Hi All,

Thanks,
Hi Fcwu,
Thanks for quick reply.
My Ubuntu 18.04 server on VMware. That's why I am using IP. I am using ldxe-vnc as image tag. When starting Image using run command then bash is not coming instead of log coming. I how may I debug.
Below output I am getting when running the docker images
dinesh@ubuntu3:~$ docker run -p 6080:80 -p 5900:5900 dorowu/ubuntu-desktop-lxde-vnc

Do you build by yourself? If not,
do docker pull dorowu/ubuntu-desktop-lxde-vnc again
here is my docker image ID
docker images|grep dorowu/ubuntu-desktop-lxde-vnc

Hi fcwu,
I pulled the the image and run, it working fine. Then what is the wrong with building image. Please guide me. I provided logs previously.
second thing docker is not running in background. So that after executing startup script it not leaving command prompt for us.
Please guide me .
Thanks,
first question: git clone --recursive .... You have to clone submodule too.
Update this line, https://github.com/fcwu/docker-ubuntu-vnc-desktop/blob/master/image/etc/supervisor/conf.d/supervisord.conf#L30
to
command=/usr/bin/openbox --startup /etc/xdg/openbox/autostart
You may append firefox & to /etc/xdg/openbox/autostart
Support OPENBOX_ARGS for appending "--startup /etc/..." without modifying image
I've found that when running the container using the new OPENBOX_ARGS environment variable, the supervisord.conf file is modified each time the container restarts, thus resulting in accumulating lines, such as:
[program:wm]
priority=15
command=/usr/bin/openbox --startup firefox --startup firefox --startup firefox command=/usr/bin/openbox --startup firefox --startup firefox --startup firefox command=/usr/bin/openbox --startup firefox --startup firefox --startup firefox command=/usr/bin/openbox --startup firefox --startup firefox
environment=DISPLAY=":1",HOME="/root",USER="root"
.. after restarting the container 4 times.
In addition, I have not had any luck on actually running firefox on container startup.
Hello @fcwu. Can I add bash script to /etc/xdg/openbox/autostart or some command? Need to run some GUI app with command roslaunch package some.launch. Need to run it automatically when user connects to 127.0.0.1:6080. Thanks
Just responding for whoever else wants to open a particular webpage on startup:
docker run -d --rm --name gui \
-e OPENBOX_ARGS='--startup "/usr/bin/firefox http://menziess.github.io"' \
-p 6080:80 -p 5900:5900 \
dorowu/ubuntu-desktop-lxde-vnc:bionic
And potentially for my own reference at some point. Thanks @fcwu
Hey @fcwu,
As I understand that feature correctly, it starts a command when the user logins with a web VNC client. Is that possible to start the GUI app when a container starts?
Use case: I need to automate a UI app, and I don't have any users to interact with a web GUI.
Thanks!
