Manage your Azure AI Search service with the Azure CLI

  • Artikkeli

You can run Azure CLI commands and scripts on Windows, macOS, Linux, or in Azure Cloud Shell to create and configure Azure AI Search.

Use the az search module to perform the following tasks:

Occasionally, questions are asked about tasks not on the above list.

You can't change a server name, region, or tier programmatically or in the Azure portal. Dedicated resources are allocated when a service is created. As such, changing the underlying hardware (location or node type) requires a new service.

You can't use tools or APIs to transfer content, such as an index, from one service to another. Within a service, programmatic creation of content is through Search Service REST API or an SDK such as Azure SDK for .NET. While there are no dedicated commands for content migration, you can write script that calls REST API or a client library to create and load indexes on a new service.

Preview administration features are typically not available in the az search module. If you want to use a preview feature, use the Management REST API and a preview API version.

Prerequisites

Azure CLI versions are listed on GitHub.

The az search module extends the Azure CLI with full parity to the stable versions of the Search Management REST APIs.

List services in a subscription

The following commands are from az resource, returning information about existing resources and services already provisioned in your subscription. If you don't know how many search services are already created, these commands return that information, saving you a trip to the Azure portal.

The first command returns all search services.

az resource list --resource-type Microsoft.Search/searchServices --output table

From the list of services, return information about a specific resource.

az resource list --name <search-service-name>

List all az search commands

You can view information on the subgroups and commands available in az search from within the CLI. Alternatively, you can review the documentation.

To view the subgroups available within az search, run the following command.

az search --help

The response should look similar to the following output.

Group
    az search : Manage Azure Search services, admin keys and query keys.
        WARNING: This command group is in preview and under development. Reference and support
        levels: https://aka.ms/CLI_refstatus
Subgroups:
    admin-key                    : Manage Azure Search admin keys.
    private-endpoint-connection  : Manage Azure Search private endpoint connections.
    private-link-resource        : Manage Azure Search private link resources.
    query-key                    : Manage Azure Search query keys.
    service                      : Manage Azure Search services.
    shared-private-link-resource : Manage Azure Search shared private link resources.

For more specific examples, use: az find "az search"

Within each subgroup, multiple commands are available. You can see the available commands for the service subgroup by running the following line.

az search service --help

You can also see the arguments available for a particular command.

az search service create --help

Get search service information

If you know the resource group containing your search service, run az search service show to return the service definition, including name, region, tier, and replica and partition counts. For this command, provide the resource group that contains the search service.

az search service show --name <service-name> --resource-group <search-service-resource-group-name>

Create or delete a service

To create a new search service, use the az search service create command.

az search service create \
    --name <service-name> \
    --resource-group <search-service-resource-group-name> \
    --sku Standard \
    --partition-count 1 \
    --replica-count 1

Results should look similar to the following output:

{
  "hostingMode": "default",
  "id": "/subscriptions/<alphanumeric-subscription-ID>/resourceGroups/demo-westus/providers/Microsoft.Search/searchServices/my-demo-searchapp",
  "identity": null,
  "location": "West US",
  "name": "my-demo-searchapp",
  "networkRuleSet": {
    "bypass": "None",
    "ipRules": []
  },
  "partitionCount": 1,
  "privateEndpointConnections": [],
  "provisioningState": "succeeded",
  "publicNetworkAccess": "Enabled",
  "replicaCount": 1,
  "resourceGroup": "demo-westus",
  "sharedPrivateLinkResources": [],
  "sku": {
    "name": "standard"
  },
  "status": "running",
  "statusDetails": "",
  "tags": null,
  "type": "Microsoft.Search/searchServices"
}

az search service delete removes the service and its data.

az search service delete --name <service-name> \
                         --resource-group  <search-service-resource-group-name> \

Create a service with IP rules

Depending on your security requirements, you might want to create a search service with an IP firewall configured. To do so, pass the Public IP (v4) addresses or CIDR ranges to the ip-rules argument as shown below. Rules should be separated by a comma (,) or semicolon (;).

az search service create \
    --name <search-service-name> \
    --resource-group <search-service-resource-group-name> \
    --sku Standard \
    --partition-count 1 \
    --replica-count 1 \
    --ip-rules "55.5.63.73;52.228.215.197;101.37.221.205"

