Hello folks, Has anyone managed to add an extension in guacamole official image from docker hub ? If I bind the /root/.guacamole/extension ( default GUACAMOLE_HOME for the image ) to any host folder or non-existent folder to let docker create it, the following error keeps repeating : rm: cannot remove '/root/.guacamole/extensions': Device or resource busy However if I don't bind the volume, try to add manually the .jar in extensions and restart the container then the content of extensions folder will be removed, apart from the guacamole-auth-jdbc-postgresql-1.3.0.jar natively present.
Thanks for any idea !
