I'd like to build Mattermost on FreeBSD in order to test it on this platform and in the end, if found working without issues, create a port to include it in FreeBSD Ports Tree. I've seen in the comments, that simple 'make run' should regardless the platform, but that's not the case here. First issue was that it is meant to be 'gmake' instead of 'make', but then I am getting issues with docker not being available. Now, despite FreeBSD having containers available for almost a decade, these containers are not a Docker ones and even if one day Docker will be supported on FreeBSD, it is not the case today. So, the question is, is it possible to build Mattermost without Docker, and if it is, then how?
