Comment on Multiple Kubernetes Services Using Same Port Without SNI
simonmicro@programming.dev 3 weeks agoAh yes, I see. Because TCP has no SNI built-in this is not really possible.
You could try IPv6, as within even a single /64 routable prefix you can choose the address section freely. Also take a look at overlay-vpn solutions like Netbird: They allow you to offer you multiple clients, which you could use to assign multiple IPv4 to your server and then routing them differently…

I had not thought about using IPv6 for this. It’s definitely something that I would need to research more as I know that this would expose my attack surface and may require an overhaul of the network (or at least a very thorough review).
I’m not sure I understand the concern about Traefik. I am using it as a reverse proxy and forcing HTTPS for all applicable services (which unfortunately does not apply to this particular situation). I am honestly a little confused about the control plane, tls-san, gateway, load balancer, ingress, etc. and how they all work together. I may not be using Traefik as the Load Balancer and instead have Kube-VIP as the LoadBalancer. I did not configure Kube-VIP any particular way for Load Balancing, but I did configure Traefik with a few Load Balancer specific options. When I tried to setup Kube-VIP with the additional IP addresses for load balancing, I was unable to get k3s to work correctly so I assumed that Traefik was my Load Balancer instead of Kube-VIP.
