LEARN BY DOING

Use cases & applications

Reverse Proxy for Docker

Automatically expose Docker containers as web services with domain names, without any restarts.

Ingress Controller for Kubernetes

Dynamically manage a Kubernetes cluster's incoming traffic based on Ingress resources or CRDs.

Load Balancing

Distribute load across several instances (replicas) of the same application for high availability.

Frequently asked questions

What is Traefik?

What's the difference between Traefik v1 and v2?

v2 introduced the concepts of Routers, Middlewares and Services, offering a more flexible and powerful configuration than v1's frontends/backends.
