That's an interesting project but not quite the same - the Dash buttons use wifi to connect (instead of bluetooth) which lets them operate more independently.
I was able to crash the system without even trying.
After waiting for a 500MB something docker image download and running the container halted the host OSX machine while looping with errors (failed API connections, failed to load SIGAR, ...)
The screenshots looked great but the first steps experience were a deal breaker.
We've tested the Docker image on Mac OS X with boot2docker but of course there are always things that can go wrong.
It would be awesome if you could help us improve the Docker image by creating an issue at https://github.com/Graylog2/graylog2-images/issues with the error messages you've encountered when starting the container.
Oh, we got both kinds. We got country and western. ;-)
Seriously, the Docker image and the VM images are there to help people getting started and to quickly try out Graylog. We also offer regular OS packages in DEB and RPM formats (supporting Debian 7, Ubuntu 12.04 and 14.04, and CentOS 6) and a quick setup application (for a simple demo setup of Graylog and its dependencies). So choose your poison and be happy!
