Azure KeyVault Administration client library for Python
=======================================================
Azure Key Vault helps solve the following problems:
* Vault administration (this library) - role-based access control (RBAC), and vault-level backup and restore options
* Cryptographic key management (\ `azure-keyvault-keys `_\ ) - create, store, and control
access to the keys used to encrypt your data
* Secrets management
(\ `azure-keyvault-secrets `_\ ) -
securely store and control access to tokens, passwords, certificates, API keys,
and other secrets
* Certificate management
(\ `azure-keyvault-certificates `_\ ) -
create, manage, and deploy public and private SSL/TLS certificates
Getting started
---------------
Install packages
^^^^^^^^^^^^^^^^
Install `azure-keyvault-administration `_ and
`azure-identity `_ with `pip `_\ :
.. code-block:: Bash
pip install azure-keyvault-administration azure-identity
`azure-identity `_ is used for Azure Active Directory
authentication as demonstrated below.
Prerequisites
^^^^^^^^^^^^^
* An `Azure subscription `_
* Python 2.7, 3.5.3, or later
* A Key Vault. If you need to create one, See the final two steps in the next section for details on creating the Key Vault with the Azure CLI.
Authenticate the client
^^^^^^^^^^^^^^^^^^^^^^^
This document demonstrates using `DefaultAzureCredential `_
to authenticate as a service principal. However, this package's clients
accept any `azure-identity `_ credential. See the
`azure-identity `_ documentation for more information about other
credentials.
Create and Get credentials
~~~~~~~~~~~~~~~~~~~~~~~~~~
This `Azure Cloud Shell `_ snippet shows how to create a
new service principal. Before using it, replace "your-application-name" with
a more appropriate name for your service principal.
*
Create a service principal:
.. code-block:: Bash
az ad sp create-for-rbac --name http://your-application-name --skip-assignment
..
Output:
.. code-block:: json
{
"appId": "generated app id",
"displayName": "your-application-name",
"name": "http://your-application-name",
"password": "random password",
"tenant": "tenant id"
}
*
Take note of the service principal objectId
.. code-block:: Bash
az ad sp show --id --query objectId
.. code-block::
> Output:
> ```
> ""
> ```
*
Use the output to set **AZURE_CLIENT_ID** ("appId" above), **AZURE_CLIENT_SECRET**
("password" above) and **AZURE_TENANT_ID** ("tenant" above) environment variables.
The following example shows a way to do this in Bash:
.. code-block:: Bash
export AZURE_CLIENT_ID="generated app id"
export AZURE_CLIENT_SECRET="random password"
export AZURE_TENANT_ID="tenant id"
*
Create the Key Vault and grant the above mentioned application authorization to perform administrative operations on the Azure Key Vault (replace ```` and ```` with your own, unique names and ```` with the value from above):
.. code-block:: Bash
az keyvault create --hsm-name --resource-group --administrators --location
*
Use the above mentioned Azure Key Vault name to retrieve details of your Vault which also contains your Azure Key Vault URL:
.. code-block:: Bash
az keyvault show --hsm-name
Create a client
~~~~~~~~~~~~~~~
Once the **AZURE_CLIENT_ID**\ , **AZURE_CLIENT_SECRET** and
**AZURE_TENANT_ID** environment variables are set,
`DefaultAzureCredential `_ will be able to authenticate the
clients.
There are two clients available in this package, below are snippets demonstrating how to construct
each one of these clients. Constructing a client also requires your vault's URL, which you can
get from the Azure CLI or the Azure Portal. In the Azure Portal, this URL is
the vault's "DNS Name".
