Execute a shell script in release phase on Heroku

Question

I have two commands to execute in release phase and as per this tutorial (https://devcenter.heroku.com/articles/release-phase), I have included them in a shell script named release.sh (located in the root of my Django project).

#!/bin/bash

python manage.py migrate
python manage.py compress

In my Procfile, I added the script thus, as described in the article.

release: ./release.sh
web: gunicorn myapp.wsgi --log-file -

But during release I get the following error.

/bin/sh: 1: ./release.sh: not found

Then the release fails.

I don't know if the problem is with the path in Procfile (I also tried bash $PWD/releash.sh) or the file not being available at the time it is called. Any help would be appreciated.

EDIT:

My release.sh was in a subfolder and that's why it wasn't found, but now I'm getting permission denied.

/bin/sh: 1: ./release.sh: Permission denied

Answer 1

This worked

chmod u+x release.sh && ./release.sh

So Procfile becomes

release: chmod u+x release.sh && ./release.sh
web: gunicorn myapp.wsgi --log-file -

Answer 2

For this to work, release.sh must be executable

Locally, you could run chmod a+x release.sh. But you would not want to do that on heroku, so instead you can change the Profile to have this:

release: bash release.sh
web: gunicorn myapp.wsgi --log-file -
