From version 2.5 of Traefik, you are now able to use HTTP/3 (QUIC). Keep in mind that this protocol is not production-ready and can lead to some instabilities.

Goal : Give the capability for Traefik to receive/send HTTP/3 requests
Environment : Debian 11.2 (bullseye), Docker 20.10.x, docker-compose 2.4.x, Traefik 2.6
Principe and requirements
HTTP/3 is a new web standard to increase the navigation speed. Without going into details, it is a transport protocol to send HTTP requests faster than HTTP/2 (TCP), particularly with the use of UDP.
More information here :
Traefik configuration
Before you start configuring HTTP/3, be aware that it is not possible to let Traefik listen to the same UDP port and TCP port. In addition, the entry point used for HTTP/3 needs to be the same they use with the routers which have a TLS configuration.
Configuration is simple: add the bloc "experimental" and modify the entry point which have the HTTPS bloc:
experimental:
http3: true
entryPoints:
web:
address: ":80"
http:
redirections:
entryPoint:
to: websecure
scheme: https
websecure:
address: ":443"
http3:
advertisedPort: "443"
You have to restart Traefik to commit changes. With this configuration, every router with the entry point "websecure" (in this example) will be reachable in HTTP/2 and HTTP/3.