Create a KeyVaultAccessControlClient
""""""""""""""""""""""""""""""""""""
.. code-block:: python
from azure.identity import DefaultAzureCredential
from azure.keyvault.administration import KeyVaultAccessControlClient
credential = DefaultAzureCredential()
client = KeyVaultAccessControlClient(vault_url="https://my-key-vault.vault.azure.net/", credential=credential)
Create a KeyVaultBackupClient
"""""""""""""""""""""""""""""
.. code-block:: python
from azure.identity import DefaultAzureCredential
from azure.keyvault.administration import KeyVaultBackupClient
credential = DefaultAzureCredential()
client = KeyVaultBackupClient(vault_url="https://my-key-vault.vault.azure.net/", credential=credential)
Key concepts
------------
Role Definition
^^^^^^^^^^^^^^^
A role definition defines the operations that can be performed, such as read, write, and delete. It can also define the operations that are excluded from allowed operations.
A role definition is specified as part of a role assignment.
Role Assignment.
^^^^^^^^^^^^^^^^
A role assignment is the association of a role definition to a service principal. They can be created, listed, fetched individually, and deleted.
KeyVaultAccessControlClient
^^^^^^^^^^^^^^^^^^^^^^^^^^^
A ``KeyVaultAccessControlClient`` manages role definitions and role assignments.
KeyVaultBackupClient
^^^^^^^^^^^^^^^^^^^^
A ``KeyVaultBackupClient`` performs full key backups, full key restores, and selective key restores.
Examples
--------
This section conntains code snippets covering common tasks:
* Access Control
* :raw-html-m2r:`List all role definitions`
* :raw-html-m2r:`List all role assignments`
* :raw-html-m2r:`Create, Get, and Delete a role assignment`
* Backup and Restore
* :raw-html-m2r:`Perform a full key backup`
* :raw-html-m2r:`Perform a full key restore`
List all role definitions
^^^^^^^^^^^^^^^^^^^^^^^^^
List the role definitions available for assignment.
.. code-block:: python
from azure.identity import DefaultAzureCredential
from azure.keyvault.administration import KeyVaultAccessControlClient, KeyVaultRoleScope
credential = DefaultAzureCredential()
client = KeyVaultAccessControlClient(vault_url="https://my-key-vault.vault.azure.net/", credential=credential)
# this is the global scope. This will list all role definitions available for assignment
role_definitions = client.list_role_definitions(role_scope=KeyVaultRoleScope.global_value)
for role_definition in role_definitions:
print(role_definition.id)
print(role_definition.role_name)
print(role_definition.description)
List all role assignments
^^^^^^^^^^^^^^^^^^^^^^^^^
Before creating a new role assignment in the `next snippet <#create-get-and-delete-a-role-assignment>`_\ , list all of the current role assignments
.. code-block:: python
from azure.identity import DefaultAzureCredential
from azure.keyvault.administration import KeyVaultAccessControlClient, KeyVaultRoleScope
credential = DefaultAzureCredential()
client = KeyVaultAccessControlClient(vault_url="https://my-key-vault.vault.azure.net/", credential=credential)
# this is the global scope. This will list all role assignments available for assignment
role_assignments = client.list_role_assignments(role_scope=KeyVaultRoleScope.global_value)
for role_assignment in role_assignments:
print(role_assignment.name)
print(role_assignment.principal_id)
print(role_assignment.role_definition_id)
Create, Get, and Delete a role assignment
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
Assign a role to a service principal. This will require a role definition id from the list retrieved in the `above snippet <#list-all-role-definitions>`_ and the principal object id retrieved in the `Create and Get credentials <#create-and-get-credentials>`_
.. code-block:: python
import uuid
from azure.identity import DefaultAzureCredential
from azure.keyvault.administration import KeyVaultAccessControlClient
credential = DefaultAzureCredential()
client = KeyVaultAccessControlClient(vault_url="https://my-key-vault.vault.azure.net/", credential=credential)
role_scope = "/" # setting the scope to the global scope
role_assignment_name = uuid.uuid4()
role_definition_id = "" # Replace with the id of a definition returned from the previous example
principal_id = ""
# first, let's create the role assignment
role_assignment = client.create_role_assignment(role_scope, role_assignment_name, role_definition_id, principal_id)
print(role_assignment.name)
print(role_assignment.principal_id)
print(role_assignment.role_definition_id)
# now, we get it
role_assignment = client.get_role_assignment(role_scope, role_assignment.name)
print(role_assignment.name)
print(role_assignment.principal_id)
print(role_assignment.role_definition_id)
# finally, we delete this role assignment
role_assignment = client.delete_role_assignment(role_scope, role_assignment.name)
print(role_assignment.name)
print(role_assignment.principal_id)
print(role_assignment.role_definition_id)
Perform a full key backup
^^^^^^^^^^^^^^^^^^^^^^^^^
Back up your entire collection of keys. The backing store for full key backups is a blob storage container using Shared Access Signature authentication.
