我正在尝试使用Xvfb在Docker容器内运行Chrome无头.但是,虽然ps显示Chrome进程存在,但它没有到达我的测试网站.在Docker外部运行相同的命令是成功的.
Xvfb :0 -screen 0 1024x768x24 &
DISPLAY=:0 google-chrome http://mytestpage.com
在Docker中,我收到以下消息/错误：
Xlib: extension "RANDR" missing on display ":0".
Xlib: extension "RANDR" missing on display ":0".

在Docker外部运行相同的命令(它工作的地方)我收到消息/错误：

简单问题：运行Chrome时,为呼叫设置DISPLAY环境变量是不够的.还必须传递一个标志来禁用GPU,因为docker无法访问它并禁用沙盒.
我要导出显示：
export DISPLAY=:0
Xvfb :0 -screen 0 1024x768x24 &
google-chrome --disable-gpu --no-sandbox http://mytestpage.com
