To simplify your workflow, you can edit your Git config to indicate a default Heroku remote.įor example, you can make staging your default Heroku remote with the following command: $ git config heroku.remote staging When a Git repo has more than one associated Heroku remote, the Heroku CLI’s commands require you to specify which app you’re interacting with by including the -r (or -remote) option. Specifying an environment with the Heroku CLI You now have the same codebase running as two separate Heroku apps, one for staging and one for production. You’ll need to add contributors, config vars, buildpacks, and add-ons to each individually, for instance. You will need to do some work to keep these apps in sync as you continue to develop them. Once your staging app is up and running properly, you can create your production environment and push to it with the same commands: $ heroku create -remote production = web: `bundle exec puma -C config/puma.rb`` Therefore, you use the following command to push your code to your app’s new staging environment: $ git push staging master The command above uses the -remote flag to specify a different name for the remote (in this case, staging). You can create a new Heroku app to represent your staging environment with the Heroku CLI: $ heroku create -remote stagingīy default, the Heroku CLI adds a Git remote named heroku to your repo. Let’s say you have an application running on your local (development) machine and you’re ready to push it to Heroku. Creating and linking environments Creating a staging environment Heroku provides helpful tools (namely pipelines, Heroku CI, and review apps) for creating and maintaining your app’s staging and test environments. This means you can’t be sure that the code that works in your local development environment will work exactly the same way in production. This strategy is particularly important because Heroku’s Linux stacks likely differ from your development machine’s operating system. You can help prevent buggy code from being deployed to production by maintaining these separate environments as different Heroku apps, and by using each environment only for its intended purpose. Staging, for running a new build of the app in a production-like setting before promoting it.Test, for running the app’s test suite safely in isolation.Ideally, your app should run in two additional environments: Deployed to the Heroku platform (i.e., production).On your local machine (i.e., development).Your Heroku app runs in at least two environments: Advanced: Linking local branches to remote apps.Managing staging and production configurations.
