About Traefik
Traefik is the cloud-native edge router — automatic service discovery for Docker and Kubernetes, automatic SSL via Let''s Encrypt, and a dashboard UI. 47,000+ GitHub stars.
Traefik vs Nginx: Nginx requires manual configuration for every service. Traefik discovers services automatically via Docker labels or Kubernetes annotations — no config reload required when services change.
Docker integration: add `traefik.http.routers.myapp.rule=Host('myapp.com')` as a Docker label and Traefik automatically routes traffic, provisions an SSL certificate, and handles Let''s Encrypt renewal — zero manual config.
Kubernetes Ingress: Traefik serves as the Kubernetes Ingress controller. Define ingress resources and Traefik handles SSL termination, routing, and load balancing automatically.
Middleware: rate limiting, authentication, circuit breakers, and retry logic as composable middleware.
Key Features
-
●
Automatic discovery: Docker labels and Kubernetes annotations configure routing automatically
-
●
Let''s Encrypt: automatic SSL certificate provisioning and renewal for all domains
-
●
Middleware: rate limiting, auth, retry, and circuit breaker as composable middleware
-
●
Dashboard: real-time visualization of all routes, services, middleware, and health
-
●
TCP/UDP routing: route non-HTTP traffic alongside HTTP in the same Traefik instance
Pros
- ✓Automatic service discovery: Docker labels and Kubernetes annotations configure Traefik automatically
- ✓Zero-downtime reloads: Traefik reconfigures when services start/stop with no manual reload
- ✓Automatic SSL with Let''s Encrypt — no certbot, no cron jobs, no manual cert management
- ✓Dashboard: visual UI showing all routes, services, and middleware in real-time
