All true.

Ah okay. You need some sort of reverse proxy.
I really like caddy. Using it with caddy-docker-proxy in docker-compose makes it quite nifty:

version: '3.7'
services:
  whoami:
    image: containous/whoami
    networks:
      - caddy
    labels:
      caddy: http://whoami.mylab.home
      caddy.reverse_proxy: "{{upstreams 80}}"

networks:
  caddy:
    external: true

Just make sure to explicitly use ‘http’ instead of ‘https’. That way it won’t try to create certificates.
