.netcore 使用surging框架发布到docker

demo运行在windows的docker中，系统是win10，所以需要先下载Docker for Windows，安装完毕后系统会重启，然后桌面上可以找到Docker for Windows的快捷图标，右下角有个鲸鱼小图标

单击右键，选择菜单中的Kitematic

会提示你下载Kitematic，自行下载后解压即可，将Kitematic快捷到桌面；

打开Kitematic，在搜索栏中下载好RabbitMQ、redis、consul相关镜像，因为这些是surging运行的先决条件。

接着去GitHub上下载surging网关项目，修改其中的gatewaySettings.json中Register下的Address地址，对应的事consul docker镜像的ip

具体如何查看其ip，看如下操作：

打开Kitematic，点击左下角，如图：

进入到命令窗口，输入docker container ls或者 docker ps -a 查看docker，

可以看到现在运行的docker的相关信息，

如图：

然后查看consul的相关配置，输入docker inspect 镜像的 containerID，如consul的id是b0e98b94638c，输入命令如下：docker inspect b0e98b94638c，

显示这个docker的配置，内容会很多，不过ip的信息在最后，如图

找到其中的ip是多少，然后修改surging网关中的consul地址为："Address": "172.17.0.4:8500"，其他配置根据上面的操作进行修改，如redis 镜像地址的查找和修改等；

修改好surging的网关配置后在Surging.ApiGateway项目上单击右键，由于我项目中已经添加过，所以该处为灰色，如图：

新建docker-Compose后修改其中docker-compose.yml的配置如下：

在后面添加docker的外部端口和内部端口的映射和网络模式，这里我们都使用桥接模式，包括之前的consul、RabbitMQ、redis都是同一模式，这样他们会在同一VLAN下，

然后运行网关，如下：

接下来新建一个解决方案，方案名随意，喜欢就好，由于时间比较短，这里我简单的处理，不清楚的可以留言

新建Service.A，然后在其下新建控制台应用Service.A、Service.B、Service.C，新建类库Service.A.Service、Service.B.Service、Service.C.Service；

编辑Service.A.csporj、Service.B.csporj、Service.C.csporj，如下

将其中的引用包都复制过去，分别修改一下对应的Service，即其中的<ProjectReference Include="..\Service.A.Service\Service.A.Service.csproj" />，Service.A引用Service.A.Service，Service.B引用Service.B.Service

Service.C引用Service.C.Service;

类库Service.A.Service、Service.B.Service、Service.C.Service中都引用

<PackageReference Include="surging" Version="0.5.4" />

如图：

由于代码很多地方相识，以下我只说Service.A,和Service.A.Service；

Service.A 中新增Configs文件夹，下面添加log4net.config，log4net.config代码如下：

<log4net>

 <root>

 <level value="Error" />

 <!-- <appender-ref ref="RollingLogFileAppender" /> -->

 <appender-ref ref="ErrorRollingLogFileAppender" />

 </root>

 <appender name="ErrorRollingLogFileAppender" type="log4net.Appender.RollingFileAppender,log4net" LEVEL="ERROR">

 <lockingModel type="log4net.Appender.FileAppender+MinimalLock" />

 <param name="File" value="c:\surging\Error\" />

 <param name="AppendToFile" value="true" />

 <param name="RollingStyle" value="Composite" />

 <param name="DatePattern" value="_yyyyMMddHH.TXT" />

 <param name="StaticLogFileName" value="false" />

 <param name="MaxSizeRollBackups" value="-1" />

 <param name="MaximumFileSize" value="5MB" />

 <layout type="log4net.Layout.PatternLayout,log4net">

  <param name="ConversionPattern" value="%date [%thread] %-5level %logger [%ndc] - %message%newline" />

 </layout>

 <filter type="log4net.Filter.LevelRangeFilter">

  <param name="LevelMin" value="ERROR" />

  <param name="LevelMax" value="FATAL" />

 </filter>

 </appender>

</log4net>

然后新增cacheSettings.json其中Map:Properties下的value的值是redis地址

{
 "CachingSettings": [
  {
  "Id": "ddlCache",
  "Class": "Surging.Core.Caching.RedisCache.RedisContext,Surging.Core.Caching",
  "Properties": [
   {
   "Name": "appRuleFile",
   "Ref": "rule"
   },
   {
   "Name": "dataContextPool",
   "Ref": "ddls_sample",
   "Maps": [
    {
    "Name": "Redis",
    "Properties": [
    {
     "value": "172.17.0.2:6379::1"
     }
    ]
    },
    {
    "Name": "MemoryCache"
    }
   ]
   },
   {
   "Name": "defaultExpireTime",
   "value": "120"
   },
   {
   "Name": "connectTimeout",
   "Value": "120"
   },
   {
   "Name": "minSize",
   "Value": "1"

   },
   {
   "Name": "maxSize",
   "Value": "10"
   }
  ]
  }
 ]
}

新增eventBusSettings.json，其中的EventBusConnection对应的是RabbitMQ docker的地址

{
 "EventBusConnection": "172.17.0.3",
 "EventBusUserName": "guest",
 "EventBusPassword": "guest"
} 

Program.cs的代码如下

using Autofac;
using Surging.Core.Codec.MessagePack;
using Surging.Core.Consul;
using Surging.Core.Consul.Configurations;
using Surging.Core.CPlatform;
using Surging.Core.CPlatform.Utilities;
using Surging.Core.DotNetty;
using Surging.Core.EventBusRabbitMQ;
using Surging.Core.Log4net;
using Surging.Core.ProxyGenerator;
using Surging.Core.ServiceHosting;
using Surging.Core.ServiceHosting.Internal.Implementation;
using System;
using System.Text;
namespace Service.A
{
 class Program
 {
  static void Main(string[] args)
  {
   NewMethod();
  }
  private static void NewMethod()

