I need to connect to an API with my Heroku/Rails app where I need to have a static IP.
I know about the add-on proximo - https://devcenter.heroku.com/articles/proximo - but it is insanely priced, so that's out of the question.
Most people in my situation ends up deploying to EC2 instead and using a an Elastic IP as their static IP. I've also tried this and it works, but I find the whole flow of playing around with EC2 really cumbersome.
I've read in some answers that it is possible to set up an EC2 server and use it as a proxy for your Heroku/Rails app - Heroku Static IP for SFTP - but it sounds very cryptic for a person who is not very server-savvy.
Can someone give a step-to-step tutorial on how to set up your Heroku/Rails app to use your EC2 instance as a proxy?
