Forward VNC service port 5900 to host by
docker run -p 6080:80 -p 5900:5900 -v /dev/shm:/dev/shm dorowu/ubuntu-desktop-lxde-vnc
Now, open the vnc viewer and connect to port 5900. If you would like to protect vnc service by password, set environment variable VNC_PASSWORD, for example
docker run -p 6080:80 -p 5900:5900 -e VNC_PASSWORD=mypassword -v /dev/shm:/dev/shm dorowu/ubuntu-desktop-lxde-vnc
A prompt will ask password either in the browser or vnc viewer.
This image provides base access authentication of HTTP via HTTP_PASSWORD
docker run -p 6080:80 -e HTTP_PASSWORD=mypassword -v /dev/shm:/dev/shm dorowu/ubuntu-desktop-lxde-vnc
To connect with SSL, generate self signed SSL certificate first if you don't have it
mkdir -p ssl
openssl req -x509 -nodes -days 365 -newkey rsa:2048 -keyout ssl/nginx.key -out ssl/nginx.crt
Specify SSL port by SSL_PORT, certificate path to /etc/nginx/ssl, and forward it to 6081
docker run -p 6081:443 -e SSL_PORT=443 -v ${PWD}/ssl:/etc/nginx/ssl -v /dev/shm:/dev/shm dorowu/ubuntu-desktop-lxde-vnc
The Resolution of virtual desktop adapts browser window size when first connecting the server. You may choose a fixed resolution by passing RESOLUTION environment variable, for example
docker run -p 6080:80 -e RESOLUTION=1920x1080 -v /dev/shm:/dev/shm dorowu/ubuntu-desktop-lxde-vnc
The default user is root. You may change the user and password respectively by USER and PASSWORD environment variable, for example,
docker run -p 6080:80 -e USER=doro -e PASSWORD=password -v /dev/shm:/dev/shm dorowu/ubuntu-desktop-lxde-vnc
You may deploy this application to a subdirectory, for example /some-prefix/. You then can access application by http://127.0.0.1:6080/some-prefix/. This can be specified using the RELATIVE_URL_ROOT configuration option like this
docker run -p 6080:80 -e RELATIVE_URL_ROOT=some-prefix dorowu/ubuntu-desktop-lxde-vnc
NOTE: this variable should not have any leading and trailing splash (/)
It only works in Linux.
First of all, insert kernel module snd-aloop and specify 2 as the index of sound loop device
sudo modprobe snd-aloop index=2
Start the container
docker run -it --rm -p 6080:80 --device /dev/snd -e ALSADEV=hw:2,0 dorowu/ubuntu-desktop-lxde-vnc
where --device /dev/snd -e ALSADEV=hw:2,0 means to grant sound device to container and set basic ASLA config to use card 2.
Launch a browser with URL http://127.0.0.1:6080/#/?video, where video means to start with video mode. Now you can start Chromium in start menu (Internet -> Chromium Web Browser Sound) and try to play some video.
Following is the screen capture of these operations. Turn on your sound at the end of video!
Dockerfile and configuration can be generated by template.
- arch: one of
amd64orarmhf - flavor: refer to file in flavor/
flavor.yml - image: base image
- desktop: desktop environment which is set in flavor
- addon_package: Debian package to be installed which is set in flavor
Dockerfile and configuration are re-generate if they do not exist. Or you may force to re-generate by removing them with the command make clean.
