Native Multi-host networking
There is a lot to talk about the native multi-host networking and the overlay driver that makes it happen. The technical details are documented under https://github.com/docker/libnetwork/blob/master/docs/overlay.md.
Using the above experimental UI docker network, docker service and --publish-service, the user can exercise the power of multi-host networking.
Since network and service objects are globally significant, this feature requires distributed states provided by the libkv project.
Using libkv, the user can plug any of the supported Key-Value store (such as consul, etcd or zookeeper).
User can specify the Key-Value store of choice using the --cluster-store daemon flag, which takes configuration value of format PROVIDER:URL, where
PROVIDER is the name of the Key-Value store (such as consul, etcd or zookeeper) and
URL is the url to reach the Key-Value store.
Example : docker daemon --cluster-store=consul://localhost:8500
