Traefik tutorial

Traefik automaticky detekuje služby z Dockeru a Kubernetes.

Proč Traefik¶

• Auto-discovery (Docker, K8s, Consul)
• Automatické SSL (Let’s Encrypt)
• Dashboard
• Middleware (auth, rate limit)

Docker setup¶

services: traefik: image: traefik:v3.0 command: - –providers.docker=true - –entrypoints.web.address=:80 - –certificatesresolvers.le.acme.httpchallenge.entrypoint=web ports: [‘80:80’, ‘443:443’] volumes: [‘/var/run/docker.sock:/var/run/docker.sock:ro’] webapp: image: myapp labels: - traefik.http.routers.webapp.rule=Host(app.example.com) - traefik.http.routers.webapp.tls.certresolver=le

Middleware¶

labels: - traefik.http.middlewares.rl.ratelimit.average=100 - traefik.http.routers.webapp.middlewares=rl

Traefik pro Docker/K8s¶

Auto-discovery + auto SSL = ideální pro cloud-native.
