puppeteer 示例

Dockerfile 注意事项

  • 使用 alanway/puppeteer 镜像,
  • 设置环境变量 ENV PUPPETEER_SKIP_CHROMIUM_DOWNLOAD true 跳过 Chromium 的下载. (因为alanway/puppeteer里已经下载配置好Chromium了)

以下是参考示例:

FROM alanway/puppeteer

ENV PUPPETEER_SKIP_CHROMIUM_DOWNLOAD true

WORKDIR /app

COPY src/ ./src
COPY package.json package-lock.json ./

RUN npm install

Node 代码注意事项

  • puppeteer 启动时注意设置以下选项:
    • headless: true Docker 环境必须无头浏览
    • executablePath: 'google-chrome-stable' 设置Chrome的的路径
    • args: ['--no-sandbox', '--disable-setuid-sandbox'] 禁用Chrome的沙盒特性，否则使用本镜像是会出现异常: Failed to move to new namespace: PID namespaces supported, Network namespace supported, but failed: errno = Operation not permitted

以下是参考代码:

const puppeteer = require("puppeteer");
const browser = await puppeteer.launch({
    headless: true,
    executablePath: 'google-chrome-stable',
    args: ['--no-sandbox', '--disable-setuid-sandbox'],
    "userDataDir": "logs/chrome", // 设置 Chrome 数据存储路径, 可忽略
});
