To be clear - I think FreeBSD is an awesome project and the jails look solid, but it is really the Docker community and exploding Docker ecosystem that makes Docker appealing to me. For example, Red Hat embracing Docker means that I can build Docker containers for enterprises that embrace CentOS and Red Hat. None of the corporations or organizations I have worked with use or support FreeBSD, but they all support CentOS. Reference: http://www.infoworld.com/t/application-virtualization/red-ha...
