Is it the correct dockerfile to install centos with mongodb?

[Doppy]

I need to install centos with mongodb and after I must configure nodebb so I create dockerfile:

FROM centos:latest
RUN yum -y update ; yum clean all
RUN yum -y install epel-release tar ; yum clean all
RUN yum -y install wget ; yum clean all
RUN yum -y groupinstall "Development Tools"
RUN yum -y install nodejs git ImageMagick npm
RUN yum -y install openssl openssl-devel


RUN yum -y update; yum clean all
RUN yum -y install mongodb-server; yum clean all
RUN mkdir -p /data/db

RUN cd /opt ; git clone -b v1.2.1 https://github.com/NodeBB/NodeBB nodebb
RUN cd /opt/nodebb ; npm install
VOLUME /opt/nodebb

# Define a working directory
WORKDIR /opt/nodebb

# Expose ports
EXPOSE 80
EXPOSE 443
EXPOSE 4567
EXPOSE 27017

CMD [ "node", "app.js" ]

After that I do

sudo docker build -t centos .

I do:

 sudo docker run -i -t centos /bin/bash

I go in the correct folder and I do
./nodebb setup
I put all parameter but at the end of process I obtain

 NodeBB could not connect to your Mongo database. Mongo returned the following error: connect ECONNREFUSED 127.0.0.1:27017
5/4 12:34 [20] - warn: NodeBB Setup Aborted.

Anyone can help me?

@Doppy This is not how you're supposed to use Docker.
One process should run per container so one for mongo (use the mongodb image) and one for nodebb.
You would link the nodebb one to the mongo one and you're done.

@Telokis and after that I have created two containers How can I do? I must mount some volumes?

Take a look at my image here : https://hub.docker.com/r/ninetainedo/nodebb/
