Is it possible to run unix systems on (linux) docker?

Hi there! I’m wondering if there exists any way to run UNIX systems (such as Solaris 10 x86_64) as docker images on a Linux host. Maybe using “from scratch” images and trying to build the entire system (even the kernel)…

Is this completely impossible because of the different kernels?

Yes containers share the kernel with the host which means you can only run Linux containers on Linux hosts.