  {

   Encoding.RegisterProvider(CodePagesEncodingProvider.Instance);

   var host = new ServiceHostBuilder()

    .RegisterServices(builder =>

    {

     builder.AddMicroService(option =>

     {

      option.AddServiceRuntime();

      option.AddRelateService();

      //option.UseZooKeeperManager(new ConfigInfo("127.0.0.1:2181"));

      option.UseConsulManager(new ConfigInfo("172.17.0.4:8500"));

      option.UseDotNettyTransport();

      option.UseRabbitMQTransport();

      option.AddRabbitMQAdapt();

      //option.UseProtoBufferCodec();

      option.UseMessagePackCodec();

      builder.Register(p => new CPlatformContainer(ServiceLocator.Current));

     });

    })

    .SubscribeAt()

    .UseLog4net("Configs/log4net.config")

    //.UseServer("127.0.0.1", 98)

    //.UseServer("127.0.0.1", 98，“true”) //自动生成Token

    //.UseServer("127.0.0.1", 98，“123456789”) //固定密码Token

    .UseServer(options =>

    {

     options.Ip = "172.17.0.6";

     options.Port = 9990;

     options.Token = "True";

     options.ExecutionTimeoutInMilliseconds = 30000;

     options.MaxConcurrentRequests = 200;

     options.NotRelatedAssemblyFiles = "Centa.Agency.Application.DTO\\w*|StackExchange.Redis\\w*";

    })

    .UseProxy()

    .UseStartup<Startup>()

    .Build();

   using (host.Run())

   {
    Console.WriteLine($"服务端启动成功，{DateTime.Now}。");
   }
  }
 }
}

新增Startup.cs

using Autofac;
using Autofac.Extensions.DependencyInjection;
using Microsoft.Extensions.Configuration;
using Microsoft.Extensions.DependencyInjection;
using Microsoft.Extensions.Logging;
using Surging.Core.Caching.Configurations;
using Surging.Core.CPlatform.Utilities;
using Surging.Core.EventBusRabbitMQ.Configurations;
using System;
namespace Service.A
{
 public class Startup

 {
  public Startup()
  {
   var config = new ConfigurationBuilder()

   .SetBasePath(AppContext.BaseDirectory);

   ConfigureEventBus(config);

   //ConfigureCache(config);

  }
  public IContainer ConfigureServices(ContainerBuilder builder)
  {
   var services = new ServiceCollection();
   ConfigureLogging(services);
   builder.Populate(services);
   ServiceLocator.Current = builder.Build();
   return ServiceLocator.Current;
  }
  public void Configure(IContainer app)
  {
   app.Resolve<ILoggerFactory>()
     .AddConsole((c, l) => (int)l >= 3);

  }

  #region 私有方法
  /// <summary>
  /// 配置日志服务
  /// </summary>
  /// <param name="services"></param>
  private void ConfigureLogging(IServiceCollection services)
  {
   services.AddLogging();
  }

  private static void ConfigureEventBus(IConfigurationBuilder build)

  {
   build

   .AddEventBusFile("eventBusSettings.json", optional: false);
  } 

  /// <summary>
  /// 配置缓存服务
  /// </summary>
  private void ConfigureCache(IConfigurationBuilder build)
  {
   build
    .AddCacheFile("cacheSettings.json", optional: false);
  }
  #endregion
 }
}

Service.A.Service 类库下新增AService.cs

using Surging.Core.ProxyGenerator;
using System;
using System.Collections.Generic;
using System.Text;
using System.Threading.Tasks;
namespace Service.A.Service

{
 public class AService:ProxyServiceBase,IAService

 {
  public Task<string> SayHello(string name)

  {
   return Task.FromResult($"{name} say : hello");
  }
 }
}

新增IAService.cs

using Surging.Core.CPlatform.Ioc;
using Surging.Core.CPlatform.Runtime.Server.Implementation.ServiceDiscovery.Attributes;
using System;
using System.Collections.Generic;
using System.Text;
using System.Threading.Tasks;
namespace Service.A.Service
{
 [ServiceBundle("api/{Service}")]
 public interface IAService : IServiceKey
 {
  Task<string> SayHello(string name);
 }
}

其他类库和服务与以上代码基本无二，这里不在赘述。不清楚的可以留言

所有代码都处理好后，在Service.A、Service.B、Service.C项目上右键新增docker支持文件，然后会生成一下文件

修改其中的docker-compose.yml

version: '3'

services:

 service.a:

 image: servicea

 ports:

  - "127.0.0.1:9990:9990"

 network_mode: "bridge"

 build:

  context: .

  dockerfile: Service.A/Dockerfile

 service.b:

 image: serviceb

 ports:

  - "127.0.0.1:9991:9991"

 network_mode: "bridge"

 build:

  context: .

  dockerfile: Service.B/Dockerfile

 service.c:

 image: servicec

 ports:

  - "127.0.0.1:9992:9992"

 network_mode: "bridge"

 build:

  context: .

  dockerfile: Service.C/Dockerfile

 webapplication1:

 image: webapplication1

 build:

  context: .

  dockerfile: ../WebApplication1/Dockerfile

然后选择docker运行即可

最后访问surging网关，即可看见效果
