.NET DevOps生态系统全景图
持续集成(CI)工具链
1. 构建自动化工具
.NET生态系统提供了多种强大的构建工具，满足不同复杂度的项目需求：
| 工具 | 特点 | 适用场景 |
|---|---|---|
| Cake | C# DSL，跨平台 | 复杂构建流程 |
| Nuke | 现代化构建系统 | 大型项目 |
| FAKE | F# Make，函数式 | F#项目 |
| MSBuild | 官方标准 | 简单项目 |
Cake构建脚本示例：
var target = Argument("target", "Default");
var configuration = Argument("configuration", "Release");
Task("Clean")
.Does(() =>
{
CleanDirectory("./artifacts");
CleanDirectories("./**/bin/" + configuration);
CleanDirectories("./**/obj/" + configuration);
});
Task("Restore")
.IsDependentOn("Clean")
.Does(() =>
{
DotNetRestore("./MySolution.sln");
});
Task("Build")
.IsDependentOn("Restore")
.Does(() =>
{
DotNetBuild("./MySolution.sln", new DotNetBuildSettings
{
Configuration = configuration,
NoRestore = true
});
});
Task("Test")
.IsDependentOn("Build")
.Does(() =>
{
DotNetTest("./MySolution.sln", new DotNetTestSettings
{
Configuration = configuration,
NoBuild = true,
NoRestore = true,
Collectors = new[] { "XPlat Code Coverage" }
});
});
Task("Pack")
.IsDependentOn("Test")
.Does(() =>
{
DotNetPack("./src/MyProject/MyProject.csproj", new DotNetPackSettings
{
Configuration = configuration,
NoBuild = true,
NoRestore = true,
OutputDirectory = "./artifacts"
});
});
Task("Default")
.IsDependentOn("Pack");
2. CI服务平台
.NET项目常用的CI/CD服务平台对比：
GitHub Actions配置示例：
name: .NET CI
on:
push:
branches: [ main ]
pull_request:
branches: [ main ]
jobs:
build:
runs-on: ubuntu-latest
steps:
- uses: actions/checkout@v3
- name: Setup .NET
uses: actions/setup-dotnet@v3
with:
dotnet-version: '8.0.x'
- name: Restore dependencies
run: dotnet restore
- name: Build
run: dotnet build --no-restore --configuration Release
- name: Test
run: dotnet test --no-build --configuration Release --collect:"XPlat Code Coverage"
- name: Pack
run: dotnet pack --no-build --configuration Release --output ./artifacts
- name: Upload artifacts
uses: actions/upload-artifact@v3
with:
name: packages
path: ./artifacts
自动化部署策略
1. 数据库迁移工具
数据库变更管理是DevOps中的重要环节，推荐使用以下工具：
DbUp迁移示例：
var upgrader = DeployChanges.To
.SqlDatabase(connectionString)
.WithScriptsEmbeddedInAssembly(Assembly.GetExecutingAssembly())
.LogToConsole()
.Build();
var result = upgrader.PerformUpgrade();
if (!result.Successful)
{
Console.ForegroundColor = ConsoleColor.Red;
Console.WriteLine(result.Error);
Console.ResetColor();
return -1;
}
Console.ForegroundColor = ConsoleColor.Green;
Console.WriteLine("Success!");
Console.ResetColor();
return 0;
Yuniql跨平台迁移：
# 初始化数据库
yuniql init -c "Server=localhost;Database=myapp;User Id=sa;Password=P@ssw0rd!"
# 创建新迁移脚本
yuniql new create_customers_table
# 运行迁移
yuniql run -c "Server=localhost;Database=myapp;User Id=sa;Password=P@ssw0rd!"
2. 应用部署方案
| 部署方式 | 工具 | 特点 |
|---|---|---|
| 容器化 | Docker | 环境一致性 |
| 云原生 | Kubernetes | 弹性伸缩 |
| 传统部署 | Octopus Deploy | 企业级功能 |
| 脚本部署 | PowerShell | 灵活定制 |
Dockerfile示例：
FROM mcr.microsoft.com/dotnet/aspnet:8.0 AS base
WORKDIR /app
EXPOSE 80
EXPOSE 443
FROM mcr.microsoft.com/dotnet/sdk:8.0 AS build
WORKDIR /src
COPY ["MyApp/MyApp.csproj", "MyApp/"]
RUN dotnet restore "MyApp/MyApp.csproj"
COPY . .
WORKDIR "/src/MyApp"
RUN dotnet build "MyApp.csproj" -c Release -o /app/build
FROM build AS publish
RUN dotnet publish "MyApp.csproj" -c Release -o /app/publish
FROM base AS final
WORKDIR /app
COPY --from=publish /app/publish .
