Asp.net Docker 中的 ASPNETCORE_ENVIRONMENT

我无法设置在docker container中运行项目的ASPNETCORE_ENVIRONMENT变量.问题是这个值总是set/overwritten to "Development".

我已经try 过在我的Dockerfile中设置环境变量

ENV ASPNETCORE_ENVIRONMENT test

我还try 使用以下命令设置我的docker-compose文件中的环境变量

environment:
      - ASPNETCORE_ENVIRONMENT=test

当我将任何其他环境变量设置为it works时，例如:

environment:
      - OTHER_TEST_VARIABLE=test

我假设ASPNETCORE_ENVIRONMENT变量的值在某个地方被覆盖了，但我很难找到在哪里.

我已经将Docker支持添加到一个现有项目中，并通过Visual Studio的Docker/Docker compose选项直接运行该项目

该项目在Asp Net Core 2.1上运行

提前谢谢你

我的启动设置.json:

{
  "iisSettings": {
    "windowsAuthentication": false,
    "anonymousAuthentication": true,
    "iisExpress": {
      "applicationUrl": "http://localhost:53183/",
      "sslPort": 0
    }
  },
  "profiles": {

    "Docker": {
      "commandName": "Docker",
      "launchBrowser": true,
      "launchUrl": "{Scheme}://localhost:{ServicePort}/api/values"

    }

  }
}

我还try 将环境变量配置添加到LaunchSettings.json文件中

"Docker": {
          "commandName": "Docker",
          "launchBrowser": true,
          "launchUrl": "{Scheme}://localhost:{ServicePort}/api/values",
          "environmentVariables": {
           "ASPNETCORE_ENVIRONMENT": "test"
      }
        }

 public static IWebHost BuildWebHost(string[] args)
        {
           return WebHost.CreateDefaultBuilder(args)
                .ConfigureAppConfiguration((builderContext,config) =>
                {
                    config.AddEnvironmentVariables();
                })
                .ConfigureLogging((hostingContext, logging) =>
                {
                    logging.AddConfiguration(hostingContext.Configuration.GetSection("Logging"));
                    logging.AddConsole();
                    logging.AddDebug();
                })
                .UseStartup<Startup>()
                .Build();

        }

我的docker .yml
