Between the DevOpsDays in Warsaw and Berlin Robert and I took a trip to the #Chefsummit in London. It had been a short trip indeed, however there are some things we would like to share with you, so read on ...

Wednesday morning: the first session I attended was amazingly enough about Docker. Everybody in then open space agreed on the fact that Docker is with no means a replacement for Chef. Instead it is integrating in a specific part of the deployment solution Chef is offering. A bunch of scenarios how people are using Chef in combination with Docker have been discussed. All in all the the combination of both varies from compiling and testing deliverables encapsulated in Docker containers to isolated services running as part of a platform.

Besides discussing the Docker container approach as such, it turned out that there is a huge demand for solutions answering the question of how Docker host cluster organization can be handled effectively. CoreOS is surely one of the key technologies that will play an important role in the future. Of course there are others like Project Atomic, for instance. Personally, I wouldn’t bet on Atomic at the moment as it seems that the development has been slowed down. This is of course just my impression, however I think a RHEL-based Docker cluster stack has some charming aspects. RHEL is sometimes a must in cooperate IT environments, so it would increase the acceptance level when introducing Docker. I collected a small list of Docker cluster solutions that are underway, some have been discussed in London. Check out the following candidates:

Additionally there are some off-the-shelf solutions that might be interesting:

The thing I find very interesting about this open space round: Docker and Docker orchestration gets a lot of attention in the Chef community. It is important and has already an impact on Chef.
