Sample Crystal application

Running Locally

First, you need to have a working crystal environment:

http://crystal-lang.org/docs/installation/

You can specify the listening port using the --port flag

Test

crystal src/scalingo01.cr -- --port 9090

Build

crystal build src/scalingo01.cr --release

Execute

./scalingo01 --port 9090

Deploying on Scalingo

Create an application on https://scalingo.com, then:

git remote add scalingo git@scalingo.com:<name_of_your_app>.git

Set the BUILDPACK_URL environement variable to https://github.com/crystal-lang/heroku-buildpack-crystal.git.

You can do it using the web dashboard, select your application, go to the Environment tab and add :

BUILDPACK_URL=https://github.com/crystal-lang/heroku-buildpack-crystal.git

If you want to do it using the scalingo cli interface juste type :

scalingo -a <name_of_your_app> env-set BUILDPACK_URL=https://github.com/crystal-lang/heroku-buildpack-crystal.git

Next you'll need to push it to scalingo :

git push scalingo master

And that's it!

The application is running at this url: https://sample-crystal.scalingo.io

Deploy in one click