ENTRYPOINT ["dotnet", "MyApp.dll"]
监控与日志体系
1. 日志管理框架
.NET日志生态系统提供了丰富的选择：
Serilog配置示例：
Log.Logger = new LoggerConfiguration()
.MinimumLevel.Information()
.MinimumLevel.Override("Microsoft", LogEventLevel.Warning)
.Enrich.FromLogContext()
.WriteTo.Console(
outputTemplate: "[{Timestamp:HH:mm:ss} {Level:u3}] {Message:lj}{NewLine}{Exception}")
.WriteTo.File(
"logs/app-.log",
rollingInterval: RollingInterval.Day,
outputTemplate: "{Timestamp:yyyy-MM-dd HH:mm:ss.fff zzz} [{Level:u3}] {Message:lj}{NewLine}{Exception}")
.WriteTo.ApplicationInsights(
TelemetryConfiguration.Active,
TelemetryConverter.Traces)
.CreateLogger();
2. 性能指标收集
App.Metrics配置示例：
var metrics = new MetricsBuilder()
.Configuration.Configure(options =>
{
options.DefaultContextLabel = "MyApp";
options.GlobalTags.Add("env", "production");
})
.OutputMetrics.AsPrometheusPlainText()
.OutputMetrics.AsGraphite()
.Build();
// 记录自定义指标
metrics.Measure.Counter.Increment(MetricsRegistry.SampleCounter);
metrics.Measure.Gauge.SetValue(MetricsRegistry.SampleGauge, 0.5);
metrics.Measure.Timer.Time(MetricsRegistry.SampleTimer, () => DoWork());
健康检查配置：
services.AddHealthChecks()
.AddSqlServer(connectionString, name: "database")
.AddRedis(redisConnectionString, name: "redis")
.AddAzureServiceBusQueue(sbConnectionString, "myqueue", name: "servicebus")
.AddApplicationInsightsPublisher();
app.UseHealthChecks("/health", new HealthCheckOptions
{
ResponseWriter = UIResponseWriter.WriteHealthCheckUIResponse
});
完整的DevOps流水线示例
端到端CI/CD流水线
多环境部署策略
public class DeploymentStrategy
{
public EnvironmentType Environment { get; set; }
public int ReplicaCount { get; set; }
public ResourceLimits Resources { get; set; }
public HealthCheckConfig HealthChecks { get; set; }
}
public enum EnvironmentType
{
Development,
Staging,
Production
}
public class KubernetesDeployer
{
public async Task DeployAsync(DeploymentStrategy strategy)
{
var config = KubernetesClientConfiguration.BuildConfigFromConfigFile();
using var client = new Kubernetes(config);
var deployment = CreateDeployment(strategy);
await client.AppsV1.CreateNamespacedDeploymentAsync(
deployment,
strategy.Environment.ToString().ToLower());
}
private V1Deployment CreateDeployment(DeploymentStrategy strategy)
{
return new V1Deployment
{
Metadata = new V1ObjectMeta
{
Name = $"myapp-{strategy.Environment}",
Labels = new Dictionary<string, string>
{
["app"] = "myapp",
["env"] = strategy.Environment.ToString()
}
},
Spec = new V1DeploymentSpec
{
Replicas = strategy.ReplicaCount,
Selector = new V1LabelSelector
{
MatchLabels = new Dictionary<string, string> { ["app"] = "myapp" }
},
Template = new V1PodTemplateSpec
{
Metadata = new V1ObjectMeta
{
Labels = new Dictionary<string, string> { ["app"] = "myapp" }
},
Spec = new V1PodSpec
{
Containers = new List<V1Container>
{
new V1Container
{
Name = "myapp",
Image = $"myregistry/myapp:{GetVersion(strategy.Environment)}",
Resources = strategy.Resources,
ReadinessProbe = strategy.HealthChecks?.ReadinessProbe,
LivenessProbe = strategy.HealthChecks?.LivenessProbe
}
}
}
}
}
};
}
}
监控告警与故障排除
1. 实时监控看板
构建完整的监控体系需要关注以下关键指标：
| 指标类别 | 具体指标 | 告警阈值 |
|---|---|---|
| 应用性能 | 响应时间，错误率 | >200ms，>1% |
| 资源使用 | CPU，内存，磁盘 | >80% |
| 业务指标 | 交易量，成功率 | -20%变化 |
| 依赖服务 | 数据库，缓存，消息队列 | 连接超时 |
2. 分布式追踪
services.AddOpenTelemetry()
.WithTracing(builder => builder
.AddSource("MyApp")
.SetResourceBuilder(ResourceBuilder.CreateDefault()
.AddService("MyApp", serviceVersion: "1.0.0"))
.AddAspNetCoreInstrumentation()
.AddHttpClientInstrumentation()
.AddSqlClientInstrumentation()
.AddOtlpExporter(options =>
{
options.Endpoint = new Uri("http://jaeger:4317");
}))
.WithMetrics(builder => builder
.AddMeter("MyApp")
.AddAspNetCoreInstrumentation()
.AddHttpClientInstrumentation()
.AddOtlpExporter(options =>
{
options.Endpoint = new Uri("http://prometheus:9090/api/v1/otlp");
}));
安全与合规性
1. 安全扫描集成
- name: Security Scan
uses: shiftleftio/scan-action@main
with:
output: reports
type: dotnet
- name: Dependency Check
uses: dependency-check/Dependency-Check_Action@main
with:
project: 'MyApp'
path: '.'
format: 'HTML'
2. 密钥管理
services.AddAzureKeyVault(
new Uri($"https://{Configuration["KeyVaultName"]}.vault.azure.net/"),
new DefaultAzureCredential());
services.Configure<DatabaseSettings>(options =>
{
options.ConnectionString = Configuration.GetConnectionString("Default");
});
// 使用IConfiguration直接访问密钥
var apiKey = Configuration["ApiKey"];
