How to update an Heroku App created using GitHub "Deploy to Heroku" button?

I've created an app using a GitHub 'Deploy to Heroku' button. Since the git project has changed, how to update my existing instance with new upstream commits?

Solution

  • I went and grabbed the original repo and then force pushed it onto my app in Heroku. Looks like this:

    git clone https://github.com/USER/REPO.git
git checkout v0.7.3
git remote add heroku https://git.heroku.com/APP-NAME.git
git push -f heroku master

    Heroku makes it easy to clone the repo for you app using

    heroku git:clone -a app-name

    I originally tried doing that and then adding the original repo as a remote and merging changes, but I ran into some trouble which I didn't feel like figuring out.
