Heroku Buildpack for Eiffel

A Buildpack that allows you to deploy Eiffel applications on the Heroku platform.

Status

• Working for repositories with multiple, multi-target ECFs
• Only builds libraries for ODBC

Notes

• A Procfile is required for execution. Make sure the application accepts the $PORT argument for HTTP routing.
• Use the nino server to provide HTTP access.

Todo

• There is currently no accommodation for Heroku addons.

Credits

• Heroku and their new Buildpack-capable stack

Usage

Set the buildpack for the project

$ heroku config:set BUILDPACK_URL=https://github.com/mbustosorg/heroku-buildpack-eiffel

The buildpack will select and build the first ECF and target found in the repository. You can set a specific ECF and target if you wish by setting the $EC_CONFIG and $EC_TARGET variables.

$ heroku config:set EC_CONFIG=restbucks-safe.ecf
$ heroku config:set EC_TARGET=restbucks

Push the app to Heroku. Learn more about deploying to Heroku with git.

$ git push heroku master
