Introduction

Selenium Grid Hub 镜像，协调 WebDriver 会话分发至 Node 节点，适合浏览器自动化测试 CI 与 E2E 回归，需配合 selenium/node 同网部署。

Details

selenium/hub 运行 Grid 4 中央调度器，接收测试框架连接并分配至 Chrome/Firefox Node。典型用于 Jenkins/GitLab CI 并行 UI 测试，与 Playwright 云服务相比可完全私有化。镜像仅为 Hub，需同 compose 或 K8s 部署 node-chrome 等 worker；生产固定 tag、Hub 限制内网并规划 Node 资源与 session 超时。

快速启动

docker run -d --name selenium-hub \
  -p 4444:4444 \
  docker.io/selenium/hub:latest

推荐实践

docker run -d --name selenium-hub \
  --restart unless-stopped \
  -p 4444:4444 -p 4442:4442 -p 4443:4443 \
  -e SE_SESSION_REQUEST_TIMEOUT=300 \
  -e SE_NODE_MAX_SESSIONS=5 \
  docker.io/selenium/hub:4.25.0

核心参数说明

  • -p 4444:4444 — WebDriver 与 Grid UI 端口
  • -p 4442:4442 -p 4443:4443 — Grid 事件总线端口
  • -e SE_SESSION_REQUEST_TIMEOUT — 会话排队超时秒数
  • -e SE_NODE_MAX_SESSIONS — 每 Node 最大并发 session
  • --restart unless-stopped — CI 测试 Hub 持续在线
  • 固定 tag — 与 node 镜像 Grid 大版本 pin

Node Deployment 独立扩缩；CI namespace 内 NetworkPolicy 限制 Hub 访问，Node 需足够 CPU/内存跑 headless 浏览器。
