From the article: "The impossible challenge with Docker is to come with a working combination of kernel + distribution + docker version + filesystem. Right now. We don’t know of ANY combination that is stable (Maybe there isn’t any?)."
What combination of Docker version + distro + kernel + filesystem are you running, and how stable is it?

RHEL7.x - docker versions 1.8.x-1.10.x, mostly ext4. Stability is OK, aside from the things I mentioned.

One thing that bit me is that on RH 7.1 you _should_ use ext4[1], but on RH 7.2 you _need_ to use xfs[2]

The most important challenge that Docker faced was where it wanted to position itself, IWO, as a solid stable building block for container infrastructure, or as a all-in-one-alike container solution. Now that Docker has made its decision to push Swarm mode, it is getting better for productions. There are instabilities here and there but it will come around sooner or later.
It's certainly had its challenges (different versions of Docker clients causing havoc with different manifest versions, race conditions in the engine etc etc), but this article takes things a little far.
If you take pretty much any new technology like this make it a base part of your platform, you'll want support from a big vendor. To think otherwise would be naive.
There is definitely a debate to be had about Docker Inc's approach to production/enterprise rollouts though, but as a technology I'd say it's developing pretty much as I'd expect.
I've also seen Docker succeed in production despite the technical challenges. If you don't like the heat...
