Heroku Rocket Minimal Example

Description

A minimal example to deploy a rocket server on heroku

Steps if you want to start from scratch

Initializing an heroku project using rust

1. Create a rust project and commit it to git. cargo init git init
2. Create an app on heroku with heroku create --buildpack emk/rust your-app
3. Create a Procfile and add this line to it web: ./target/release/your-rust-app-name. E.g for this project web: ./target/release/heroku-rocket-minimal-example
4. Push your app to heroku: git push heroku master
5. Check the logs with heroku logs. You should see an "Hello, World!". Great, the rust buildback is correctly building the project and running it.

Adding a minimal rocket server

1. Add rocket as a dependency to your Cargo.toml file rocket = "0.5.0-rc.2"
2. Add routes to you project. See the main.rs for an example.
3. Be careful, you will need to bind to the port provided by Heroku thanks to env PORT and listen to bind to host 0.0.0.0 (localhost won't work)
4. Deploy to heroku, wait a looooong time for the crates to compile.
5. Go to you website adress, and you shoud get a 200 response with a welcoming message.
6. If it goes wrong, you can check the logs with heroku logs --tail
