  image: xyz/a:dev
  ports:
   - "80:80"
   - "443:443"
  networks:
   -my_network
b:
  image: xyz/b:dev
  ports:
  - "5000:5000"
  networks:
   -my_network

networks:
  my_network:
    driver:overlay
    ipam: 
     driver: default
     config:

Example of how to specify port ranges:

ports:
  - "9090-9091:8080-8081"

The long form allows specifying the mode as either host or ingress.

ports:
  - target: 80
    host_ip: 127.0.0.1
    published: 8080
    protocol: tcp
    mode: ingress

See the Ports section of the docker-compose spec for more details.

The ingress network is only for manager/worker nodes.

The routing mesh routes all incoming requests to published ports on available nodes to an active container. https://docs.docker.com/engine/swarm/ingress/

What you want is an addition overlay network. All services which are assigned to the same overlay network which is not ingress, can talk to each other over the name you've given them.

E.g.

docker service create --name A --network dev ...
docker service create --name B --network dev ...

Service A can simply do ping B.

Apparently, these options are not exposed in the composefile. The documentation doesn't mention them and to be sure you can check the source code, in particular the latest compose schema.

The only option is to create the ingress network on the command line and reference it from the compose file as an external network.
