You can use service links, this enable the following environment variables inside ui containers: (assuming your exposed port is 6800)

  ui:
    image: 'ui'
    ports:
      - target: 6801
        published: 6801
        protocol: tcp
        mode: host 
    environment:
      - 'SERVER=http://backend-service:6800'
      - HOST=0.0.0.0
    deploy:
      mode: global
    links:
      - backend-service:backend

You can use network strategy too: https://docs.docker.com/engine/swarm/networking/
