I just installed Heroku toolbelt in a build container. That's how it looks in my build:
sudo: required
before_script:
# this install.sh script requires sudo
- wget -qO- https://toolbelt.heroku.com/install.sh | sh
script:
- /usr/local/heroku/bin/heroku restart --app my-heroku-app-name # requires HEROKU_API_KEY env variable
Note: installing Heroku requires sudo privilege (sudo: required
) and if you have to access your app - $HEROKU_API_KEY
environment variable must be set.
