A day ago I finally got a working container with Xpra and the
proxy in front of it running without Jupyter notebook server.
JupyterHub supports a bunch of different Authenticators and Spawners
(for example, we are using KubeSpawner to spawn single-user
containers in a Kubernetes cloud)
I don't know any other remote desktop project which could be
as flexible as JupyterHub+Xpra combination.
AFAIK x2go and Apache Guacamole support some sort of load balancing,
but I don't think they support, for example, Kubernetes.
The disadvantage is that the only way to access Xpra is its HTML5 client.
I'm attaching the Dockerfile and the entry script I'm using.
This is the first version which is not ideal and has some workarounds and
dirty hacks I had to use to make it working.
I've found that Xpra became kinda rebellious: it ignores the orders I
give it
not to launch dbus and pulseaudio and not to put sockets in an original
HOME directory
(which is a network-mounted FS which doesn't seem to support sockets and
pipes)
so I had to install nss-sssd connector to map UIDs to usernames so that
the dbus-launch doesn't refuse to start and I had to override the HOME
variable.
The python script is not attached to the mailing list, only the Dockerfile
has been delivered embedded in the email.
Can you share again the entrypoint script?
Trying to attach to this message. If it fails see

I am curious of the solution you found for the home folder and the unix
socket file.
I mount an empty volume at /scratch and point HOME to this directory.
Xpra seem to ignore --socket-dir[s] options...
I also run JupyterHub which spwans docker containers running xpra.
I shared my Dockerfile in another thread here on the mailing list (I just
sent it again copy and pasted in an email since the attachment did not get
through).
BTW, you don't have to run `apt-get clean` each time, see
/etc/apt/apt.conf.d/docker-clean in the Ubuntu Docker images.
I just run that Dockerfile with vanilla JupyterHub, without nbserverproxy
and things works, although on the slow side.
So you are just running Xpra without anything in front of it
and you don't require authentication to access it?
