关于 devops

面向 DevOps 任务的技能，涵盖 CI/CD、容器化、部署配置和基础设施自动化，并提供 Docker、GitHub Actions 与 Kubernetes 示例。

主要功能

  1. 01CI/CD 流水线配置
  2. 02Dockerfile 与 Compose 指导
  3. 03GitHub Actions 工作流
  4. 04Kubernetes 部署基础
  5. 05构建故障排查
  6. 06基础设施自动化

适用场景

  1. 01创建含测试和部署步骤的 CI/CD 工作流
  2. 02为本地开发配置应用容器
  3. 03配置 Kubernetes 部署
  4. 04排查构建失败

安装

复制下面的命令，在终端中运行。

$npx skills add https://github.com/htlin222/dotfiles --skill devops

安装后在 Claude Code 中输入/devops确认已加载。

详细介绍

DevOps

CI/CD 流水线、容器化和部署自动化。

适用场景

  • 设置 CI/CD 流水线
  • 创建 Dockerfile
  • 配置部署
  • 排查构建问题
  • 基础设施自动化

Docker

Dockerfile 最佳实践
# Multi-stage build
FROM node:20-alpine AS builder
WORKDIR /app
COPY package*.json ./
RUN npm ci
COPY . .
RUN npm run build

FROM node:20-alpine AS runner
WORKDIR /app
ENV NODE_ENV=production
COPY --from=builder /app/dist ./dist
COPY --from=builder /app/node_modules ./node_modules
USER node
EXPOSE 3000
CMD ["node", "dist/index.js"]
Docker Compose
version: "3.8"
services:
  app:
    build: .
    ports:
      - "3000:3000"
    environment:
      - DATABASE_URL=postgres://db:5432/app
    depends_on:
      - db
    healthcheck:
      test: ["CMD", "curl", "-f", "http://localhost:3000/health"]
      interval: 30s
      timeout: 10s
      retries: 3

  db:
    image: postgres:15-alpine
    volumes:
      - postgres_data:/var/lib/postgresql/data
    environment:
      - POSTGRES_DB=app
      - POSTGRES_PASSWORD_FILE=/run/secrets/db_password
    secrets:
      - db_password

volumes:
  postgres_data:

secrets:
  db_password:
    file: ./secrets/db_password.txt

GitHub Actions

name: CI/CD

on:
  push:
    branches: [main]
  pull_request:
    branches: [main]

jobs:
  test:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v4
      - uses: actions/setup-node@v4
        with:
          node-version: 20
          cache: "npm"
      - run: npm ci
      - run: npm test
      - run: npm run lint

  deploy:
    needs: test
    if: github.ref == 'refs/heads/main'
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v4
      - name: Deploy
        run: |
          echo "Deploying to production"

Kubernetes 基础知识

apiVersion: apps/v1
kind: Deployment
metadata:
  name: app
spec:
  replicas: 3
  selector:
    matchLabels:
      app: myapp
  template:
    metadata:
      labels:
        app: myapp
    spec:
      containers:
        - name: app
          image: myapp:latest
          ports:
            - containerPort: 3000
          resources:
            requests:
              memory: "128Mi"
              cpu: "100m"
            limits:
              memory: "256Mi"
              cpu: "200m"
          livenessProbe:
            httpGet:
              path: /health
              port: 3000
            initialDelaySeconds: 10
            periodSeconds: 30

示例

输入：“为此项目设置 CI/CD” **操作：**检测框架，创建 GitHub Actions 工作流，添加测试和部署步骤

输入：“将此应用容器化” **操作：**创建优化的 Dockerfile，为本地开发配置 docker-compose，并记录使用方法
