The docs state that they refer to the 0.9 version, while development is going on in the 0.11 branch, so the docs might be more of less out of date.
It seems that they have already implemented a large part of the Heroku infrastructure, including service discovery, auto balancing, cross-language events (using ZeroMQ) and that they are using it in production. All in all, an impressive feat!
It would be interesting to hear if anyone has experience running/using this outside of Yandex. The source code seems well written, though comments are quite sparse.
As Lazare remarked, it seems to directly compete with flynn.io. It is good to see that different high-level platforms are created based on docker. But it would be nice if these platforms would consist of modules (for example service discovery or messaging) that can be used without using the whole kitchen-sink. I am not sure if this is possible with cocaine.
BTW, the repo cocaine-core is quite a bit older (since 2011) than docker (since early 2013?). The docker-core readme states that docker support is "on it's way" so it is not clear how mature this is.
P.S. As adults and hackers, can we look beyond the name at the technology presented here?
