regarding the documentation: https://guacamole.apache.org/doc/gug/guacamole-docker.html#guacamole-docker-guacamole-home
something like this should do the trick (if i understand your problem correctly) e.g.: ``` podman run -ti --rm -v /tmp/branding.jar:/tmp/extensions/branding.jar:rw,Z -e GUACAMOLE_HOME=/tmp/ ... -p 8080:8080 guacamole/guacamole ``` the GUACAMOLE_HOME env variable needs to point to a directory with the correct structure, in this case the extensions directory needs to be present, with the jar file inside... the jar file is from here: https://github.com/Zer0CoolX/guacamole-customize-loginscreen-extension (maybe this 'enough customization' for you...)

But where is the extentions folder located? And wont it just get overwritten when the container gets reloaded? You'll probably have to modify the startup script for the container to pull in the custom branding extension prior to starting Tomcat. My Docker skills are not all that complete, so I can't tell you without some trial-and-error exactly how you'd accomplish that, but I know that you can specify custom startup commands for containers after you deploy them, so I'd guess you just want to make sure you deploy that extension every time. Also, I believe the extension would only be overwritten if you reload the container from the original image - I would think it would persist between starts and stops. I could be wrong about that, though - like I said, my Docker familiarity is a bit sketchy. Maybe others on the list can offer their experiences and advice :-). -Nick
