Hi Imesh, Yes, we had a look at Kubernetes too (discussed in [DISCUSS] Direct docker support from Stratos), and as of now our current understanding is Kubernetes, CoreOS, Stratos has set of conflicting interests such as scheduling docker instances, service grouping etc. (of course with few differentiations) :-)
Anyway, need to explore more and see whether we can leverage these while respecting Stratos' features. As per my current understanding Stratos will do most of the things that both CoreOS and Kubernetes do, after implementing the docker support.
