Hi seiji, I'm the author of Docker.

There is hype around docker, for sure. The optimist in me likes to think that it's because people find the project useful and are excited about the possibilities of containers in general - which I believe are huge.

Me and the dotCloud team have been working on container technology since 2008. For a long time it felt like preaching in the desert - mostly because it required exotic patches to the kernel which made widespread adoption difficult. So it's very rewarding to see more people adopt containers, and of course it's great to be on the right side of the hype for a change. But if we hadn't been at the right place at the right time, someone else would have done it instead. Containers are just too important and useful to not blow up.
