1.建立一个目录（将它命名为 fx-vnc ）用作构建上下文，并切换到该目录

[root@host1 ~]# mkdir -p fx-vnc
[root@host1 ~]# cd fx-vnc
[root@host1 fx-vnc]# pwd
/root/fx-vnc

2.在该目录中创建 Dockerfile

[root@host1 fx-vnc]# vi Dockerfile
[root@host1 fx-vnc]# cat Dockerfile
FROM ubuntu:20.04

ENV DEBIAN_FRONTEND=noninteractive

RUN apt update && \
    apt install -y --no-install-recommends \
        x11vnc \          
        xvfb \            
        firefox \         
        && \
    apt clean && \
    rm -rf /var/lib/apt/lists/*

RUN mkdir -p /root/.vnc

RUN x11vnc -storepasswd 1234 /root/.vnc/passwd

EXPOSE 5900

CMD ["bash", "-c", "Xvfb :0 -screen 0 1280x720x24 & export DISPLAY=:0 && firefox & x11vnc -forever -usepw -display :0"]

3.构建镜像

[root@host1 fx-vnc]# docker build --tag fx-vnc .

4.运行新镜像启动容器

[root@host1 fx-vnc]# docker run --rm -p 5900:5900 fx-vnc
19/09/2025 15:13:01 -usepw: found /root/.vnc/passwd
19/09/2025 15:13:01 x11vnc version: 0.9.16 lastmod: 2019-01-05  pid: 9
19/09/2025 15:13:01 Using X display :0
19/09/2025 15:13:01 rootwin: 0x50e reswin: 0x200001 dpy: 0xb664eba0
19/09/2025 15:13:01 
19/09/2025 15:13:01 ------------------ USEFUL INFORMATION ------------------
19/09/2025 15:13:01 X DAMAGE available on display, using it for polling hints.
19/09/2025 15:13:01   To disable this behavior use: '-noxdamage'
19/09/2025 15:13:01 
19/09/2025 15:13:01   Most compositing window managers like 'compiz' or 'beryl'
19/09/2025 15:13:01   cause X DAMAGE to fail, and so you may not see any screen
19/09/2025 15:13:01   updates via VNC.  Either disable 'compiz' (recommended) or
19/09/2025 15:13:01   supply the x11vnc '-noxdamage' command line option.
19/09/2025 15:13:01 
19/09/2025 15:13:01 Wireframing: -wireframe mode is in effect for window moves.
19/09/2025 15:13:01   If this yields undesired behavior (poor response, painting
19/09/2025 15:13:01   errors, etc) it may be disabled:
19/09/2025 15:13:01    - use '-nowf' to disable wireframing completely.
19/09/2025 15:13:01    - use '-nowcr' to disable the Copy Rectangle after the
19/09/2025 15:13:01      moved window is released in the new position.
19/09/2025 15:13:01   Also see the -help entry for tuning parameters.
19/09/2025 15:13:01   You can press 3 Alt_L's (Left "Alt" key) in a row to 
19/09/2025 15:13:01   repaint the screen, also see the -fixscreen option for
19/09/2025 15:13:01   periodic repaints.
19/09/2025 15:13:01 
19/09/2025 15:13:01 XFIXES available on display, resetting cursor mode
19/09/2025 15:13:01   to: '-cursor most'.
19/09/2025 15:13:01   to disable this behavior use: '-cursor arrow'
19/09/2025 15:13:01   or '-noxfixes'.
19/09/2025 15:13:01 using XFIXES for cursor drawing.
19/09/2025 15:13:01 GrabServer control via XTEST.
19/09/2025 15:13:01 
19/09/2025 15:13:01 Scroll Detection: -scrollcopyrect mode is in effect to
19/09/2025 15:13:01   use RECORD extension to try to detect scrolling windows
19/09/2025 15:13:01   (induced by either user keystroke or mouse input).
19/09/2025 15:13:01   If this yields undesired behavior (poor response, painting
19/09/2025 15:13:01   errors, etc) it may be disabled via: '-noscr'
19/09/2025 15:13:01   Also see the -help entry for tuning parameters.
19/09/2025 15:13:01   You can press 3 Alt_L's (Left "Alt" key) in a row to 
19/09/2025 15:13:01   repaint the screen, also see the -fixscreen option for
19/09/2025 15:13:01   periodic repaints.
19/09/2025 15:13:01 
19/09/2025 15:13:01 XKEYBOARD: number of keysyms per keycode 7 is greater
19/09/2025 15:13:01   than 4 and 51 keysyms are mapped above 4.
19/09/2025 15:13:01   Automatically switching to -xkb mode.
19/09/2025 15:13:01   If this makes the key mapping worse you can
19/09/2025 15:13:01   disable it with the "-noxkb" option.
19/09/2025 15:13:01   Also, remember "-remap DEAD" for accenting characters.
19/09/2025 15:13:01 
19/09/2025 15:13:01 X FBPM extension not supported.
Xlib:  extension "DPMS" missing on display ":0".
19/09/2025 15:13:01 X display is not capable of DPMS.
19/09/2025 15:13:01 --------------------------------------------------------
19/09/2025 15:13:01 
19/09/2025 15:13:01 Default visual ID: 0x21
19/09/2025 15:13:01 Read initial data from X display into framebuffer.
19/09/2025 15:13:01 initialize_screen: fb_depth/fb_bpp/fb_Bpl 24/32/5120
19/09/2025 15:13:01 
19/09/2025 15:13:01 X display :0 is 32bpp depth=24 true color

19/09/2025 15:13:01 Autoprobing selected TCP port 5900
19/09/2025 15:13:01 Autoprobing TCP6 port 
19/09/2025 15:13:01 Autoprobing selected TCP6 port 5900
19/09/2025 15:13:01 listen6: bind: Address already in use
19/09/2025 15:13:01 Not listening on IPv6 interface.
19/09/2025 15:13:01

19/09/2025 15:13:01 fast read: reset -wait  ms to: 10
19/09/2025 15:13:01 fast read: reset -defer ms to: 10
19/09/2025 15:13:01 The X server says there are 10 mouse buttons.
19/09/2025 15:13:01 screen setup finished.

******************************************************************************
Have you tried the x11vnc '-ncache' VNC client-side pixel caching feature yet?

The scheme stores pixel data offscreen on the VNC viewer side for faster
retrieval.  It should work with any VNC viewer.  Try it by running:

    x11vnc -ncache 10 ...

One can also add -ncache_cr for smooth 'copyrect' window motion.
More info: http://www.karlrunge.com/x11vnc/faq.html#faq-client-caching
