第一章：docker selenium 环境部署

① 下载 selenium 镜像

首先拉取selenium/hub镜像。

执行命令：docker pull selenium/hub

然后拉取selenium/node-chrome镜像。

执行命令：docker pull selenium/node-chrome

docker images查看容器镜像。

② 容器 selenium 实例的创建与运行

创建容器实例：

docker run -d -P --name=hub selenium/hub

docker run -d -P --link=hub:hub selenium/node-chrome

查看当前运行的容器实例：

docker ps

查看所有的容器实例：

docker ps -a

可以通过docker start/stop 实例名来启动停用容器实例。

一般服务器重启后，就需要来启动容器了。

③ 浏览器访问 selenium Grid

docker ps可以查看生成的端口，通过本地ip + 端口号即可访问selenium Grid控制台。

可以看到浏览器版本相关信息。

可以看到相关配置信息。

④ docker 命令大全
