Many years before Linux containers, FreeBSD jails were easily packaged up via tar, deployed via scp, and started with minimal script. There wasn't much hype, it just worked. It was an excellent software packaging and distribution tool.

There wasn't a hub that I recall, nor was there tooling to use VMs so they could run on Windows/Mac. However, the main challenge, being able to distribute an "image" without requiring VM overhead, was solved elegantly. It just wasn't Linux, so it didn't make news.