For more details on creating a SAS token using the ``BlobServiceClient``\ , see the sample `here `_.
Alternatively, it is possible to `generate a SAS token in Storage Explorer `_
.. code-block:: python
from azure.identity import DefaultAzureCredential
from azure.keyvault.administration import KeyVaultBackupClient
credential = DefaultAzureCredential()
client = KeyVaultBackupClient(vault_url="https://my-key-vault.vault.azure.net/", credential=credential)
blob_storage_uri = "" # the URI to your storage account. Should contain the name of the specific container
sas_token = "" # replace with the sas token to your storage account. See this snippet's description on help to retrieve
# performing a full key backup is a long-running operation. Calling `result()` on the poller will wait
# until the backup is completed, then return an object representing the backup operation.
backup_operation = client.begin_full_backup(blob_storage_uri, sas_token).result()
# this is the URI of the Azure blob storage container which contains the backup
azure_storage_blob_container_uri = backup_operation.azure_storage_blob_container_uri
print(backup_operation.status)
print(backup_operation.job_id)
print(azure_storage_blob_container_uri)
Perform a full key restore
^^^^^^^^^^^^^^^^^^^^^^^^^^
Restore your entire collection of keys from a backup. The data source for a full key restore is a storage blob accessed using Shared Access Signature authentication.
You will also need the ``azure_storage_blob_container_uri`` from the `above snippet <#perform-a-full-key-backup>`_.
For more details on creating a SAS token using the ``BlobServiceClient``\ , see the sample `here `_.
Alternatively, it is possible to `generate a SAS token in Storage Explorer `_
.. code-block:: python
from azure.identity import DefaultAzureCredential
from azure.keyvault.administration import KeyVaultBackupClient
credential = DefaultAzureCredential()
client = KeyVaultBackupClient(vault_url="https://my-key-vault.vault.azure.net/", credential=credential)
blob_storage_uri = "" # the URI to your storage account. Should contain the name of the specific container
sas_token = "" # replace with the sas token to your storage account. See this snippet's description on help to retrieve
# Replace with the blob storage container returned in the previous example
azure_storage_blob_container_uri = ""
folder_name = azure_storage_blob_container_uri.split("/")[-1]
# performing a full key restore is a long-running operation. Calling `result()` on the poller will wait
# until the restore is completed, then return an object representing the restore operation.
restore_operation = client.begin_full_restore(blob_storage_uri, sas_token, folder_name).result()
print(restore_operation.status)
print(restore_operation.job_id)
Troubleshooting
---------------
General
^^^^^^^
Key Vault clients raise exceptions defined in `azure-core `_.
For example, if you try to get a role assignment that doesn't exist, KeyVaultAccessControlClient
raises `ResourceNotFoundError `_\ :
.. code-block:: python
from azure.identity import DefaultAzureCredential
from azure.keyvault.administration import KeyVaultAccessControlClient
from azure.core.exceptions import ResourceNotFoundError
credential = DefaultAzureCredential()
client = KeyVaultAccessControlClient(vault_url="https://my-key-vault.vault.azure.net/", credential=credential)
try:
client.get_role_assignment("/", "which-does-not-exist")
except ResourceNotFoundError as e:
print(e.message)
