Might be interesting for the docker runtime in the future as well. That is, assuming k8s spends enough time on supporting alternatives like rkt as well as docker.
Do you think k8s's support for docker and rkt will become the same as the interface becomes standardized with the Open Container Initiative? https://www.opencontainers.org/about
There is currently a ongoing refactoring of the container communication stuff in kubernetes to remove all container engine specific code and just use the Open Container Runtime Interface. This allows any container engine to run with kubernetes as long as they implement the Open Container Runtime Interface.
