Dear @mlocher, could you update the script to reflect the current Codeship settings.
Specially about the use of "heroku run" instead of the "heroku_run" wrapper.
As stated in https://codeship.com/documentation/continuous-deployment/deployment-to-heroku/#run-commands-on-heroku

This script doesn't reflect the integrated Heroku deployment on Codeship (as we do not support maintenance mode in the integrated deployment). It is based on the integrated deployment though and matches it closely.

For an up to date version, please use the integrated Heroku deployment, which is maintained by the Codeship team. This script is unsupported and won't be updated with changes made to the integrated deployment. It was (is) provided as a starting point, but was never expected to be maintained by us (that's why it was released to my private account and not an official Codeship account).

Thanks for answering @mlocher!

I still "need" maintenance mode, so I'll have to keep using the script.

To "update" the script, simply replace all occurrences of heroku_run ${COMMAND} ${APPLICATION_NAME} with the following command.

heroku run --exit-code --app ${APPLICATION_NAME} -- ${COMMAND}

So heroku_run rake db:migrate "testapp" would get translated to heroku run --exit-code --app testapp -- rake db:migrate

Changes to the Heroku CLI made it possible to return the exit code directly and made the wrapper obsolete. (The wrapper is still available and basically translates the commands you pass to it into the above template. See the documentation article you linked to for all the details.)

Thank you very much @mlocher! I'll update the script.
