Description

It seems it's not possible to map a single container port to multiple host ports when using host mode. It might be similar to this issue: docker/compose-cli#1655

Reproduce

  1. create a compose file foo.yml
version: "3.4"

services:
  nginx:
    image: nginx
    ports:
      - target: 80
        published: 7500
        protocol: tcp
        mode: host
      - target: 80
        published: 7501
        protocol: tcp
        mode: host
      - target: 90
        published: 7502
        protocol: tcp
        mode: host
  1. deploy the services
docker stack deploy -c foo.yml foo
  1. inspect the service
docker ps | grep foo

example output with the 7500 mapping missing

e52e785d43ab   nginx:latest "/docker-entrypoint.…"   3 minutes ago Up 3 minutes 0.0.0.0:7501->80/tcp, :::7501->80/tcp, 0.0.0.0:7502->90/tcp, :::7502->90/tcp   foo_nginx.1.ynapf1jho2sg2jib4391j1tej

Expected behavior

Both ports 7500 and 7501 should have been mapped, but only the last one was.
