Decision brief
What it does—and where it fits
部署工作流、CI/CD流水线模式、Docker容器化、健康检查、回滚策略以及Web应用程序的生产就绪检查清单。
Not for
- Tasks that require unconfirmed production actions or broad system permissions.
- Environments where the pinned source and install steps cannot be inspected.

Installation
Inspect first. Install second.
The source command is displayed only when detected. A safe inspection prompt is always available so your agent can explain every action before execution.
npx skills add https://github.com/affaan-m/ECC --skill "docs/zh-CN/skills/deployment-patterns"Inspect the Agent Skill "deployment-patterns" from https://github.com/affaan-m/ECC/blob/4e973d3eaf92d97f8d2e2d8abb39d8bdc8711b38/docs/zh-CN/skills/deployment-patterns/SKILL.md at commit 4e973d3eaf92d97f8d2e2d8abb39d8bdc8711b38. List every install step, command, network request, credential, file read/write, external action, and rollback step. Explain whether it fits my task. Do not install or execute anything until I approve.

部署模式
生产环境部署工作流和 CI/CD 最佳实践。
何时启用
- 设置 CI/CD 流水线时
- 将应用容器化(Docker)时
- 规划部署策略(蓝绿、金丝雀、滚动)时
- 实现健康检查和就绪探针时
- 准备生产发布时
- 配置环境特定设置时
部署策略
滚动部署(默认)
逐步替换实例——在发布过程中,新旧版本同时运行。
实例 1: v1 → v2 (首次更新)
实例 2: v1 (仍在运行 v1)
实例 3: v1 (仍在运行 v1)
实例 1: v2
实例 2: v1 → v2 (第二次更新)
实例 3: v1
实例 1: v2
实例 2: v2
实例 3: v1 → v2 (最后更新)
优点: 零停机时间,渐进式发布 缺点: 两个版本同时运行——需要向后兼容的更改 适用场景: 标准部署,向后兼容的更改
蓝绿部署
运行两个相同的环境。原子化地切换流量。
Blue (v1) ← 流量
Green (v2) 空闲,运行新版本
# 验证后:
Blue (v1) 空闲(转为备用状态)
Green (v2) ← 流量
优点: 即时回滚(切换回蓝色环境),切换干净利落 缺点: 部署期间需要双倍的基础设施 适用场景: 关键服务,对问题零容忍
金丝雀部署
首先将一小部分流量路由到新版本。
v1:95% 的流量
v2:5% 的流量(金丝雀)
# 如果指标表现良好:
v1:50% 的流量
v2:50% 的流量
# 最终:
v2:100% 的流量
优点: 在全量发布前,通过真实流量发现问题 缺点: 需要流量分割基础设施和监控 适用场景: 高流量服务,风险性更改,功能标志

Docker 最佳实践
# 良好实践
- 使用特定版本标签(node:22-alpine,而非 node:latest)
- 采用多阶段构建以最小化镜像体积
- 以非 root 用户身份运行
- 优先复制依赖文件(利用分层缓存)
- 使用 .dockerignore 排除 node_modules、.git、tests 等文件
- 添加 HEALTHCHECK 指令
- 在 docker-compose 或 k8s 中设置资源限制
# 不良实践
- 以 root 身份运行
- 使用 :latest 标签
- 在单个 COPY 层中复制整个仓库
- 在生产镜像中安装开发依赖
- 在镜像中存储密钥(应使用环境变量或密钥管理器)

健康检查
健康检查端点
// Simple health check
app.get("/health", (req, res) => {
res.status(200).json({ status: "ok" });
});
// Detailed health check (for internal monitoring)
app.get("/health/detailed", async (req, res) => {
const checks = {
database: await checkDatabase(),
redis: await checkRedis(),
externalApi: await checkExternalApi(),
};
const allHealthy = Object.values(checks).every(c => c.status === "ok");
res.status(allHealthy ? 200 : 503).json({
status: allHealthy ? "ok" : "degraded",
timestamp: new Date().toISOString(),
version: process.env.APP_VERSION || "unknown",
uptime: process.uptime(),
checks,
});
});
async function checkDatabase(): Promise<HealthCheck> {
try {
await db.query("SELECT 1");
return { status: "ok", latency_ms: 2 };
} catch (err) {
return { status: "error", message: "Database unreachable" };
}
}

环境配置
十二要素应用模式
# All config via environment variables — never in code
DATABASE_URL=postgres://user:pass@host:5432/db
REDIS_URL=redis://host:6379/0
API_KEY=${API_KEY} # injected by secrets manager
LOG_LEVEL=info
PORT=3000
# Environment-specific behavior
NODE_ENV=production # or staging, development
APP_ENV=production # explicit app environment
配置验证
import { z } from "zod";
const envSchema = z.object({
NODE_ENV: z.enum(["development", "staging", "production"]),
PORT: z.coerce.number().default(3000),
DATABASE_URL: z.string().url(),
REDIS_URL: z.string().url(),
JWT_SECRET: z.string().min(32),
LOG_LEVEL: z.enum(["debug", "info", "warn", "error"]).default("info"),
});
// Validate at startup — fail fast if config is wrong
export const env = envSchema.parse(process.env);
回滚策略
即时回滚
# Docker/Kubernetes: point to previous image
kubectl rollout undo deployment/app
# Vercel: promote previous deployment
vercel rollback
# Railway: redeploy previous commit
railway up --commit <previous-sha>
# Database: rollback migration (if reversible)
npx prisma migrate resolve --rolled-back <migration-name>
