What problem does it solve?

This Skill enables HTTP/3 (QUIC) support for a Traefik ingress controller in Kubernetes, addressing misconfigured Alt-Svc headers and port exposure.

Core Features & Use Cases

  • Traefik Helm values: configure http3 and set advertisedPort to match the external port to ensure correct Alt-Svc.
  • Service ports & re-rendering: ensure the Traefik service includes a UDP port for websecure-http3 and trigger Helm template re-renders after changes.
  • Cloudflare integration: enable HTTP/3 in Cloudflare for proxied domains and verify end-to-end connectivity.
  • Verification: perform end-to-end checks from the cluster and from external clients to confirm HTTP/3 negotiation and operation.

Quick Start

Apply the Traefik HTTP/3 configuration by enabling http3 in Helm values and re-rendering the release, then verify the Alt-Svc header and UDP port exposure.
