%description
Traefik (pronounced traffic) is a modern HTTP reverse proxy and load balancer
that makes deploying microservices easy. Traefik integrates with your existing
infrastructure components (Docker, Swarm mode, Kubernetes, Marathon, Consul,
Etcd, Rancher, Amazon ECS) and configures itself automatically and dynamically.

Pointing Traefik at your orchestrator should be the only configuration step you need.
