Why does pushing my locally created MEAN-Application to OpenShift not work?

Question

I'm trying to push my MEAN-Application, which I created locally using express, to OpenShift. For that, I create a new application from the dashboard and add NodeJS as a cartridge. When I then add my Git-Repository-URL (Hosted on BitBucket) and create the application, I get the following error:

When I create a new application without entering the repository URL and then pull from Openshift, copy in my Project and Push again, I get a similar error:

It seems to be some problem with port 8080 being unavailable but I cant resolve this myself as I'm new to this and couldn't find a solution on the web, so any help & advice is appreciated.

EDIT: when I say MEAN I actually mean EAN; I don't use MongoDB at the moment.

EDIT 2: after several hours I decided to try Heroku. It also didn't work on the first try but the Log contained far more useful information so I got everything up and running in about an hour (compared to like 4 hours of trying with OpenShift). After that I tried to push the exact same Project I pushed to Heroku to Openshift and got the following, new error:

Again, if somebody happens to know a quick fix for this please tell me as I would still like to use OpenShift.

Answer 1

What worked for me was the following:

1. Create App on OpenSHift, leave Repo Url empty for now.
2. Use git remote add openshift -f <openshift-git-repo-url (ssh://...something)> to add the Openshift-Repo as a remote Repo to your Project.
3. Use git merge openshift/master -s recursive -X ours to merge the Openshift-Repo into your local Repo and keep your files if conflicts appear.

4. (And this is the important step) Your main File (bin/www for me) has to look something like this (I tried everything to format this but it just didn't format properly):

   var app = require('../app'); var debug = require('debug')('CTW:server'); var http = require('http');

   /**

   • Get port from environment and store in Express. */ app.set('port', process.env.OPENSHIFT_NODEJS_PORT || process.env.PORT || 3002); app.set('ip', process.env.OPENSHIFT_NODEJS_IP || "127.0.0.1");

   /**

   • Create HTTP server. */

   var server = http.createServer(app);

   /**

   • Listen on provided port, on all network interfaces. */

   server.listen(app.get('port') ,app.get('ip'));

5. git push openshift HEAD to push it to your Application Repo

As it turns out, I had to set the IP.

All credit goes to this and this questions answers.

Answer 2

Your NodeJS code should look something like this:

var port = process.env.OPENSHIFT_NODEJS_PORT || 8080;
http.createServer().listen(port);

That will use the value of OPENSHIFT_NODEJS_PORT if it is available, and still use 8080 when you run the application outside of OpenShift. Or you could even set the environment variable OPENSHIFT_NODEJS_PORT=8080 on your local machine to more closely simulate the OpenShift environment.

Note that you should also check the environment variables to get the correct server IP address. See this documentation for more information.
