.22.1 or later of the Azure CLI. If using Azure Cloud Shell, the latest version is already installed.

For Azure CLI samples for other APIs see CLI Samples for Cassandra, CLI Samples for API for MongoDB, CLI Samples for Gremlin, CLI Samples for Table

Important

Azure Cosmos DB resources cannot be renamed as this violates how Azure Resource Manager works with resource URIs.

Azure Cosmos DBAccounts

The following sections demonstrate how to manage the Azure Cosmos DB account, including:

Create an Azure Cosmos DB account

Create an Azure Cosmos DB account with API for NoSQL, Session consistency in West US and East US regions:

Important

The Azure Cosmos DB account name must be lowercase and less than 44 characters.

resourceGroupName='MyResourceGroup'
accountName='mycosmosaccount' #needs to be lower case and less than 44 characters

az cosmosdb create \
    -n $accountName \
    -g $resourceGroupName \
    --default-consistency-level Session \
    --locations regionName='West US' failoverPriority=0 isZoneRedundant=False \
    --locations regionName='East US' failoverPriority=1 isZoneRedundant=False

Add or remove regions

Create an Azure Cosmos DB account with two regions, add a region, and remove a region.

Note

You cannot simultaneously add or remove regions locations and change other properties for an Azure Cosmos DB account. Modifying regions must be performed as a separate operation than any other change to the account resource.

Note

This command allows you to add and remove regions but does not allow you to modify failover priorities or trigger a manual failover. See Set failover priority and Trigger manual failover.

Tip

When a new region is added, all data must be fully replicated and committed into the new region before the region is marked as available. The amount of time this operation takes will depend upon how much data is stored within the account. If an asynchronous throughput scaling operation is in progress, the throughput scale-up operation will be paused and will resume automatically when the add/remove region operation is complete.

resourceGroupName='myResourceGroup'
accountName='mycosmosaccount'

# Create an account with 2 regions
az cosmosdb create --name $accountName --resource-group $resourceGroupName \
    --locations regionName="West US" failoverPriority=0 isZoneRedundant=False \
    --locations regionName="East US" failoverPriority=1 isZoneRedundant=False

# Add a region
az cosmosdb update --name $accountName --resource-group $resourceGroupName \
    --locations regionName="West US" failoverPriority=0 isZoneRedundant=False \
    --locations regionName="East US" failoverPriority=1 isZoneRedundant=False \
    --locations regionName="South Central US" failoverPriority=2 isZoneRedundant=False

# Remove a region
az cosmosdb update --name $accountName --resource-group $resourceGroupName \
    --locations regionName="West US" failoverPriority=0 isZoneRedundant=False \
    --locations regionName="East US" failoverPriority=1 isZoneRedundant=False

Enable multiple write regions

Enable multi-region writes for an Azure Cosmos DB account

# Update an Azure Cosmos DB account from single write region to multiple write regions
resourceGroupName='myResourceGroup'
accountName='mycosmosaccount'

# Get the account resource id for an existing account
accountId=$(az cosmosdb show -g $resourceGroupName -n $accountName --query id -o tsv)

az cosmosdb update --ids $accountId --enable-multiple-write-locations true

Set failover priority

Set the failover priority for an Azure Cosmos DB account configured for service-managed failover

# Assume region order is initially 'West US'=0 'East US'=1 'South Central US'=2 for account
resourceGroupName='myResourceGroup'
accountName='mycosmosaccount'

# Get the account resource id for an existing account
accountId=$(az cosmosdb show -g $resourceGroupName -n $accountName --query id -o tsv)

# Make South Central US the next region to fail over to instead of East US
az cosmosdb failover-priority-change --ids $accountId \
    --failover-policies 'West US=0' 'South Central US=1' 'East US=2'

Enable service-managed failover

# Enable service-managed failover on an existing account
resourceGroupName='myResourceGroup'
accountName='mycosmosaccount'

# Get the account resource id for an existing account
accountId=$(az cosmosdb show -g $resourceGroupName -n $accountName --query id -o tsv)

az cosmosdb update --ids $accountId --enable-automatic-failover true

Trigger manual failover

Caution

Changing region with priority = 0 will trigger a manual failover for an Azure Cosmos DB account. Any other priority change will not trigger a failover.

Note

If you perform a manual failover operation while an asynchronous throughput scaling operation is in progress, the throughput scale-up operation will be paused. It will resume automatically when the failover operation is complete.

# Assume region order is initially 'West US=0' 'East US=1' 'South Central US=2' for account
resourceGroupName='myResourceGroup'
accountName='mycosmosaccount'

# Get the account resource id for an existing account
accountId=$(az cosmosdb show -g $resourceGroupName -n $accountName --query id -o tsv)

# Trigger a manual failover to promote East US 2 as new write region
az cosmosdb failover-priority-change --ids $accountId \
    --failover-policies 'East US=0' 'South Central US=1' 'West US=2'

List all account keys

Get all keys for an Azure Cosmos DB account.

