The right port number for Heroku?

[aliane abdelouahab]

hi,

i have finally (after a big struggle) deployed the application on Heroku, (that happened on OpenSuse because on windows it was a mess -_- ), but now Heroku hates my application, because for him, it is so slow to start:

2014-07-07T21:17:29.728450+00:00 heroku[web.1]: Process exited with status 137

is there any hack to espetially upload an application on Heroku?

here is the code: is use the 8000, and i guess they bind a port from their numbers?

I found this:

http://jamesmcfadden.co.uk/heroku-web-process-failed-to-bind-to-port-within-60-seconds-of-launch/

on Node.js they put :

var port = process.env.PORT || 5000;

so how to make this hack on Tornado?

If you're using tornado.options, the simplest way is to add "--port=$PORT" to your Procfile, as seen here: https://devcenter.heroku.com/articles/procfile#process-types-as-templates.  Otherwise, you can use `app.listen(int(os.environ.get('PORT', '5000')))`.

I think i will forget Heroku :D

i tried it on CloudControl and it works! without any break head :D

In heroku they make port number make available by env variables $port. and also you need have to have a 'procfile' where you would mention how the app is run. In that you can run it via a port. 

sample procfile: 

web: python main.py --port=$PORT

if you want example of deploying a Tornado app in Heroku, here you go: https://github.com/avinassh/heroku-tornado-starter and that of openshift: https://github.com/avinassh/openshift-tornado-starter

i tried CloudControl and i liked it, what i like espetially that i dont have to recompile the whole image when i make changes on code, it only compile what it has to do.

i like it!
