使用python SDK在Azure中创建池

标签: azure azure-sdk azure-sdk-python

我正在尝试基于标准市场ubuntu映像创建一个池。我正在使用Azure 4.0.0image referncevm config reference,其他内容都是基于docs.microsoft.com

编写的

这是我的代码:

import azure.batch as batch
from azure.batch import BatchServiceClient
from azure.batch.batch_auth import SharedKeyCredentials
from azure.batch import models
import sys

account = 'mybatch'
key = 'Acj1hh7vMR6DSodYgYEghjce7mHmfgfdgodYgYEghjce7mHmfgodYgYEghjce7mHmfgCj/7f3Zs1rHdfgPsdlA=='
batch_url = 'https://mybatch.westeurope.batch.azure.com'

creds = SharedKeyCredentials(account, key)
batch_client = BatchServiceClient(creds, base_url = batch_url)


pool_id = 'mypool3'

if batch_client.pool.exists( pool_id ):
  print( 'pool exists' )
  sys.exit()

vmc = models.VirtualMachineConfiguration(
  image_reference = models.ImageReference(
    offer = 'UbuntuServer', 
    publisher = 'Canonical',
    sku = '16.04.0-LTS', 
    version = 'latest', 
    virtual_machine_image_id = None
  ) ,
  node_agent_sku_id = 'batch.node.ubuntu 16.04'
)

pool_config = models.CloudServiceConfiguration(os_family = '5')

new_pool = models.PoolAddParameter(
  id = pool_id, 
  vm_size = 'small', 
  cloud_service_configuration = pool_config, 
  target_dedicated_nodes = 1,
  virtual_machine_configuration = vmc
)

batch_client.pool.add(new_pool)

以下是我从azure门户(添加池JSON编辑器)中获取的一些图像值:

>

  

“ imageReference”:{

     

“发布者”:“规范”,

     

“优惠”:“ UbuntuServer”,

     

“ sku”:“ 16.04.0-LTS”

     

},

但是当我运行代码时,我得到一个错误:

Traceback (most recent call last):
  File "a.py", line 80, in <module>
    batch_client.pool.add(new_pool)
  File "/root/miniconda/lib/python3.6/site-packages/azure/batch/operations/pool_operations.py", line 310, in add
    raise models.BatchErrorException(self._deserialize, response)
azure.batch.models.batch_error_py3.BatchErrorException: {'additional_properties': {}, 'lang': 'en-US', 'value': 'The value provided for one of the properties in the request body is invalid.\nRequestId:d8a1f7fa-6f40-4e4e-8f41-7958egas6efa\nTime:2018-12-05T16:18:44.5453610Z'}

哪些图像值错误?是否可以通过RequestId获得有关此错误的更多信息?


更新

我发现一个newer example here正在使用此助手select_latest_verified_vm_image_with_node_agent_sku来获取图像参考。相同错误The value provided for one of the properties in the request body is invalid.

我对您的代码进行了测试,并得到了相同的错误。然后,我研究并更改代码中的某些内容。而问题则由两件事引起。

第一

pool_config = models.CloudServiceConfiguration(os_family = '5')

您可以查看models.CloudServiceConfiguration的描述:

os_family: The Azure Guest OS family to be installed on the virtual
     machines in the pool. Possible values are: 2 - OS Family 2, equivalent to
     Windows Server 2008 R2 SP1. 3 - OS Family 3, equivalent to Windows Server
     2012. 4 - OS Family 4, equivalent to Windows Server 2012 R2. 5 - OS Family
     5, equivalent to Windows Server 2016. For more information, see Azure
     Guest OS Releases

也许此属性是为Windows设置的。您可以取消此配置。

第二

vm_size = 'small', 

您应将vmSize设置为实际的VM大小。例如, Standard_A1 。参见Choose a VM size for compute nodes in an Azure Batch pool

希望这会对您有所帮助。如果您需要更多帮助,请给我消息。

我认为网上有很多令人困惑的示例,或者它们仅与旧版SDK相匹配。

深入研究我发现的this文档。

  

cloud_service_configuration CloudServiceConfiguration云   池的服务配置。 此属性和   virtualMachineConfiguration是互斥的,并且是其中之一   必须指定属性。如果   创建批次帐户,并将其poolAllocationMode属性设置为   “用户订阅”。

就我而言,我只能使用 cloud_service_configuration = pool_config virtual_machine_configuration = vmc,但不能同时使用。

这是工作代码:

new_pool = models.PoolAddParameter(
  id = pool_id, 
  vm_size = 'BASIC_A1', 
  target_dedicated_nodes = 1,
  virtual_machine_configuration = vmc
)
