Some of us are still using Plan 9. I'm glad to see the connection between Plan 9 namespaces and containers mentioned, most people have missed that step in following the evolutionary pathway from unix chroot through BSD jails to Linux containerization. There is actually a semi-secret modern Plan 9 container-like service platform, but the Plan 9 community doesn't usually try to publicize/commercialize its work so almost nobody knows about it.

I don’t see the connection that clearly. You forget about OS/390 virtualisation. That would be what comes closest to what Docker is today, as the earliest innovation I can think of.

Oh really which service would that be? ;)
