Hi Maarten,
old Docker images was running as root. New guacd with a default uid =
1000 (i think).
So i think it is a permission problem on the docker-volume for you
"shared_drive".
check the permissions on the host so that the docker run user has
read/write persmissions.
You can also "bash" into the guacd docker container and try a manual
"touch "/shared_drive/something.txt" to check if it is working.
best regards,
Tobias

I have a guacd instance running in docker. I tried both the main
branch as the 1.6 to build an image but I run into the same.
The latest 1.5 branch I am not able to build.
I am running on ARM64 (AWS Graviton instance).
I started the docker image like this:
docker run --quiet --name guacd --detach --net=host
--mount type=bind,src=/etc/guacamole,dst=/etc/guacamole
--mount
type=bind,src=/mnt/persistent_storage/guacamole_drive,dst=/shared_drive
-e GUACD_LOG_LEVEL=debug
--restart unless-stopped
registry.gitlab.com/agilepoint-emea/guacamole-server-build:1.6.0
Now I can connect to machines within this network using this guacd as
a proxy, over SSL, all working fine.
The only thing that does not work is the shared drive: the moment I
open the shared drive on the Windows machine, the connection
crashes/drops.
At this moment, these logs appear in docker:

removed.
I tried manually creating the desktop.ini file but this does not make
a difference, the connection still drops at the moment you open the
shared drive in explorer.
The folder mount does seem to work, because a Download folder appears
in it. Also I exec'ed into the container to verify if I could create a
file in there, which I can.
The folder is owned by guacd and writable anyway:
drwxrwxrwx 3 guacd guacd 6144 Mar 6 11:00 shared_drive
Thanks for any advice on how to resolve this.
Maarten
