Don't get me wrong, I've been using containers for many many years. I run pure LXC on my desktop at home for simple containers. Containers are great in many situations. It's a shame LXC didn't get as much hype as Docker (not sure if Docker is LXC based anymore, but was for quite sometime).

However, you do require Docker (or LXC), and you need proper cgroup support in your kernel if you want true isolation. This is perfectly fine for myself and perhaps a few of my developers running Linux, but it starts to look less appealing in other environments.

Personally, I have to maintain multiple FreeBSD servers and even have a local FreeBSD machine for related purposes. I've also had to develop and maintain python applications for SmartOS (solaris based) machines.

Perhaps one day Docker will support Solaris Zones or FreeBSD jails, who knows. :)
