#2Great news. I'm not a fan of Docker's new monolithic approach to containerization. Things like orchestration and networking should not be included in docker, but rather pluggable.

#3This looks very interesting - it'll be really useful to have something like Docker that isn't so monolithic - it should be much more composable in new ways.

#4it's a very exciting time for Linux Containers. it's been a fun to watch the evolution from BSD jails to lxc to docker, but the rate of innovation and usefulness is certainly accelerating. it sure seems like rocket's approach will be much less of a black box than docker images/registry, which should make it much more approachable to people trying to understand what linux containers are all about.

#5Would there be support for Socket Activation? (something that is still missing on Docker..)

Yes, we have prototyped doing socket activation with rocket already but the patches haven't been merged. So, yes, the intention is to make socket activation work.

Absolutely!

#8I'm all for a new container runtime if it lets me start containers as a non-root user. Allowing non-root users to start containers would open up a whole new level of applications, particularly on multi-tenant HPC-style clusters.

#9Interesting takeaways from the post:
* Despite Brandon Philips (CoreOS CTO) serving on the Docker governance board, Docker has aggressively expanded their scope well beyond their original container manifesto.
* CoreOS believes the Docker runtime is now too unwieldy and "fundamentally flawed"; the unwritten word that really sprung to mind was that Docker was getting "greedy."
* CoreOS reaffirms their original operating model of being capable of running their infrastructure on and with Docker.
* Rocket is CoreOS's answer to stay true to the "simple composable building block" mantra.

#10Woohoo! Docker is going off the rails trying to roll container orchestration into it. Kubernetes is arguably a "larger" project than docker, and docker is out of their depth thinking they can just roll such a feature in.
