Service starts but not use the port that is specified

[luizbob]

version: "3.4"

services:
  orbiter:
    image: gianarb/orbiter
    ports:
      - 8001:8001
    volumes:
      - /var/run/docker.sock:/var/run/docker.sock
    deploy:
      placement:
        constraints:
          - node.role == manager
      mode: replicated
      replicas: 1

Even if i put the ports diferently, or 8000, this happens

"NetworkSettings": { "Bridge": "", "SandboxID": "589789cd6bdacc517390d98ae5430560b6f1274b84f59b6ecd26ca06dc9d31a6", "HairpinMode": false, "LinkLocalIPv6Address": "", "LinkLocalIPv6PrefixLen": 0, "Ports": {},

And i cannot access the container, the only way that i find for me to use it is following this
