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
