我试图在ssh。
的docker容器中使用带有图形界面的程序目前,我在一台外部机器上通过ssh连接,其中docker和容器正在运行。在主机上我可以启动像firefox这样正确显示的程序。建立连接:
ssh -Y root@host
当我在docker容器中尝试使用firefox
图像时(见下文):
docker run -it --privileged --rm \
-e DISPLAY=$DISPLAY \
-v /tmp/.X11-unix:/tmp/.X11-unix \
-v /root/.Xauthority:/root/.Xauthority:rw \
firefox
我得到:
Error: cannot open display: localhost:11.0
我已经尝试在主机上设置xhost +
,但它仍然无效。
主机运行Scientific Linux release 7.2
,并使用。创建docker镜像
来自 http://fabiorehm.com/blog/2014/09/11/running-gui-apps-with-docker/的Dockerfile:
FROM ubuntu:14.04
RUN apt-get update && apt-get install -y firefox
# Replace 1000 with your user / group id
RUN export uid=1000 gid=1000 && \
mkdir -p /home/developer && \
echo "developer:x:${uid}:${gid}:Developer,,,:/home/developer:/bin/bash" >> /etc/passwd && \
echo "developer:x:${uid}:" >> /etc/group && \
echo "developer ALL=(ALL) NOPASSWD: ALL" > /etc/sudoers.d/developer && \
chmod 0440 /etc/sudoers.d/developer && \
chown ${uid}:${gid} -R /home/developer
USER developer
ENV HOME /home/developer
CMD /usr/bin/firefox

将unit Unit1;
interface
uses
Windows, Messages, SysUtils, Variants, Classes, Graphics, Controls, Forms,
Dialogs, ExtCtrls;
type
TForm1 = class(TForm)
Panel1: TPanel;
procedure FormCreate(Sender: TObject);
end;
var
Form1: TForm1;
implementation
{$R *.dfm}
procedure MD(Instance, Sender: TObject; Button: TMouseButton; Shift: TShiftState; X, Y: Integer);
begin
form1.caption:= inttostr(x)+ ' '+ inttostr(y);
end;
procedure TForm1.FormCreate(Sender: TObject);
function MakeMethod(data, code: pointer): TMethod;
begin
result.Data:= data;
result.Code:= code;
end;
begin
panel1.OnMouseDown:= TMouseEvent(MakeMethod(nil, @MD));
end;
end.
添加到--net=host
解决了这个问题。
