#启动主节点

docker run --name=hub -p 5001:4444 -e GRID_TIMEOUT=0 -e GRID_THROW_ON_CAPABILITY_NOT_PRESENT=true?-e GRID_NEW_SESSION_WAIT_TIMEOUT=-1 -e GRID_BROWSER_TIMEOUT=15000 -e GRID_TIMEOUT=30000 -e GRID_CLEAN_UP_CYCLE=30000 -d selenium/hub:3.7.1-beryllium

# 启动从节点， --link hub指定注册到hub主节点

docker run --name=chrome -p 5902:5900 -e NODE_MAX_INSTANCES=6 -e NODE_MAX_SESSION=6 -e NODE_REGISTER_CYCLE=5000 -e DBUS_SESSION_BUS_ADDRESS=/dev/null -v /dev/shm:/dev/shm --link hub -d selenium/node-chrome-debug:3.7.1-beryllium

默认vnc密码：secret

mac可通过访达连接服务器输入vnc://127.0.0.1:5902连接，输入vnc密码
