Question

我正在我的登台环境机器中使用来自官方docker映像的MongoDB 3.4.4实例。我使用MongoDB.Driver NuGet软件包2.5.0从代码进行连接。当我从已部署的应用程序连接时运行良好（从aspnetcore：2.0.3基本映像在docker容器中运行）。我的应用程序有一些集成测试。在应用程序项目和测试中，与Mongo创建的连接相同，如下所示：

services.AddSingleton<IMongoClient>(s =>
        {
            var config = s.GetService<ISettings>();
            var logger = s.GetService<ILogger<IMongoClient>>();
            var settings = MongoClientSettings.FromUrl(new MongoUrl("mongodb://dev:pass@192.168.0.163/authDb?connect=direct"));
            settings.MaxConnectionIdleTime = TimeSpan.FromSeconds(5);
            settings.MaxConnectionPoolSize = 1000;
            settings.MinConnectionPoolSize = 30;
            if (config.ActiveLogMongoQueries)
            {
                settings.ClusterConfigurator = (cb) =>
                {
                    cb.Subscribe<CommandStartedEvent>(
                    (e) =>
                    {
                        if (!IsServiceRequest(e.CommandName))
                        {
                            logger.LogInformation($"Mongo.Query DataBaseNameSpace: {e.DatabaseNamespace}. CommandName: {e.CommandName}. Command: {e.Command.ToString()}");
                        }
                    });
                };
            }

            return new MongoClient(settings);
        });
        services.AddTransient(s =>
        {
            var config = s.GetService<ISettings>();
            var dbName = "myDbName";
            var mongoConnectionString = new MongoUrl(config.MongoConnectionString);
            if (!string.IsNullOrEmpty(mongoConnectionString.DatabaseName))
            {
                dbName = mongoConnectionString.DatabaseName;
            }

            return s.GetService<IMongoClient>().GetDatabase(dbName);
        });

当我从Visual Studio IDE测试运行程序运行集成测试时，这也很好用。但是当我尝试使用gitlab CI自动运行测试项目时，我有了ConnectionTimeoutExeption：

System.AggregateException : One or more errors occurred.

我在gitlab-ci.yml中的测试阶段如下：

integrationtests:
  image: microsoft/aspnetcore-build:1.0-2.0 
  stage: integrationtests
  script:
  - dotnet test -c Release ./$PROJECT_NAME.IntegrationTests/$PROJECT_NAME.IntegrationTests.csproj 
  tags: 
    - docker
  only:  
    - schedules

主机192.168.0.163操作系统是Ubuntu，它还包含其他docker容器（如clickhouse），并且在gitlab Runner上运行测试时，与它们的连接没有问题。

我尝试将MongoDb.Driver更新到最新版本2.7.2，它解决了问题。但是出于某些原因，对我来说更好的是不更新驱动程序版本。我认为，如果代码在运行的应用程序中正常工作时不抛出异常，那么相同的代码在测试中也可以正常工作吗？任何避免更新MongoDb库和为什么会发生？我还看到了这篇帖子Connection times out after upgrading MongoDB.Driver from 2.7.0 to 2.7.1

但是，如果问题出在驱动程序上，为什么应用程序可以与旧的Mongo.Driver库一起正常工作？非常感谢！

已更新：今天，我尝试重新制作由gitlabRunner执行的步骤（如果我正确输入的话）。我在本地构建相同的映像，并在我的PC上使用docker运行它。我使用以下.Dockerfile进行构建：

FROM microsoft/aspnetcore-build:1.0-2.0 as base
WORKDIR /app
EXPOSE 80
FROM base AS final
WORKDIR /Test
COPY ./Test /Test
ENTRYPOINT /bin/bash

其中“测试”是我的解决方案文件夹。接下来，我使用以下命令进入容器：

docker run -it 2da12ce6cb7d

（在构建cmd之后由docker分配的名称）并尝试执行 - dotnet test -c Release ./ProjectName.IntegrationTests/ProjectName.IntegrationTests.csproj
并再次获得了这些例外。因此，因为我运行的应用程序（可以正常连接）使用microsoft / aspnetcore：2.0.3 Docker映像作为基础，所以问题可能出在其中。

MongoDb.Driver 2.5.0使用gitlab ci
