On the topic of "why do we need a distributed KV store for an overlay network?" from the blog: there's a good blog post about why Kubernetes doesn't use Docker's libnetwork.

Thanks! I had almost forgotten about the container networking mayhem. Would love to find out what progress has been made over the past six months since the blog post was written.

Kubernetes now uses CNI to configure interfaces in its most common "kubenet" configuration, and (obviously) when you put it into "CNI" mode.

Most container network offerings - Calico, Flannel, Weave, etc. ship with a CNI plugin.

Docker have not altered their network plugin API.

(I work on Weave Net, including the plugins for both Docker and CNI)

Author seems to have missed that Calico also depends on etcd.
