docker stack network issue

i have crated the docker stack file as below, it created the 3 services, as excepted but i am unable to access out side of the host. and its not creating any port also. i have created a overlay network called test01. When i create a this manually via command line it works perfectly. 

version: '3.0'
networks:
 default:
  external:
   name: test01
services:
 mssql:
  image: microsoft/mssql-server-windows-developer
  environment:
   - SA_PASSWORD=Password1
   - ACCEPT_EULA=Y
  ports:
   - 1433:1433
  volumes:
   - c:\Databases:c:\Databases
  deploy:
   placement:
    constraints: [node.labels.os==Windows]
 web:
  image: iiswithdb:latest
  ports:
   - 8080:8080
  deploy:
   replicas: 3
 lbs: 
  image: nginx:latest
  ports:
   - 80: 80
  deploy:
   placement:
    constraints: [node.labels.os==Windows]

Your services need to explicitly join the network you are defining. You can do this in the compose file. Otherwise they will use the default network created by the stack/compose. https://docs.docker.com/compose/compose-file/#networks
