I think a combination of traefik and docker compose are in the sweet spot for small scale self hosters that haven't reached the point where k8s will pay off. i.e. if you have less servers than a k8s HA control plane would use.
We've called it "tray-feek" and it was half ok, then we actually had a call with the official support and they told us its pronounced same as regular "traffic". So any discussion about that proxy goes with: "so we're receiving traffic on our public load balancer which used traffic's native load balancing to send traffic to traffic's pods...". It sounds stupid because it is stupid.
I wondered how to pronounce Traefik myself, so I started googling, and came across this: https://traefik.io/blog/how-to-pronounce-traefik-d06696a3f02...
Tldr: just pronounce as you would "traffic".
