The goal of the Docker Flow Swarm Listener project is to listen to Docker Swarm events and send requests when a change occurs. At the moment, the only supported option is to send a notification when a new service is created, or an existing service was removed from the cluster. More extensive feature support is coming soon.
Please visit the project documentation for more info or join the #df-swarm-listener Slack channel in DevOps20 if you have any questions, suggestions, or problems.