Create a service with a system assigned managed identity

In some cases, such as when using managed identity to connect to a data source, you need to turn on system assigned managed identity. This is done by adding --identity-type SystemAssigned to the command.

az search service create \
    --name <search-service-name> \
    --resource-group <search-service-resource-group-name> \
    --sku Standard \
    --partition-count 1 \
    --replica-count 1 \
    --identity-type SystemAssigned

Create a service with a private endpoint

Private Endpoints for Azure AI Search allow a client on a virtual network to securely access data in a search index over a Private Link. The private endpoint uses an IP address from the virtual network address space for your search service. Network traffic between the client and the search service traverses over the virtual network and a private link on the Microsoft backbone network, eliminating exposure from the public internet. For more information, please refer to the documentation on creating a private endpoint for Azure AI Search.

The following example shows how to create a search service with a private endpoint.

First, deploy a search service with PublicNetworkAccess set to Disabled.

az search service create \
    --name <search-service-name> \
    --resource-group <search-service-resource-group-name> \
    --sku Standard \
    --partition-count 1 \
    --replica-count 1 \
    --public-access Disabled

Next, create a virtual network and the private endpoint.

# Create the virtual network
az network vnet create \
    --resource-group <vnet-resource-group-name> \
    --location "West US" \
    --name <virtual-network-name> \
    --address-prefixes 10.1.0.0/16 \
    --subnet-name <subnet-name> \
    --subnet-prefixes 10.1.0.0/24

# Update the subnet to disable private endpoint network policies
az network vnet subnet update \
    --name <subnet-name> \
    --resource-group <vnet-resource-group-name> \
    --vnet-name <virtual-network-name> \
    --disable-private-endpoint-network-policies true

# Get the id of the search service
id=$(az search service show \
    --resource-group <search-service-resource-group-name> \
    --name <search-service-name> \
    --query [id] \
    --output tsv)

# Create the private endpoint
az network private-endpoint create \
    --name <private-endpoint-name> \
    --resource-group <private-endpoint-resource-group-name> \
    --vnet-name <virtual-network-name> \
    --subnet <subnet-name> \
    --private-connection-resource-id $id \
    --group-id searchService \
    --connection-name <private-link-connection-name>

Finally, create a private DNS Zone.

## Create private DNS zone
az network private-dns zone create \
    --resource-group <private-dns-resource-group-name> \
    --name "privatelink.search.windows.net"

## Create DNS network link
az network private-dns link vnet create \
    --resource-group <private-dns-resource-group-name> \
    --zone-name "privatelink.search.windows.net" \
    --name "myLink" \
    --virtual-network <virtual-network-name> \
    --registration-enabled false

## Create DNS zone group
az network private-endpoint dns-zone-group create \
   --resource-group <private-endpoint-resource-group-name>\
   --endpoint-name <private-endpoint-name> \
   --name "myZoneGroup" \
   --private-dns-zone "privatelink.search.windows.net" \
   --zone-name "searchServiceZone"

For more information on creating private endpoints in Azure CLI, see this Private Link Quickstart.

Manage private endpoint connections

In addition to creating a private endpoint connection, you can also show, update, and delete the connection.

To retrieve a private endpoint connection and to see its status, use az search private-endpoint-connection show.

az search private-endpoint-connection show \
    --name <pe-connection-name> \
    --service-name <search-service-name> \
    --resource-group <search-service-resource-group-name>

To update the connection, use az search private-endpoint-connection update. The following example sets a private endpoint connection to rejected:

az search private-endpoint-connection update \
    --name <pe-connection-name> \
    --service-name <search-service-name> \
    --resource-group <search-service-resource-group-name> 
    --status Rejected \
    --description "Rejected" \
    --actions-required "Please fix XYZ"

To delete the private endpoint connection, use az search private-endpoint-connection delete.

az search private-endpoint-connection delete \
    --name <pe-connection-name> \
    --service-name <search-service-name> \
    --resource-group <search-service-resource-group-name>

Regenerate admin keys

To roll over admin API keys, use az search admin-key renew. Two admin keys are created with each service for authenticated access. Keys are required on every request. Both admin keys are functionally equivalent, granting full write access to a search service with the ability to retrieve any information, or create and delete any object. Two keys exist so that you can use one while replacing the other.

