Hi, Any extensions that you copy into the Docker container within the directory "/etc/guacamole/" will be automatically relocated to the correct Guacamole directory. You don't need to create your own image to use extensions. When your container starts, it will move the extensions to the correct location (/home/guacamole/.guacamole/).
The same applies to your guacamole.properties file. You should configure this in the volume: volumes: ./guacamole:/etc/guacamole On the host, keep your extensions in: ./guacamole/extensions I hope this helps!
