docker-x11-bridge

Pluggable X11 GUI for docker images

Run GUI applications in Docker with the same client(Xpra) on Windows, GNU/Linux, MacOS or web-browser over ssh or tcp.

(clickable!)

Try It!

docker run -d \
 --name x11-bridge \
 -e MODE="tcp" \
 -e XPRA_HTML="yes" \
 -e DISPLAY=:14 \
 -e XPRA_PASSWORD=111 \
 --net=host \
 jare/x11-bridge

docker run -d \
 --name emacs-1 \
 --volumes-from x11-bridge \
 -e DISPLAY=:14 \
 jare/emacs emacs

docker run -d \
 --name emacs-2 \
 --volumes-from x11-bridge \
 -e DISPLAY=:14 \
 jare/emacs emacs

Then visit http://localhost:10000/index.html?encoding=rgb32&password=111 See http://localhost:10000/connect.html for options

Or via ssh:

docker run -d \
 --name x11-bridge \
 -e MODE="ssh" \
 -v ~/.ssh/pub_rsa:/etc/pub-keys/me.pub \
 -e DISPLAY=:14 \
 --net=host \
 jare/x11-bridge

docker run -d \
 --name emacs-1 \
 --volumes-from x11-bridge \
 -e DISPLAY=:14 \
 jare/emacs emacs

docker run -d \
 --name emacs-2 \
 --volumes-from x11-bridge \
 -e DISPLAY=:14 \
 jare/emacs emacs

Then attach to the Xpra server via cmd tool or Xpra's GUI app: xpra attach --encoding=rgb --ssh="ssh -o StrictHostKeyChecking=no -p 22" ssh:xpra@localhost:14

Note -o StrictHostKeyChecking=no - it allows us to ignore server's identity instead adding it to known_hosts. If you want to rely on the identity you should use a privately built image.
All names of the pub keys should end with .pub i.e. /etc/pub-keys/<key_name>.pub
If Xpra lags, select Lowest Bandwidth when using Xpra app with a local Xpra host.
With Windows client you'll need Pageant you can convert your rsa keys to Pageant's format with PuTTYgen
GUI app in your image may requirelibGL.so.1 (provided by libgl1-mesa-glx on Ubuntu) and font
It is good idea to use ssl proxy or mount a certificate (see Xpra start-up message) if you want to use tcp or html mode beyond local network
You can modify the user
To use Xpra mmap(Linux): docker run ... -v /tmp/spacemacs-mmap/:/tmp/spacemacs-mmap/ ... jare/x11-bridge and attach with TMPDIR=/tmp/spacemacs-mmap/ xpra attach --mmap=yes --encoding=rgb --ssh="ssh -o StrictHostKeyChecking=no -p 22" ssh:xpra@localhost:14
