It is true that the technologies existed for a while. I played with (Free)BSD jails and Solaris Zones long before Docker. Docker however made things "trivial" with the integration from container building, to public registry and docker-compose, which can make developer lives (depending on domain) much nicer. With jails and zones it was never as convenient.

I come from an ops background and I remember thinking at the time that Docker was in some ways a developer workaround to barriers that ops set up to limit what they could do and protect them from themselves.
