Traefik and Let's Encrypt on non default http port 80?

问题

I tried setting up test container to work with traefik and lets encrypt.

Traefik is not running on default ports 80 and 443.

The server already has apache, reverse proxy ngnix and tomcat locally installed so ports: 80, 443 and 8080 are not available.

As far as I can understand the log, there is a misconfiguration concerning the ACME ports. The test container seems to get correctly wired to the entrypoint.

How do I get lets encrypt and traefik to work in this scenario or did I do something wrong?

My traefik.toml:

debug = true
logLevel = "ERROR"
defaultEntryPoints = ["http", "https"]
[entryPoints]
  [entryPoints.http]
  address = ":50500"
    [entryPoints.http.redirect]
    entryPoint = "https"
  [entryPoints.https]
  address = ":50501"
   [entryPoints.https.tls]
 [accessLog]
[retry]
[web]
address = ":50502"
[docker]
endpoint = "unix:///var/run/docker.sock"
domain = "example.com"
watch = true
exposedbydefault = false
[acme]
email = "me@example.com"
storage = "acme.json"
entryPoint = "https"
OnHostRule = true
[acme.httpChallenge]
entryPoint = "http"

the docker-compose.yml:

version: '2'

services:
  traefik:
    image: traefik:1.5.0
    restart: always
    ports:
      - 50500:50500
      - 50501:50501
      - 50502:50502
    networks:
      - web
    volumes:
      - /var/run/docker.sock:/var/run/docker.sock
      - /home/someuser/traefik/traefik.toml:/traefik.toml
      - /home/someuser/traefik/acme.json:/acme.json
    container_name: traefik

networks:
  web:
    external: true

running docker logs traefik returns:

Let's Encrypt required the port 80 or 443 see https://community.letsencrypt.org/t/support-for-ports-other-than-80-and-443/3419/72
