Introduction

Splash 无头浏览器渲染服务镜像，为 Scrapy/Crawler 提供 JavaScript 执行与 DOM 快照，解决动态页面抓取与 SPA 预渲染需求。

Details

whalebothelmsman/splash 基于 QtWebKit 暴露 HTTP API，爬虫通过 /render.html 传入 URL 与 wait 参数获取完整 HTML 或 PNG/HAR。与 Playwright 服务相比部署更轻、接口更简单，但对现代前端框架兼容性弱于 Chromium 方案。适合中小规模采集与内网监控探针；生产应限制并发、设置请求超时与 IP 白名单，避免被当作开放代理滥用。

快速启动

docker run -d --name splash \
  -p 8050:8050 \
  docker.io/whalebothelmsman/splash:latest

推荐实践

docker run -d --name splash \
  --restart unless-stopped \
  -p 8050:8050 \
  -e SPLASH_MAX_TIMEOUT=90 \
  -e SPLASH_SLOTS=10 \
  -v splash-filters:/etc/splash/filters \
  docker.io/whalebothelmsman/splash:3.5

核心参数说明

  • -p 8050:8050 — Splash HTTP API 端口
  • -e SPLASH_MAX_TIMEOUT — 单页渲染最长等待秒数
  • -e SPLASH_SLOTS — 并发渲染槽位数
  • -v splash-filters:/etc/splash/filters — 自定义 Lua 过滤脚本
  • --restart unless-stopped — 采集链路不中断
  • 固定 tag — 与 Scrapy-Splash 中间件版本对齐

无状态可 HPA 按 CPU 扩缩；爬虫 Pod 经 ClusterIP 调用，Ingress 勿公网暴露以免成为开放渲染代理。
