Getting started

Once installed, you'll have access to the heroku command from your command shell. Log in using the email address and password you used when creating your Heroku account:

$ heroku login
Enter your Heroku credentials.
Email: [e-mail]
Password:
Could not find an existing public key.
Would you like to generate one? [Yn]
Generating new SSH public key.
Uploading ssh public key /Users/adam/.ssh/id_rsa.pub

You're now ready to create your first Heroku app:

$ cd ~/myapp
$ heroku create
Creating stark-fog-398... done, stack is cedar
stark-fog-398.herokuapp.com/ | [e-mail]:stark-fog-398.git
Git remote heroku added

Staying up to date

To keep your heroku client updated, simply run heroku update

$ heroku update
-----> Updating to latest client... done

Creating Apps from the CLI

Last Updated: 03 July 2012

The app is the fundamental unit of organization on Heroku. Users can create an unlimited number of apps; each of which can provision their own add-ons.
Creating a Named App

After creating an app, you will probably want to git push to deploy and add collaborators so that others can deploy changes as well.

To create a new app named “myapp”, install the Heroku Toolbelt and run the following command:

$ heroku apps:create myapp
Creating myapp... done, stack is cedar
myapp.herokuapp.com/ | [e-mail]:myapp.git

The command’s output shows that the app will be available at myapp.heroku.com. The second URL, [e-mail]:high-sunrise-58.git, is the remote git repository URL; by default, the heroku create command automatically adds a git remote named “heroku” pointing at this URL.

To create an app on the Bamboo stack, use the --stack parameter:

$ heroku apps:create myapp --stack bamboo
Creating myapp... done, stack is bamboo-mri-1.9.2
myapp.heroku.com/ | [e-mail]:myapp.git

Creating an App Without a Name

The app name argument (“myapp”) is optional. If no app name is specified, a random name will be generated.

$ heroku apps:create
Created mystic-wind-83.heroku.com/ | [e-mail]:mystic-wind-83.git

Since Heroku app names are in a global namespace, you can expect that common names, like “blog” or “wiki”, will already be taken. It’s often easier to start with a default name and rename the app later.
Welcome Page

Once your new app is created, before any code has been deployed, Heroku will display a generic welcome message to its visitors. This page is served with HTTP status code 502 to indicate that the app is not yet running.
