Azure NetAppFiles SDK Sample for Python

This project demonstrates how to perform management CRUD operations for Microsoft.NetApp resource provider using Python.

In this sample application we perform the following operations:

  • Creation
    • NetApp Files Account
    • Capacity Pool
    • Volume
    • Snapshot
    • Volume from Snapshot
  • Updates
    • Change a Capacity Pool size from 4TiB to 10TiB
    • Change a Volume size from 100GiB to 1TiB
    • Add a new NFS export policy to an existing volume
  • Deletions
    • Snapshot
    • Volumes
    • Capacity Pools
    • Accounts

If you don't already have a Microsoft Azure subscription, you can get a FREE trial account here.


  1. Python (code was built and tested under 3.9.5 version)
  2. Azure Subscription
  3. Subscription needs to have Azure NetApp Files resource provider registered. For more information, see Register for NetApp Resource Provider.
  4. Resource Group created
  5. Virtual Network with a delegated subnet to Microsoft.Netapp/volumes resource. For more information, please refer to Guidelines for Azure NetApp Files network planning
  6. For this sample Python console application work, we need to authenticate and the chosen method for this sample is using service principals.
    1. Within an Azure Cloud Shell session, make sure you're logged on at the subscription where you want to be associated with the service principal by default: bash az account show If this is not the correct subscription, use
      bash az account set -s <subscription name or id>

      1. Create a service principal using Azure CLI

        az ad sp create-for-rbac --sdk-auth

        Note: this command will automatically assign RBAC contributor role to the service principal at subscription level, you can narrow down the scope to the specific resource group where your tests will create the resources.

      2. Copy the output content and paste it in a file called azureauth.json and secure it with file system permissions

      3. Set an environment variable pointing to the file path you just created, here is an example with Powershell and bash: Powershell

        [Environment]::SetEnvironmentVariable("AZURE_AUTH_LOCATION", "C:\sdksample\azureauth.json", "User")


        export AZURE_AUTH_LOCATION=/sdksamples/azureauth.json

      Note: for other Azure Active Directory authentication methods for Python, please refer to these samples.

What is doing?

Currently, Azure NetApp Files SDK exposes control plane management operations, CRUD operations for its resources like accounts, capacity pools, volumes and snapshots. We start this execution by defining some basic variables that will be used throughout the code to define resource group name, location, account name, etc.

Note: Please refer to Resource limits for Azure NetApp Files to understand ANF's most current limits.

Next, it will move forward to the authentication process, this sample uses ClientSecretCredential (service principal based authentication) which is accepted by NetAppManagementClient to create the management client, that is extensively used throughout the code.

Then, it will start the CRUD operations by creating one account, then capacity pool, volume, snapshot and volume from snapshot, in this exact sequence (for more information about Azure NetApp Files storage hierarchy please refer to this document). After all resources are created, it will perform an update to a capacity pool by increasing its size; it will perform updates to a volume by changing its usage threshold (size) and adding an extra export policy.

Finally, the clean up process takes place (not enabled by default, please change variable SHOULD_CLEANUP to True if you want clean up to take place), deleting all resources in the reverse order following the hierarchy otherwise we can't remove resources that have nested resources still live. You will also notice that the clean up process uses a function called wait_for_anf_resource, at this moment this is required so we can workaround a current ARM behavior of reporting that the object was deleted when in fact its deletion is still in progress. We will also notice some functions called get_anf_<resource type>, these were also created in this sample to be able to get the name of the resource without its hierarchy represented in the <resource type>.name property, which cannot be used directly in other methods of Azure NetApp Files client like get.

How to run the script

  1. Clone it locally
    git clone
  2. Change folder to .\netappfiles-python-sdk-sample\src
  3. Install any missing dependencies as needed
    pip install -r ./requirements.txt
  4. Make sure you have the azureauth.json and its environment variable with the path to it defined (as previously described at prerequisites)
  5. Edit file and change the variables contents as appropriate (names are self-explanatory).
  6. Run the script
    python ./
