TCP packets don't include host information (unless you're capitalizing on SNI when using TLS), so in the context of an entryPoint in Traefik, what does host mean? Is it only applicable for HTTP(S)?
The documentation doesn't go into detail:
The address defines the port, and optionally the hostname, on which to listen for incoming connections and packets. It also defines the protocol to use (TCP or UDP). If no protocol is specified, the default is TCP. The format is:
[host]:port[/tcp|/udp]
As far as I'm aware, routing is defined via Ingress, IngressRoute and IngressRouteTCP, so I imagine this host in this context is not used for routing, and is perhaps metadata for us?
