在Azure Batch中使用托管标识在批处理池中使用Python对密钥库进行身份验证

Question

from azure.keyvault import KeyVaultClient
from msrestazure.azure_active_directory import MSIAuthentication

credentials = MSIAuthentication(resource='https://vault.azure.net')

kvclient = KeyVaultClient(credentials)
res = kvclient.get_secret("https://kv.vault.azure.net/", "secret", "").value

对于较新的azure keyvault包，我使用了以下内容：

import os
import cmd
from azure.keyvault.secrets import SecretClient
from azure.identity import ManagedIdentityCredential

keyVaultName = "kv"
KVUri = f"https://{keyVaultName}.vault.azure.net"

credential = DefaultAzureCredential()
client = SecretClient(vault_url=KVUri, credential=credential)

secretName = "secret"
retrieved_secret = client.get_secret(secretName)

但是它找不到ManagedIdentityCredential。这是错误的一部分：

SharedTokenCacheCredential.get_token failed: Shared token cache unavailable
VisualStudioCodeCredential.get_token failed: Failed to get Azure user details from Visual Studio Code.
AzureCliCredential.get_token failed: Please run 'az login' to set up an account
DefaultAzureCredential failed to retrieve a token from the included credentials.
Attempted credentials:
    EnvironmentCredential: EnvironmentCredential authentication unavailable. Environment variables are not fully configured.
    ManagedIdentityCredential: ManagedIdentityCredential authentication unavailable. No identity has been assigned to this resource.
    SharedTokenCacheCredential: Shared token cache unavailable
    VisualStudioCodeCredential: Failed to get Azure user details from Visual Studio Code.
    AzureCliCredential: Please run 'az login' to set up an account
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
