I don't know of anything built-in to Docker that would do this, but seems like you could probably script something that checks the current version and the available version periodically and updates. I would think this would be pretty easy in bash/perl/python/etc. Also, looks like there is a project out there called Watchtower that helps with auto-updating containers: https://github.com/v2tec/watchtower To answer the original question, though, I don't think there is anything that could be added to the Guacamole Dockerfile that would automatically trigger this - you're going to have to add something else on. -Nick