You can only regenerate one at a time, specified as either the primary or secondary key. For uninterrupted service, remember to update all client code to use a secondary key while rolling over the primary key. Avoid changing the keys while operations are in flight.

As you might expect, if you regenerate keys without updating client code, requests using the old key will fail. Regenerating all new keys doesn't permanently lock you out of your service, and you can still access the service through the Azure portal. After you regenerate primary and secondary keys, you can update client code to use the new keys and operations will resume accordingly.

Values for the API keys are generated by the service. You can't provide a custom key for Azure AI Search to use. Similarly, there's no user-defined name for admin API-keys. References to the key are fixed strings, either primary or secondary.

az search admin-key renew \
    --resource-group <search-service-resource-group-name> \
    --service-name <search-service-name> \
    --key-kind primary

Results should look similar to the following output. Both keys are returned even though you only change one at a time.

{
  "primaryKey": <alphanumeric-guid>,
  "secondaryKey": <alphanumeric-guid>  
}

Create or delete query keys

To create query API keys for read-only access from client apps to an Azure AI Search index, use az search query-key create. Query keys are used to authenticate to a specific index for retrieving search results. Query keys don't grant read-only access to other items on the service, such as an index, data source, or indexer.

You can't provide a key for Azure AI Search to use. API keys are generated by the service.

az search query-key create \
    --name myQueryKey \
    --resource-group <search-service-resource-group-name> \
    --service-name <search-service-name>

Scale replicas and partitions

To increase or decrease replicas and partitions use az search service update. Increasing replicas or partitions adds to your bill, which has both fixed and variable charges. If you have a temporary need for more processing power, you can increase replicas and partitions to handle the workload. The monitoring area in the Overview portal page has tiles on query latency, queries per second, and throttling, indicating whether current capacity is adequate.

It can take a while to add or remove resourcing. Adjustments to capacity occur in the background, allowing existing workloads to continue. Extra capacity is used for incoming requests as soon as it's ready, with no extra configuration required.

Removing capacity can be disruptive. Stopping all indexing and indexer jobs prior to reducing capacity is recommended to avoid dropped requests. If that isn't feasible, you might consider reducing capacity incrementally, one replica and partition at a time, until your new target levels are reached.

Once you submit the command, there's no way to terminate it midway through. You have to wait until the command is finished before revising the counts.

az search service update \
    --name <search-service-name> \
    --resource-group <search-service-resource-group-name> \
    --partition-count 6 \
    --replica-count 6

In addition to updating replica and partition counts, you can also update ip-rules, public-access, and identity-type.

Private endpoints of secured resources that are created through Azure AI Search APIs are referred to as shared private link resources. This is because you're "sharing" access to a resource, such as a storage account that has been integrated with the Azure Private Link service.

If you're using an indexer to index data in Azure AI Search, and your data source is on a private network, you can create an outbound private endpoint connection to reach the data.

A full list of the Azure Resources for which you can create outbound private endpoints from Azure AI Search can be found here along with the related Group ID values.

To create the shared private link resource, use az search shared-private-link-resource create. Keep in mind that some configuration might be required for the data source before running this command.

az search shared-private-link-resource create \
    --name <spl-name> \
    --service-name <search-service-name> \
    --resource-group <search-service-resource-group-name> \
    --group-id blob \
    --resource-id "/subscriptions/<alphanumeric-subscription-ID>/resourceGroups/<resource-group-name>/providers/Microsoft.Storage/storageAccounts/myBlobStorage"  \
    --request-message "Please approve"

To retrieve the shared private link resources and view their status, use az search shared-private-link-resource list.

az search shared-private-link-resource list \
    --service-name <search-service-name> \
    --resource-group <search-service-resource-group-name>

You need to approve the connection with the following command before it can be used. The ID of the private endpoint connection must be retrieved from the child resource. In this case, we get the connection ID from az storage.

id = (az storage account show -n myBlobStorage --query "privateEndpointConnections[0].id")

az network private-endpoint-connection approve --id $id

To delete the shared private link resource, use az search shared-private-link-resource delete.

az search shared-private-link-resource delete \
    --name <spl-name> \
    --service-name <search-service-name> \
    --resource-group <search-service-resource-group-name>

For more information on setting up shared private link resources, see making indexer connections through a private endpoint.
