Develop for Azure NetApp Files with REST API

  • Bài viết

The REST API for the Azure NetApp Files service defines HTTP operations against resources such as the NetApp account, the capacity pool, the volumes, and snapshots. This article helps you get started with using the Azure NetApp Files REST API.

Azure NetApp Files REST API specification

The REST API specification for Azure NetApp Files is published through GitHub:

https://github.com/Azure/azure-rest-api-specs/tree/main/specification/netapp/resource-manager

Considerations

  • When the API limit has been exceeded, the HTTP response code is 429. For example:

    "Microsoft.Azure.ResourceProvider.Common.Exceptions.ResourceProviderException: Error getting Pool. Rate limit exceeded for this endpoint - try again later ---> CloudVolumes.Service.Client.Client.ApiException: Error calling V2DescribePool: {\"code\":429,\"message\":\"Rate limit exceeded for this endpoint - try again later\"}

    This response code can come from throttling or a temporary condition. See Azure Resource Manager HTTP 429 response code for more information.

Access the Azure NetApp Files REST API

  1. Install the Azure CLI if you haven't done so already.

  2. Create a service principal in your Microsoft Entra ID:

    1. Verify that you have sufficient permissions.

    2. Enter the following command in the Azure CLI:

      Azure CLI 
      az ad sp create-for-rbac --name $YOURSPNAMEGOESHERE --role Contributor --scopes /subscriptions/{subscription-id}

      The command output is similar to the following example:

      Output 
      { 
    "appId": "appIDgoeshere", 
    "displayName": "APPNAME", 
    "name": "http://APPNAME", 
    "password": "supersecretpassword", 
    "tenant": "tenantIDgoeshere" 
}

      Keep the command output. You will need the appId, password, and tenant values.

  3. Request an OAuth access token:

    The examples in this article use cURL. You can also use various API tools such as Postman, Insomnia, and Paw.

    Replace the variables in the following example with the command output from Step 2 above.

    Azure CLI 
    curl -X POST -d 'grant_type=client_credentials&client_id=[APP_ID]&client_secret=[PASSWORD]&resource=https%3A%2F%2Fmanagement.azure.com%2F' https://login.microsoftonline.com/[TENANT_ID]/oauth2/token

    The output provides an access token similar to the following example:

    eyJ0eXAiOiJKV1QiLCJhbGciOiJSUzI1NiIsIng1dCI6Im5iQ3dXMTF3M1hrQi14VWFYd0tSU0xqTUhHUSIsImtpZCI6Im5iQ3dXMTF3M1hrQi14VWFYd0tSU0xqTUhHUSJ9

    The displayed token is valid for 3600 seconds. After that, you need to request a new token. Save the token to a text editor. You will need it for the next step.

  4. Send a test call and include the token to validate your access to the REST API:

    Azure CLI 
    curl -X GET -H "Authorization: Bearer [TOKEN]" -H "Content-Type: application/json" https://management.azure.com/subscriptions/[SUBSCRIPTION_ID]/providers/Microsoft.Web/sites?api-version=2022-05-01

Examples using the API

This article uses the following URL for the baseline of requests. This URL points to the root of the Azure NetApp Files namespace.

https://management.azure.com/subscriptions/SUBIDGOESHERE/resourceGroups/RESOURCEGROUPGOESHERE/providers/Microsoft.NetApp/netAppAccounts?api-version=2022-05-01

You should replace the SUBIDGOESHERE and RESOURCEGROUPGOESHERE values in the following examples with your own values.

GET request examples

You use a GET request to query objects of Azure NetApp Files in a subscription, as the following examples show:

Azure CLI 
#get NetApp accounts 
curl -X GET -H "Authorization: Bearer TOKENGOESHERE" -H "Content-Type: application/json" https://management.azure.com/subscriptions/SUBIDGOESHERE/resourceGroups/RESOURCEGROUPGOESHERE/providers/Microsoft.NetApp/netAppAccounts?api-version=2022-05-01
Azure CLI 
#get capacity pools for NetApp account 
curl -X GET -H "Authorization: Bearer TOKENGOESHERE" -H "Content-Type: application/json" https://management.azure.com/subscriptions/SUBIDGOESHERE/resourceGroups/RESOURCEGROUPGOESHERE/providers/Microsoft.NetApp/netAppAccounts/NETAPPACCOUNTGOESHERE/capacityPools?api-version=2022-05-01
Azure CLI 
#get volumes in NetApp account & capacity pool 
curl -X GET -H "Authorization: Bearer TOKENGOESHERE" -H "Content-Type: application/json" https://management.azure.com/subscriptions/SUBIDGOESHERE/resourceGroups/RESOURCEGROUPGOESHERE/providers/Microsoft.NetApp/netAppAccounts/NETAPPACCOUNTGOESHERE/capacityPools/CAPACITYPOOLGOESHERE/volumes?api-version=2022-05-01
Azure CLI 
#get snapshots for a volume 
curl -X GET -H "Authorization: Bearer TOKENGOESHERE" -H "Content-Type: application/json" https://management.azure.com/subscriptions/SUBIDGOESHERE/resourceGroups/RESOURCEGROUPGOESHERE/providers/Microsoft.NetApp/netAppAccounts/NETAPPACCOUNTGOESHERE/capacityPools/CAPACITYPOOLGOESHERE/volumes/VOLUMEGOESHERE/snapshots?api-version=2022-05-01

