Unable to connect to mongodb using URL using monstache

Question

I've been trying to synchronize my mongodb with elastic for two days and I'm going crazy. After many attempts and changes in my dockerfile and in my docker-compose I get this error, but the container with mongodb is up and running.

monstache        | ERROR 2018/07/27 17:59:07 Unable to connect to mongodb using URL 'mongodb:27018': no reachable servers
monstache        | panic: Unable to connect to mongodb using URL 'mongodb:27018': no reachable servers
monstache        | 
monstache        | goroutine 1 [running]:
monstache        | log.(*Logger).Panicf(0xc420020c30, 0xd4fc15, 0x2d, 0xc42006fc18, 0x2, 0x2)
monstache        |  /usr/local/go/src/log/log.go:219 +0xdb
monstache        | main.main()
monstache        |  /home/vagrant/go/src/github.com/rwynn/monstache/monstache.go:2400 +0x320
monstache exited with code 2

This is my dockerfile

FROM golang
ADD build-4.4.0/linux-amd64/monstache /go/bin/monstache
ENTRYPOINT ["monstache", "-mongo-url='mongodb:27018'", "-elasticsearch-url=elasticsearch:9200"]

And this is my docker-compose file

version: '3.3'
services:

  mongodb:
    image: mongo
    restart: always 
    container_name: mongodb
    volumes:
      - ./data/mongodb:/usr/share/mongodb/data
    ports:
      - 27018:27017

  elasticsearch:
    image: elasticsearch
    restart: always
    container_name: elasticsearch
    volumes:
      - ./data/elastic:/usr/share/elasticsearch/data
    ports:
      - 9200:9200

  monstache:
    build: ./monstache/
    restart: always
    container_name: monstache
    links:
      - elasticsearch
      - mongodb

Any idea?

Thanks!

Finally, we desist to use monstache, and we use mongo-connector in a python dockerfile to share the data from mongodb to elasticsearch.

FROM python:3.4.3

RUN pip install 'mongo-connector[elastic5]' && \
  pip install 'elastic2-doc-manager[elastic5]'

I hope this can help to someone.
