Last week I mentioned how I had successfully deployed Nancy / Mono (C# frameworks) onto Heroku. This post covers how you can deploy your own Mono projects onto Heroku.As before, this approach is completely unsupported by Heroku and I'm not 100% sure if it's production ready. I would love to hear your experiences. 0) Prerequisites
There are a few requirements before deploying a project.
- The solution can compile using Mono on Linux (Ubuntu 10.04 - Lucid Lynx).
- The launch application must be a self-hosted executable.
- The self-hosted executable must stay alive and not exit. Example: https://github.com/BenHall/nancy-demo-hosting-self/blob/master/src/Program.cs#L20-23 1) Update heroku gem
Before you continue, make sure your running the latest heroku gem as you need the buildpack option which is only supported in later versions. Thanks Andy Pike for pointing this out.$ gem update heroku
2) Listening to Heroku requests
This is the only part which I'm not too happy with. In order for Mono to accept Heroku requests, you need to bind the listener to the full hostname provided by Heroku - for example http://deep-moon-1452.herokuapp.com. The application also needs to listen on a particular port randomly defined by Heroku. This is provided via an environment variable. Example:
