Non-default http ports

[richardhj]

I must not use the default http ports 80 and 443 (it is preserved by macOS Server). So I've chosen different ports but LetsEncrypt does call port 80: sslproxy_1 | http://example.org/.well-known/acme-challenge/aQUorM87vM7pFCRxidfmFFzs_n_MqODBW2tFivinYhk:

services:
  sslproxy:
    image: danieldent/nginx-ssl-proxy
    restart: always
    environment:
      UPSTREAM: 127.0.0.1:8882
      SERVERNAME: example.org
    ports:
      - "89:80"
      - "442:443"
    volumes:
      - …/docker/nextcloud/nginx-conf:/etc/nginx/conf.d

I realized that the ACME server relies on Port 80 or 443 (or an DNS txt entry). So I'm going to hack the macOS Server apache config in order to free up that ports.
