Calico with Docker
Calico implements a Docker network plugin that can be used to provide routing and advanced network policy for Docker containers.

Quickstart with “Calico-Ready” Clusters
Follow this guide to launch a local 2-node CoreOS Container Linux cluster with everything you need to install and use Calico.
Follow this guide to launch a local 2-node Ubuntu cluster with everything you need to install and use Calico.
The above guide demonstrates Calico connectivity cross host, and how to limit that connectivity using simple Calico profiles. One profile is created for each network and the connectivity is defined as policy on each profile.
The above guide digs deeper into advanced policy configurations for workloads. There is still one profile created for each network but now the profiles define labels that are inherited by each container added to the network. The policy uses the labels in selectors to configure connectivity.
The above guide demonstrates Calico connectivity between containers without using Profiles at all. Instead, Calico policies are defined which apply to containers depending on the labels assigned to them at runtime. This allows policy adjustment at the container level rather than at the network level.
This guide walks through configuring a Docker network for use with Calico and how to statically assign IP addresses from that network
