FreeBSD introduced Jails in 1999.

I used my first Jail in 2001.

Docker was started over a decade later in 2013.

It’s reasonable to be confused why Jails lacks the mindshare. “Because it lacks all these other over-the-top features that we need” might be reasonable in response, except that Docker didn’t have any of these things on day 0 either.

Jails had a 14 year head start, Docker reinvents the wheel, and nor particularly well at first. Why did it succeed more than Jails did? It wasn’t because of the piss-poor native Mac support.

It seems pretty obvious that the big thing here is that most people ship apps on Linux, not on FreeBSD.
