Dynamic Services?

[philippeboyd]

Can it be possible to make it dynamic?
For example :

.....
  data:
    image: mongo:3.4
    networks:
      - mongo
    volumes:
      - data:/data/db
    command: mongod --shardsvr --replSet datars --smallfiles --port 27017
    deploy:
      mode: replicated
      replicas: 3
      placement:
        constraints:
          - node.labels.mongo.role == data

There is no StatefulSets support in Swarm so you can't get a DNS record per Mongo node like you do in Kubernetes. Even if you would query the tasks records in Swarm DNS to get the containers IP, when you restart a container that IP will change and the cluster will get broken.