PUT request examples

You use a PUT request to create new objects in Azure NetApp Files, as the following examples show. The body of the PUT request can include the JSON formatted data for the changes. It must be included in the curl command as text or references as a file. To reference the body as a file, save the json example to a file and add -d @<filename> to the curl command.

Azure CLI 
#create a NetApp account  
curl -d @<filename> -X PUT -H "Authorization: Bearer TOKENGOESHERE" -H "Content-Type: application/json" https://management.azure.com/subscriptions/SUBIDGOESHERE/resourceGroups/RESOURCEGROUPGOESHERE/providers/Microsoft.NetApp/netAppAccounts/NETAPPACCOUNTGOESHERE?api-version=2022-05-01
Azure CLI 
#create a capacity pool  
curl -d @<filename> -X PUT -H "Authorization: Bearer TOKENGOESHERE" -H "Content-Type: application/json" https://management.azure.com/subscriptions/SUBIDGOESHERE/resourceGroups/RESOURCEGROUPGOESHERE/providers/Microsoft.NetApp/netAppAccounts/NETAPPACCOUNTGOESHERE/capacityPools/CAPACITYPOOLGOESHERE?api-version=2022-05-01
Azure CLI 
#create a volume  
curl -d @<filename> -X PUT -H "Authorization: Bearer TOKENGOESHERE" -H "Content-Type: application/json" https://management.azure.com/subscriptions/SUBIDGOESHERE/resourceGroups/RESOURCEGROUPGOESHERE/providers/Microsoft.NetApp/netAppAccounts/NETAPPACCOUNTGOESHERE/capacityPools/CAPACITYPOOLGOESHERE/volumes/MYNEWVOLUME?api-version=2022-05-01
Azure CLI 
 #create a volume snapshot  
curl -d @<filename> -X PUT -H "Authorization: Bearer TOKENGOESHERE" -H "Content-Type: application/json" https://management.azure.com/subscriptions/SUBIDGOESHERE/resourceGroups/RESOURCEGROUPGOESHERE/providers/Microsoft.NetApp/netAppAccounts/NETAPPACCOUNTGOESHERE/capacityPools/CAPACITYPOOLGOESHERE/volumes/MYNEWVOLUME/Snapshots/SNAPNAME?api-version=2022-05-01

JSON examples

The following example shows how to create a NetApp account:

JSON 
{ 
    "name": "MYNETAPPACCOUNT", 
    "type": "Microsoft.NetApp/netAppAccounts", 
    "location": "westus2", 
    "properties": { 
        "name": "MYNETAPPACCOUNT" 
    }
}

The following example shows how to create a capacity pool:

JSON 
{
    "name": "MYNETAPPACCOUNT/POOLNAME",
    "type": "Microsoft.NetApp/netAppAccounts/capacityPools",
    "location": "westus2",
    "properties": {
        "name": "POOLNAME",
        "size": "4398046511104",
        "serviceLevel": "Premium"
    }
}

The following example shows how to create a new volume. (The default protocol for the volume is NFSV3.)

JSON 
{
    "name": "MYNEWVOLUME",
    "type": "Microsoft.NetApp/netAppAccounts/capacityPools/volumes",
    "location": "westus2",
    "properties": {
        "serviceLevel": "Premium",
        "usageThreshold": "322122547200",
        "creationToken": "MY-FILEPATH",
        "snapshotId": "",
        "subnetId": "/subscriptions/SUBIDGOESHERE/resourceGroups/RESOURCEGROUPGOESHERE/providers/Microsoft.Network/virtualNetworks/VNETGOESHERE/subnets/MYDELEGATEDSUBNET.sn"
         }
}

The following example shows how to create a snapshot of a volume:

JSON 
{
    "name": "apitest2/apiPool01/apiVol01/snap02",
    "type": "Microsoft.NetApp/netAppAccounts/capacityPools/Volumes/Snapshots",
    "location": "westus2",
    "properties": {
         "name": "snap02",
        "fileSystemId": "0168704a-bbec-da81-2c29-503825fe7420"
    }
}

Lưu ý

You need to specify fileSystemId for creating a snapshot. You can obtain the fileSystemId value with a GET request to a volume.
