SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Traefik v3 configuration and best practices for entrypoints, routers, services, and middlewares, including file vs Docker providers, ACME resolvers, wildcard certificates, and dashboard security.

Core Features & Use Cases

  • Understand Traefik concepts: entrypoints, routers, middlewares, and services.
  • Compare static vs dynamic configuration: file provider vs Docker provider, TLS options, and ACME setup.
  • Apply security best practices: protecting the dashboard and safe deployment patterns.

Quick Start

Create a minimal Traefik v3 setup with a static entrypoint and a file-based router.

FAQPage Schema
How do I configure a Traefik v3 reverse proxy with Docker and file providers?

To configure a Traefik v3 reverse proxy, you define static entrypoints and dynamic routers, services, and middlewares using either Docker labels or a file provider. This setup lets you route traffic to containers while enforcing security rules and TLS.

What is the difference between static and dynamic configuration in Traefik?

Static configuration in Traefik defines entrypoints, providers, and ACME resolvers at startup, while dynamic configuration handles routers, middlewares, and services that update at runtime. Separating them ensures safe deployments and proper TLS handling.

How do I secure Traefik dashboard access and set up TLS with ACME resolvers?

To secure a Traefik dashboard and set up TLS, configure ACME resolvers for certificate generation and apply middlewares like basic auth or IP allowlisting to the dashboard router. This prevents unauthorized access and encrypts traffic.

Can I use Traefik v3 for wildcard certificates and automatic HTTPS?

Yes, Traefik v3 supports wildcard certificates and automatic HTTPS through ACME resolvers. You configure DNS challenges in your static configuration to generate wildcard certificates for your domains dynamically.

What's the best way to apply middlewares for routing and security hardening in Traefik?

The best way to apply middlewares for routing and security hardening in Traefik is by chaining them in dynamic configuration files or Docker labels. This enforces TLS redirects, rate limiting, and authentication rules on specific routers.

Why is my Traefik router not working with the Docker provider?

A Traefik router may not work with the Docker provider if dynamic configuration labels are incorrectly applied or the static provider configuration lacks proper network access. Verify container labels and ensure Traefik can reach the Docker socket.
