Docker组合指定的端口不映射以连接到健康检查端点

Question

我是Docker的新手。这是我正在使用的布局。我在Docker组成的文件中有2个项目。 DotNet6 Web API和MVC Web应用程序。在Web API startup.cs中，我有以下代码，可以使用Aspnetcore.healthchecks.ui获得健康状态，如果我浏览到端点，我会得到健康检查值的JSON对象（此部分工作）

app.UseEndpoints(endpoints =>
   {
    endpoints.MapControllers();
    endpoints.MapHealthChecks("/hc", new HealthCheckOptions
      {
        Predicate = _ => true,
        ResponseWriter = UIResponseWriter.WriteHealthCheckUIResponse
      });
  });

我有一个WebStatus .Net Core MVC应用程序的工作是使用HealthCheck UI显示健康统计数据。 对此的应用程序是：

{
  "HealthChecks-UI": {
    "HealthChecks": [
      {
        "Name": "TestApp API Health Check",
        "Uri": "https://localhost:7100/hc"
      },
      {
        "Name": "TestApp API Health Check (Local)",
        "Uri": "https://localhost:7141/hc"
      }
    ],
    "Webhooks": [
      {
        "Name": "",
        "Uri": "",
        "Payload": "",
        "RestoredPayload": ""
      }
    ],
    "EvaluationTimeOnSeconds": 10,
    "MinimumSecondsBetweenFailureNotifications": 60
  },
  "Logging": {
    "LogLevel": {
      "Default": "Information",
      "Microsoft": "Warning",
      "Microsoft.Hosting.Lifetime": "Information"
    }
  },
  "AllowedHosts": "*"
}

则Docker组成的文件如下所示

version: '3.4'

services:
  testapp.api:
    environment:
      - ASPNETCORE_ENVIRONMENT=Development
      - ASPNETCORE_URLS=https://+:443;http://+:80
    ports:
      - "8005:80"
      - "7100:443"
    volumes:
      - ${APPDATA}/Microsoft/UserSecrets:/root/.microsoft/usersecrets:ro
      - ${APPDATA}/ASP.NET/Https:/root/.aspnet/https:ro

  webstatus:
    environment:
      - ASPNETCORE_ENVIRONMENT=Development
      - ASPNETCORE_URLS=https://+:443;http://+:80
      - HealthChecksUI__HealthChecks__0__Name=Test App API Health Check
      - HealthChecksUI__HealthChecks__0__Uri=https://testapp.api/hc
    ports:
      - "8006:80"
      - "7101:443"
    depends_on:
      - testapp.api
    volumes:
      - ${APPDATA}/Microsoft/UserSecrets:/root/.microsoft/usersecrets:ro
      - ${APPDATA}/ASP.NET/Https:/root/.aspnet/https:ro

如果我在没有Docker的两个项目中启动两个项目，一切正常，WebStatus应用程序显示API的健康状况如下所预期， ！但是，当我使用Docker组合运行此功能时，它行不通。我用来进入WebStatus应用程序的URL是https：// localhost：7101/healthchecks-ui＃/healthchecks

Answer 1

事实证明，WebStatus应用程序无法通过HTTPS进行通信。我更改了所有内容以通过HTTP进行交流，然后开始工作

version: '3.4'

services:
  testapp.api:
    environment:
      - ASPNETCORE_ENVIRONMENT=Development
    ports:
      - "8005:80"
    volumes:
      - ${APPDATA}/Microsoft/UserSecrets:/root/.microsoft/usersecrets:ro
      - ${APPDATA}/ASP.NET/Https:/root/.aspnet/https:ro

  webstatus:
    environment:
      - ASPNETCORE_ENVIRONMENT=Development
      - HealthChecksUI__HealthChecks__0__Name=Test App API Health Check
      - HealthChecksUI__HealthChecks__0__Uri=http://testapp.api/hc
    ports:
      - "8006:80"
    depends_on:
      - testapp.api
    volumes:
      - ${APPDATA}/Microsoft/UserSecrets:/root/.microsoft/usersecrets:ro
      - ${APPDATA}/ASP.NET/Https:/root/.aspnet/https:ro
