第一步：安装Serilog
使用NuGet包安装以下组件：
Serilog.AspNetCore
Serilog.Settings.Configuration
Serilog.Sinks.Console
Serilog.Sinks.Elasticsearch
第二步：修改Program.cs文件
public class Program
{ public static readonly string Namespace = typeof(Program).Namespace; public static readonly string AppName = Namespace.Substring(Namespace.LastIndexOf(‘.’, Namespace.LastIndexOf(‘.’) - 1) + 1); public static int Main(string[] args)
{ var configuration = GetConfiguration();
Log.Logger = CreateSerilogLogger(configuration); try {
Log.Information(“Configuring web host ({ApplicationContext})…”, AppName); var host = BuildWebHost(configuration, args);
Log.Information("Starting web host ({ApplicationContext})...", AppName);
host.Run(); return 0;
} catch (Exception ex)
{
Log.Fatal(ex, "Program terminated unexpectedly ({ApplicationContext})!", AppName); return 1;
} finally {
Log.CloseAndFlush();
}
} private static ILogger CreateSerilogLogger(IConfiguration configuration)
{ // var seqServerUrl = configuration\["Serilog:SeqServerUrl"\];
return new LoggerConfiguration()
.MinimumLevel.Verbose()
.Enrich.WithProperty("ApplicationContext", AppName)
.Enrich.FromLogContext()
.WriteTo.Console(new ElasticsearchJsonFormatter()) // .WriteTo.Console() // .WriteTo.Seq(string.IsNullOrWhiteSpace(seqServerUrl) ? "http://seq" : seqServerUrl) //写入sql
.ReadFrom.Configuration(configuration)
.CreateLogger();
} private static IConfiguration GetConfiguration()
{ var builder = new ConfigurationBuilder()
.SetBasePath(Directory.GetCurrentDirectory())
.AddJsonFile(“appsettings.json”, optional: false, reloadOnChange: true)
.AddEnvironmentVariables(); return builder.Build();
} private static IWebHost BuildWebHost(IConfiguration configuration, string[] args) => WebHost.CreateDefaultBuilder(args)
.CaptureStartupErrors(false)
.UseStartup
.UseConfiguration(configuration)
.UseSerilog()
.Build();
}
第三步：修改appsettings.json文件
{ “Serilog”: { “Using”: [ “Serilog.Sinks.Console” ], “MinimumLevel”: “Verbose”, “WriteTo”: [
{ “Name”: “Console” }
], “Enrich”: [ “FromLogContext”, “WithMachineName”, “WithThreadId” ], “Destructure”: [
{ "Name": "ToMaximumDepth", "Args": { "maximumDestructuringDepth": 4 }
},
{ "Name": "ToMaximumStringLength", "Args": { "maximumStringLength": 100 }
},
{ "Name": "ToMaximumCollectionCount", "Args": { "maximumCollectionCount": 10 }
}
\], "Properties": { "Application": "deploy-demo" }
}, “AllowedHosts”: “*“ }
第四步:打包成镜像运行
docker run -d -p 8003:80 –log-driver=fluentd –link elasticsearch –log-opt fluentd-address=192.168.0.186:24224 –network net_db –name deploydemo imagename
