|
|
|
+
|
|
|
+<blockquote><em>Traefik (pronounced traffic) is a modern HTTP reverse proxy and load balancer that makes deploying microservices easy. Traefik integrates with your existing infrastructure components [...] and configures itself automatically and dynamically. Pointing Traefik at your orchestrator should be the only configuration step you need. -<a href="https://github.com/traefik/traefik" target="_blank">https://github.com/traefik/traefik</a></em></blockquote>
