The Docker Flow Swarm Listener (https://github.com/vfarcic/docker-flow-swarm-listener) project leverages Docker Remote API. It has many usages but, for now, we'll limit ourselves to the features that can help make our proxy configuration fully hands-free.
We'll start by creating two networks:
eval $(docker-machine env swarm-1)
docker network create --driver overlay proxy
docker network create --driver overlay go-demoWe created those two networks so many times that there is no reason to go over their usefulness. The only difference is that this time, we'll have one more service to attach to the proxy network.
Next, we'll create the swarm-listener (https://github.com/vfarcic/docker-flow-swarm-listener) service. It will act as a companion to the Docker Flow Proxy. Its purpose is to monitor Swarm services and send requests to the proxy whenever a service is created or destroyed.
