Testing provenance service in a distributed environment

[jkesanie]

Description

Testing provenance service in Kontena cloud and cPouta (Swarm). Run mock message provider and provenance service in order to test HA capabilities of platforms and the message persistance.

For example: Is the infra able to automatically start up a new instance of ProvService if we delete the old container manually? Are the messages sent during the absence of the service preserved? Load balancing?

@jkesanie @joasilva provenance image for testing purposes pushed to private repo attx-dev:5000/prov-service:dev (it has a hard requirement that the messaging service name be messagingservice, we can add it as a parameter later, for now it will remain like that). and docker-compose file available below. I am using version 3 because there is a need for depends_on parameter (maybe there is another way to make it work) in order for the provservice and rmlservice to start after the messagebroker.

version: '3'
services:
  messagebroker:
    image: attx-dev:5000/mom:latest
    ports:
      - '8161:8161'
      - '61616:61616'
      - '5672:5672'
      - '61613:61613'
      - '1883:1883'
      - '61614:61614'
  rmlservice:
    image: attx-dev:5000/rml-service:dev
    depends_on:
        - messagebroker
    environment:
        - BROKER_URL=tcp://messagebroker:61616
    links:
      - messagebroker:messagebroker
  provservice:
    image: attx-dev:5000/prov-service:dev
    depends_on:
        - messagebroker
        - rmlservice
    links:
      - rmlservice:rmlservice
      - messagebroker:messagebroker

The whole setup currently might be missing something because, even though the services connect to the messagebroker, provservice is not receiving any messages from rmlservice or no messages are sent - @jkesanie ideas ? (tried sending a message from the UI - the provservice receives it and does its thing).
