Traefik v3, and TCP services in consul service mesh

Traefik Traefik v3 (latest)
1

While in Traefik v2, only HTTP services could be reached when using Traefik native Consul service mesh support, I see that Traefik 3 now has ServersTransport available for TCP (ServersTransport on TCP configurations · Issue #7803 · traefik/traefik · GitHub). But it's unclear if this is sufficient for TCP service to work, or if something else must be done.

I can't seem to have it working for now (no issue for HTTPS, only TCP services in the mesh are problematic)

Anyone has some info on this ?

I finally was able to use native Consul service mesh with TCP services. The key is to ensure Traefik talk to the backend with TLS, like

traefik.tcp.services.postgres.loadbalancer.server.tls=true

This should be done automatically, as it makes no sense to have this to false with the service mesh
