Enable use of mongodb with credentials enforced (--auth)

[referup-tarantegui]

A mongodb stack with statsd container attached works fine. But when I'm enabling the use of credentials with --auth in mongodb. The statsd container remains in status restarting, these are the logs:

Can you provide some info for the use of credentials with statsd container.

I've seen that on --help

  -mongo_pass string
        MongoDB Password
  -mongo_user string
        MongoDB User

I'm closing the issue
