Traefik is a modern, cloud-native edge router that automates and simplifies routing to your services. It is designed to be easily configured and dynamically adapt to your infrastructure. It automatically discovers the appropriate configuration for your services and routes traffic to them. Traefik natively supports multiple orchestration systems like Kubernetes, Docker, Docker Swarm, Mesos/Marathon, Consul, Etcd, Rancher, and more. It is designed to be a *dynamic* proxy, constantly monitoring your infrastructure for changes and automatically updating its configuration. Traefik offers advanced features like automatic TLS certificate generation using Let's Encrypt, circuit breakers, health checks, metrics integration (Prometheus, Datadog, StatsD), request tracing, and more. It provides a user-friendly dashboard for monitoring the health and status of your services and the Traefik instance itself. Traefik can be used in various scenarios, from simple local development setups to complex production environments.

Configuration is complex and often requires understanding of the underlying infrastructure being integrated with. Debugging misconfigurations can be challenging without proper logging and monitoring.

Traefik's dynamic configuration capabilities are a core feature. It automatically discovers and updates its routing configuration based on changes in your infrastructure (e.g., new containers being deployed, services scaling up or down). This eliminates the need for manual configuration and restarts, making it ideal for dynamic environments.

Traefik simplifies TLS configuration by automatically generating and renewing certificates using Let's Encrypt. It also provides various security features, such as rate limiting, authentication middleware, and HTTP to HTTPS redirection.

Traefik was originally created by Emile Vauge.
It quickly gained popularity due to its ease of use, automatic configuration, and support for various orchestration systems. Traefik has evolved through multiple major versions, with significant improvements in performance, features, and stability. Its development is driven by the open-source community and commercial support is available.
