What problem does it solve?

Traefik evolves rapidly after model training cutoffs, introducing breaking changes, renamed fields, new routing and load-balancing behaviors, and security options that can break existing configurations or expose services. This Skill consolidates those changes into concise guidance so engineers avoid outdated patterns and misconfigurations when authoring or upgrading Traefik deployments.

Core Features & Use Cases

• Version Coverage: Tracks changes from Traefik v3.1 through v3.6.9 including deprecations and renamed fields required for correct configuration.
• Routing & Middleware Guidance: Explains multi-layer routing (parentRefs), ForwardAuth enhancements (body/method forwarding), compression encodings, error page rewrites, path sanitization, and encoded-character controls.
• Load Balancing & Scale: Documents new LB strategies (p2c, leasttime, highestRandomWeight), TCP/passive health checks, sticky cookie options, fast proxy mode, and Redis-backed distributed rate limiting.
• Providers & Observability: Covers Knative and NGINX Ingress providers, OTLP logging, trace verbosity, dashboard base path, and post-quantum TLS curve options.
• Use Case: When migrating a cluster to Traefik v3.6, use this patch to update router rules, enable Redis rate limiting for multi-instance deployments, and adopt the recommended LB strategy without introducing downtime.