# List all account keys
resourceGroupName='MyResourceGroup'
accountName='mycosmosaccount'

az cosmosdb keys list \
   -n $accountName \
   -g $resourceGroupName

List read-only account keys

Get read-only keys for an Azure Cosmos DB account.

# List read-only account keys
resourceGroupName='MyResourceGroup'
accountName='mycosmosaccount'

az cosmosdb keys list \
    -n $accountName \
    -g $resourceGroupName \
    --type read-only-keys

List connection strings

Get the connection strings for an Azure Cosmos DB account.

# List connection strings
resourceGroupName='MyResourceGroup'
accountName='mycosmosaccount'

az cosmosdb keys list \
    -n $accountName \
    -g $resourceGroupName \
    --type connection-strings

Regenerate account key

Regenerate a new key for an Azure Cosmos DB account.

# Regenerate secondary account keys
# key-kind values: primary, primaryReadonly, secondary, secondaryReadonly
az cosmosdb keys regenerate \
    -n $accountName \
    -g $resourceGroupName \
    --key-kind secondary

Azure Cosmos DB database

The following sections demonstrate how to manage the Azure Cosmos DB database, including:

Create a database

Create an Azure Cosmos DB database.

resourceGroupName='MyResourceGroup'
accountName='mycosmosaccount'
databaseName='database1'

az cosmosdb sql database create \
    -a $accountName \
    -g $resourceGroupName \
    -n $databaseName

Create a database with shared throughput

Create an Azure Cosmos DB database with shared throughput.

resourceGroupName='MyResourceGroup'
accountName='mycosmosaccount'
databaseName='database1'
throughput=400

az cosmosdb sql database create \
    -a $accountName \
    -g $resourceGroupName \
    -n $databaseName \
    --throughput $throughput

Migrate a database to autoscale throughput

resourceGroupName='MyResourceGroup'
accountName='mycosmosaccount'
databaseName='database1'

# Migrate to autoscale throughput
az cosmosdb sql database throughput migrate \
    -a $accountName \
    -g $resourceGroupName \
    -n $databaseName \
    -t 'autoscale'

# Read the new autoscale max throughput
az cosmosdb sql database throughput show \
    -g $resourceGroupName \
    -a $accountName \
    -n $databaseName \
    --query resource.autoscaleSettings.maxThroughput \
    -o tsv

Change database throughput

Increase the throughput of an Azure Cosmos DB database by 1000 RU/s.

resourceGroupName='MyResourceGroup'
accountName='mycosmosaccount'
databaseName='database1'
newRU=1000

# Get minimum throughput to make sure newRU is not lower than minRU
minRU=$(az cosmosdb sql database throughput show \
    -g $resourceGroupName -a $accountName -n $databaseName \
    --query resource.minimumThroughput -o tsv)

if [ $minRU -gt $newRU ]; then
    newRU=$minRU
fi

az cosmosdb sql database throughput update \
    -a $accountName \
    -g $resourceGroupName \
    -n $databaseName \
    --throughput $newRU

Prevent a database from being deleted

Put an Azure resource delete lock on a database to prevent it from being deleted. This feature requires locking the Azure Cosmos DB account from being changed by data plane SDKs. To learn more, see preventing changes from SDKs. Azure resource locks can also prevent a resource from being changed by specifying a ReadOnly lock type. For an Azure Cosmos DB database, it can be used to prevent throughput from being changed.

resourceGroupName='myResourceGroup'
accountName='mycosmosaccount'
databaseName='database1'

lockType='CanNotDelete' # CanNotDelete or ReadOnly
databaseParent="databaseAccounts/$accountName"
databaseLockName="$databaseName-Lock"

# Create a delete lock on database
az lock create --name $databaseLockName \
    --resource-group $resourceGroupName \
    --resource-type Microsoft.DocumentDB/sqlDatabases \
    --lock-type $lockType \
    --parent $databaseParent \
    --resource $databaseName

# Delete lock on database
lockid=$(az lock show --name $databaseLockName \
        --resource-group $resourceGroupName \
        --resource-type Microsoft.DocumentDB/sqlDatabases \
        --resource $databaseName \
        --parent $databaseParent \
        --output tsv --query id)
az lock delete --ids $lockid

containerName='container1'
partitionKey='/myPartitionKey'
throughput=400

# Generate a unique 10 character alphanumeric string to ensure unique resource names
uniqueId=$(env LC_CTYPE=C tr -dc 'a-z0-9' < /dev/urandom | fold -w 10 | head -n 1)

# Define the index policy for the container, include spatial and composite indexes
