通过Python查看Azure VM的状态

Azure的管理平台采用Restful API的方式实现管理。比如获取VM的管理API的各种操作的文档请参考:

https://docs.microsoft.com/en-us/rest/api/compute/virtualmachines/get

微软发布的各种SDK,PowerShell或CLI都是基于这些API进行的封装,方便操作。

本文将采用Python来获取Azure VM的状态信息。

1 安装Python的Azure模块

Python的Azure模块的Github链接:

https://github.com/gbowerman/azurerm

如果需要管理China的Azure,安装Stan Peng修改过的模块:

pip install mcazurerm

2 创建Azure的Service Principle

Azure的Service Principle就类似一个用户,可以对Azure的资源进行管理。

采用Azure CLI 2.0的具体命令如下:

az ad sp create-for-rbac --name hwsp –password xxxx

获得输出:

{
"appId": "xxxx",
"displayName": "hwsp",
"name": "http://hwsp",
"password": "xxxx",
"tenant": "xxxx"
}

查看:

az role assignment list --assignee xxxx

[
{
"id": "/subscriptions/xxxx/providers/Microsoft.Authorization/roleAssignments/xxxx",
"name": "xxxx",
"properties": {
"principalId": "xxxx",
"principalName": "http://hwsp",
"roleDefinitionId": "/subscriptions/xxxx/providers/Microsoft.Authorization/roleDefinitions/xxxx",
"roleDefinitionName": "Contributor",
"scope": "/subscriptions/xxxx"
},
"type": "Microsoft.Authorization/roleAssignments"
}
]

3 添加创建get_vm_instanceview模块

在原有的mcazurerm中没有查看instanceview的模块,根据前文提到的文档,添加如下:

 

from mcazurerm import *

def get_vm_instanceview(access_token, subscription_id, resource_group, vm_name):
endpoint = ''.join([azure_rm_endpoint,
            '/subscriptions/', subscription_id,
            '/resourceGroups/', resource_group,
            '/providers/Microsoft.Compute/virtualMachines/', vm_name,
            '?$expand=instanceView'
            '&api-version=', COMP_API])
return do_get(endpoint, access_token) 

4 获取Azure VM状态

通过如下代码获取Azure VM状态:

import json
import sys
import mcazurerm
import instanceview

try:
     with open('azurermconfig.json') as config_file:
            config_data = json.load(config_file)
except SystemError:
     sys.exit('Error: Expecting azurermconfig.json in current folder')

tenant_id = config_data['tenantId']
app_id = config_data['appId']
app_secret = config_data['appSecret']
subscription_id = config_data['subscriptionId']

access_token = mcazurerm.get_access_token(tenant_id, app_id, app_secret)

vminstanceview =  instanceview.get_vm_instanceview(access_token,sub['subscriptionId'],"test01","hwcent01")

print 'VM Name: ',vminstanceview['name']
print 'VM Resource Group: ',vminstanceview['id'].split('/')[4]
print 'VM Location: ',vminstanceview['location']
print "VM Status: ",vminstanceview['properties']['instanceView']['statuses'][1]['displayStatus']

Azurermconfig.json的文件格式请参考:

  https://github.com/gbowerman/azurerm/blob/master/examples/azurermconfig.json.tmpl

过具体输出结果如下:

VM Name:  hwcent01
VM Resource Group:  test01
VM Location:  chinanorth
VM Status:  VM deallocated

总结:

Python通过添加模块,实现获取Azure VM运行状态。
