Installing discourse in QNAP container station

I’m pretty new to discourse and docker, but would like to run discourse on my Qnap.

Has anybody so far managed to install discourse within Qnap’s Container Station?

I am trying to use Sam’s docker image, but so far was not able to run it.

Just managed to set it up on a virtual machine within Virtualization Station based on the original instructions. Challenge seems to come with running docker within LXC or docker. Still curious, if anybody was able to get it running in the Container Station.
