I have several past clients running docker in production just fine.

At my current job we run nearly all our services in docker.

I've replied to this type of comment on here at least a dozen times, it has nothing to do with docker, it is a lack of understanding how it all works.

Understand the history, understand the underlying concepts and this is no more complex than an advanced chroot.

Now on the tooling side, I personally stay away from any plug-ins and tools created by the docker team, they do docker best, let other tools manage dockers externalities.

I've used weave since it came out, and it's perfect for network management and service discovery.

I prefer to use mesos to manage container deploys.

There is an entirely usable workflow with docker but I like to let the specialists specialize, and so I just use docker (.10.1 even), because all the extra stuff is just making it bloated.

I'm testing newer versions on a case by case basis, but nothing new has come out that makes me want to upgrade yet.

And I'll probably keep using docker as long as it stays separate from all the cruft being added to the ecosystem.
