运行我的 docker 映像时无法解析名为“AzureWebJobsStorage”的 Azure 存储连接

问题描述 投票：0回答：1

我有一个使用azure持久功能的应用程序，它在本地运行得很好，但是当我容器化这个应用程序并运行我的图像时，我收到此错误：无法解析名为“AzureWebJobsStorage”的Azure存储连接。

这是我测试过的：

  • 我在我的 local.settings.json 文件中设置了“AzureWebJobsStorage”：“DefaultEndpointsProtocol=https;AccountName=...”。
  • 我在 azure 应用程序设置中设置了“AzureWebJobsStorage”和“AzureWebJobsDashboard”，其连接字符串与 local.settings.json 文件相同。
  • 我将其添加到 host.json 文件中：
  "extensions": {
    "durableTask": {
      "hubName": "MyTaskHub",
      "storageProvider": {
        "connectionStringName": "AzureWebJobsStorage"
      }
    }
  },
  • 我检查了我提到的两个 JSON 文件中的缩进和逗号，一切看起来都很好。
  • 我重新启动了函数应用程序。
  • 我读过几个论坛和文章，但解决方案总是相同的（我提到的）。

但是没有任何效果:( 非常感谢您的帮助，谢谢！

当我尝试运行容器化Python Azure Durable函数时，我遇到了同样的错误。

  • 要解决此错误，请将存储连接字符串作为名为 
    AzureWebJobsStorage
    的环境变量传递给 
    docker run
    命令。
docker run -p 8080:80 -it -e AzureWebJobsStorage="<Storage_connection_string>" <Image_name>:tag

或将 

Storage_account
设置为 ARG 并将其作为 Docker 文件中的环境变量传递。

Dockerfile：

FROM mcr.microsoft.com/azure-functions/python:4-python3.11

ARG STORAGE_ACCOUNT
ENV AzureWebJobsScriptRoot=/home/site/wwwroot \
AzureFunctionsJobHost__Logging__Console__IsEnabled=true \
AzureWebJobsStorage=$STORAGE_ACCOUNT

COPY requirements.txt /
RUN pip install -r /requirements.txt

COPY . /home/site/wwwroot
  • 运行图像的命令：
1. docker build --build-arg STORAGE_ACCOUNT='<storage_connection_string>' -t <Image_name> .
2. docker run -p 8080:80 <Image_name>

使用 docker 创建了一个 python 持久函数：

func init --docker
func new

local.settings.json：

{
  "IsEncrypted": false,
  "Values": {
    "AzureWebJobsStorage": "UseDevelopmentStorage=true",
    "FUNCTIONS_WORKER_RUNTIME": "python",
    "AzureWebJobsFeatureFlags": "EnableWorkerIndexing"
  }
}
  • 能够成功运行docker镜像：
(.venv) C:\Users\uname\pydf>docker run -p 8080:80 -it -e AzureWebJobsStorage="<Storage_connection_string>" pravallikakv/pydf
