> And no - you don't need an ingress. Just spin up a nodeport service, and you have the literal identical experience to exposing ports with compose - it's just a port on the machines running the cluster (any of them - magic!).

Might need to redefine the port range from 30000-32767. Actually, if you want to avoid the ingress abstraction and maybe want to run a regular web server container of your choice to act as it (maybe you just prefer a config file, maybe that's what your legacy software is built around, maybe you need/prefer Apache2, go figure), you'd probably want to be able to run it on 80 and 443. Or 3000 or 8080 for some other software, out of convenience and simplicity.

Depending on what kind of K8s distro you use, thankfully not insanely hard to change though: https://docs.k3s.io/cli/server#networking But again, that's kind of going against the grain.
