Yes Imesh, that's what I mapped to a network partition (a cluster of
CoreOS). CoreOS currently lacks APIs (they released an alpha version of
Fleet API yesterday), and also as I mentioned in the other thread, Fleet
and Stratos has conflicting set of interests. As of now, I am not sure that
using Fleet is a viable option for us.
