When resolving names in swarm mode, services with exposed ports are connected to user overlay network, ingress network, and local (docker_gwbridge) networks. Name resolution should prioritize returning the VIP/IPs on user overlay network over ingress and local networks. Sandbox.ResolveName implemented this by taking the list of endpoints, splitting the list into 3 separate lists based on the type of network that the endpoint was attached to (dynamic, ingress, local), and then creating a new list, applying the networks in that order. This patch refactors that logic to use a custom sorter (sort.Interface), which makes the code more transparent, and prevents iterating over the list of endpoints multiple times.

libnetwork - networking for containers
Libnetwork provides a native Go implementation for connecting containers
The goal of libnetwork is to deliver a robust Container Network Model that provides a consistent programming interface and the required network abstractions for applications.
Design
Please refer to the design for more information.
Using libnetwork
There are many networking solutions available to suit a broad range of use-cases. libnetwork uses a driver / plugin model to support all of these solutions while abstracting the complexity of the driver implementations by exposing a simple and consistent Network Model to users.
