Python Azure函数在本地运行，但不'；在Docker容器构建并在本地运行之后，不要做任何事情

我有一个Azure函数，带有自定义导入的python模块，当我在目录中使用

func start

时，它可以正确运行。但是，下一步是让它在

Docker

容器中本地运行。在构建并运行（）之后，什么也没有发生，我得到以下输出：

我使用

docker build--tag/azurefunctionsimage:v1.0.0.

构建映像，然后从docker桌面单击“运行”运行它

我一直在密切关注如何让硒在容器中工作。我已经将我的刮片功能指向了

chromedriver

，但我认为这不是问题所在。这是我的

function.json

文件：

{
  "scriptFile": "__init__.py",
  "bindings": [
    {
      "name": "mytimer",
      "type": "timerTrigger",
      "direction": "in",
      "schedule": "0 * * * * *"
    }
  ]
}

{
  "IsEncrypted": false,
  "Values": {
    "FUNCTIONS_WORKER_RUNTIME": "python",
    "AzureWebJobsStorage": "UseDevelopmentStorage=true;"
  }
}

和

local.settings.json

文件：

{
  "scriptFile": "__init__.py",
  "bindings": [
    {
      "name": "mytimer",
      "type": "timerTrigger",
      "direction": "in",
      "schedule": "0 * * * * *"
    }
  ]
}

{
  "IsEncrypted": false,
  "Values": {
    "FUNCTIONS_WORKER_RUNTIME": "python",
    "AzureWebJobsStorage": "UseDevelopmentStorage=true;"
  }
}

VSCode中的文件结构：

FunctionDirectory
    |_ BadFunc
        | __init__.py
        | custom_mod1.py
        | custom_mod2.py
          ...
        | function.json
    |_ local.settings.json
       Dockerfile
       requirements.txt
       etc..

在本地运行容器时，我是否遗漏了一些明显的原因，即为什么没有得到任何结果

或者这与实际的

\uuu init\uuuu.py

代码有关，返回类型为

None

，而不是其他类型

def main(mytimer: func.TimerRequest) -> None: #should be something else?
    utc_timestamp = datetime.datetime.utcnow().replace(
        tzinfo=datetime.timezone.utc).isoformat()

    if mytimer.past_due:
        logging.info('The timer is past due!')

    logging.info('Python timer trigger function ran at %s', utc_timestamp)
    
    # Class instantiation for the handling stuff ----
    name_handle_instance = dc.NameHandle()
    #calls other functions below...

您有为连接字符串设置的值吗？@Sajeetharan-除非您谈论的是

本地.settings.json

中的

AzureWebJobsStorage:“UseDevelopmentStorage=true；”“

，否则没有。在哪里可以这样做？谢谢你能像复制粘贴我Azure存储帐户中的连接字符串一样复制粘贴连接字符串吗？可以！对的试着替换
