# Use GitLab CI/CD to deploy to Heroku
You can deploy an application to Heroku by using GitLab CI/CD.
## Prerequisites
- A [Heroku ](https://id.heroku.com/login ) account.
Sign in with an existing Heroku account or create a new one.
## Deploy to Heroku
1. In Heroku:
1. Create an application and copy the application name.
1. Browse to **Account Settings** and copy the API key.
1. In your GitLab project, create two [variables ](../../ci/variables/index.md ):
- `HEROKU_APP_NAME` for the application name.
- `HEROKU_PRODUCTION_KEY` for the API key
1. Edit your `.gitlab-ci.yml` file to add the Heroku deployment command. This example uses the `dpl` gem for Ruby:
```yaml
heroku_deploy:
stage: production
script:
- gem install dpl
- dpl --provider=heroku --app=$HEROKU_APP_NAME --api-key=$HEROKU_PRODUCTION_KEY
```
