Cool so I got the extention template and so on. But where is the extentions 
folder located?

And wont it just get overwritten when the container gets reloaded?



Kind regards,

Hi.



I have googled and tried and tried and cant seem to rebrand my guacamole login 
screen.

How do i do this? everytime i chage something and restart the container it 
wipes all my changes and everything is lost.



Please note I am a docker noob and this is my first time using docker and 
guacamole.

First, you should not try to edit the files, directly, as they will be 
overwritten any time the web application (WAR) is re-deployed, which, in a 
Docker environment, will be any time the container is restarted.

In addition to that, Guacamole's extension framework allows for "branding" of 
the login page and other aspects of the interface.  This is covered in some 
level of detail on the guacamole-ext manual page:

http://guacamole.apache.org/doc/gug/guacamole-ext.html

Essentially you need a JAR file with a guac-manifest.json file, which tells 
Guacamole Client what resources to load, and then the resources themselves - 
customized CSS files, HTML files, etc.  I have one that provides a custom font 
for the interface that is in line with our corporate standards.

Once you've generated that JAR file you place it in the Guacamole extensions 
directory with any other extensions (e.g. authentication) you are loading.

If you need more detail or help, feel free to post back, here, and we can try 
to guide you further.
