Azure 函数 - 触发包含 Azure CLI 命令的 Python 脚本
问题描述
我有一个用于在 Azure - IaC 中配置基础架构的 Python 脚本.此脚本主要使用 Python SDK，但也运行多个 Azure CLI 命令 - 当我在 Python SDK 中找不到等效命令时，有时需要它.
I have a python script for provisioning infrastructure in Azure - IaC. This script is using mostly the Python SDK, but is also running multiple Azure CLI commands - it is needed at times when I didn't find an equivalent command in the Python SDK.
我的目标是使用 Azure Functions 按需触发此脚本.在本地测试 Azure 函数时，一切正常，因为我在我的机器上安装了 Azure CLI，但是，当我将它发布到 Azure 函数时，我会遇到一个错误:/bin/sh: 1: az:没找到
My goal is to trigger this script on-demand using Azure Functions. When testing the Azure Function locally, everything works fine as I have Azure CLI installed on my machine, however, when I publish it to Azure functions, I will run into an error that: /bin/sh: 1: az: not found
下面是我在 Azure 函数中触发的示例 python 函数(请注意，脚本的其余部分工作正常，所以我可以创建 RG、SQL 服务器等，问题只是 az 命令).我想知道，我是否以及如何在 Azure Function 上安装 Azure CLI 以便能够运行 CLI 命令?
Below is the sample python function I trigger in the Azure Function (Please note that the rest of script works fine, so I can create RG, SQL server etc, the problem is just the az commands). I wonder, if and how could I install Azure CLI on the Azure Function in order to be able to run the CLI commands?
这是导致错误的python函数:
Here is the python function causing the error:
# Loging to AZ
call("az login --service-principal -u '%s' -p '%s' --tenant '%s'" % (client_id, client_secret, tenant_id), shell=True)
b2c_id = check_output("az resource show -g '<rg_name>' -n '<b2c_name>' --resource-type 'Microsoft.AzureActiveDirectory/b2cDirectories' --query id --output tsv", shell=True)
print("The B2C ID is: %s" % b2c_id)```
解决方案
我尝试使用 HttpTrigger 创建一个简单的 Azure Function 以通过不同方式调用 Azure CLI 工具，但发布后无法在云上运行.
I tried to create a simple Azure Function with HttpTrigger to invoke Azure CLI tools by different ways, but never works on cloud after published.
似乎唯一的解决方案是使用 --build-native-deps 命令选项将函数发布为 docker 映像 func azure functionapp publish <your function app name> 将需要的包azure-cli 添加到requirements.txt 文件后，如下图错误所示，
It seems the only solution is to publish the function as docker image with --build-native-deps option for the command func azure functionapp publish <your function app name> after add the required package azure-cli into the requirements.txt file, as the figure with error below said,
恢复依赖时出错.错误:无法安装 antlr4-python3-runtime-4.7.2 依赖:不支持没有轮子的二进制依赖.使用 --build-native-deps 选项使用 Docker 容器自动构建和配置依赖项. 更多信息请访问 https://aka.ms/func-python-publish
There was an error restoring dependencies.ERROR: cannot install antlr4-python3-runtime-4.7.2 dependency: binary dependencies without wheels are not supported. Use the --build-native-deps option to automatically build and configure the dependencies using a Docker container. More information at https://aka.ms/func-python-publish
由于我本地没有 docker 工具，我没有成功运行 func azure functionapp publish <your function app name>--build-native-deps.
Due to there is not docker tools in my local, I did not successfully run func azure functionapp publish <your function app name> --build-native-deps.
同时，运行 Azure CLI 命令并不是使用 Azure CLI 功能的唯一方法.az 命令只是一个可运行的脚本文件，而不是二进制执行文件.在我查看了 az 和 azure-cli 包的一些源代码后，我认为您可以直接通过 from azure.cli.core import get_default_cli 并使用它来执行与下面的代码相同的操作.
Meanwhile, running Azure CLI commands is not the only one ways to use the functions of Azure CLI. The az command is just a runnable script file, not a binary execute file. After I reviewd az and some source codes of azure-cli package, I think you can directly import the package via from azure.cli.core import get_default_cli and to use it to do the same operations like the code below.
from azure.cli.core import get_default_cli
az_cli = get_default_cli()
exit_code = az_cli.invoke(args)
sys.exit(exit_code)
代码是参考azure-cli包的azure/cli/__main__.py源码编写的，可以从中看到lib/python3.x/site-packages 你的虚拟环境的路径.
The code is written by referring to the source code of azure/cli/__main__.py of azure-cli package, you can see it from the lib/python3.x/site-packages path of your virtual environment.
希望对你有帮助.
