配置与管理 CI/CD 工具链

CI/CD 工具链概述

CI/CD 工具链是实现持续集成和持续部署的核心基础设施，它由多个工具组件组成，协同工作以自动化软件交付流程。Docker 作为容器化平台，与主流 CI/CD 工具深度集成，为工具链提供了标准化的运行环境。

工具链核心组件

源代码管理：
- Git（GitHub、GitLab、Bitbucket）
- 代码审查和协作
构建工具：
- Jenkins、GitLab CI、GitHub Actions
- 自动化构建和测试
容器化平台：
- Docker、Kubernetes
- 标准化部署环境
部署平台：
- 云平台（AWS、Azure、GCP）
- 容器编排平台

最佳实践

工具链标准化

# 标准化构建环境
FROM node:14-alpine AS base

# 安装通用工具
RUN apk add --no-cache \
    curl \
    git \
    bash \
    openssh

# 设置工作目录
WORKDIR /app

# 复制依赖文件
FROM base AS dependencies
COPY package*.json ./
RUN npm ci --only=production

# 构建阶段
FROM base AS build
COPY package*.json ./
RUN npm ci
COPY . .
RUN npm run build

# 运行阶段
FROM base AS runtime
COPY --from=dependencies /app/node_modules ./node_modules
COPY --from=build /app/dist ./dist
EXPOSE 3000
CMD ["node", "dist/index.js"]
