It requires too many Linuxisms which aren't part of FreeBSD's Linux ABI, so expecting Docker to work on FreeBSD is somehow wrong. > Docker is basically FreeBSD Jails, > with a few more features and a lot more security issues. It's surely possible to run a "jail equivalent" of the Docker application package in question (here: Discourse). > I have not looked into Discourse, but any application that requires Docker > is not worth using at this point. Discourse is not exactly _requiring_ Docker - there has been a prepackaged Docker "instance" of all the components you need to run Discourse, not more, not less. It should be possible to run Discourse the "traditional" way - using native FreeBSD technology. > If > you just cannot get Discourse working on FreeBSD, then by all means switch > to a Linux install instead.

It's somewhat comparable to a "pre-packaged VM image", more or less (probably less). Oh, and doing things like # wget http://getsomething.example.com | sudo bash is definitely _not_ the way you want to install software on FreeBSD. It rather seems to be a new Linuxism that has emerged during the recent years. :-) -- Polytropon Magdeburg, Germany Happy FreeBSD user since 4.0 Andra moi ennepe, Mousa, ...
