connect to localhost port inside the docker container is refused

Docker version 17.12.0-ce, build c97c6d6

OS: Debian GNU/Linux 9 (stretch)

It's my Dockerfile:

FROM ubuntu:14.04

EXPOSE 5432

build the container:

 $ docker build -t expose_5432_port .

run the container:

docker run -ti expose_5432_port /bin/bash

I try to connect the port inside the container:

root@5f15a7ebd280:/# nc -v -z 127.0.0.1 5432
nc: connect to 127.0.0.1 port 5432 (tcp) failed: Connection refused

How to connect the port?

This is expected.

EXPOSE opens a way to connect to port 5432 in the container but as it states connect to 127.0.0.1 port 5432 (tcp) failed: Connection refused, you are able to connect/reach to the port successfully but since there is nothing running on that port it's saying connection refused. You got to make some application run on port 5432.
