Heroku CLI Login: An Introduction with Code Examples

Heroku is a popular cloud platform that provides a convenient and simple way to deploy, manage, and scale web applications. One of the key features of Heroku is its command-line interface (CLI), which enables developers to interact with the Heroku platform directly from the terminal. The Heroku CLI provides a variety of commands that allow you to perform various tasks, such as creating and managing apps, scaling dynos, and running one-off commands.

In this article, we'll be focusing on the process of logging in to the Heroku CLI. We'll go over the basic steps of the login process and provide code examples to help you get started.

Getting Started

Before you can start using the Heroku CLI, you'll need to install it on your computer. You can find the installation instructions for your specific operating system on the Heroku CLI website.

Once you've installed the Heroku CLI, you can start using it by opening a terminal window. To check if the Heroku CLI is installed and working correctly, you can run the following command:

heroku --version

This command should display the version of the Heroku CLI that you have installed.

Logging in to the Heroku CLI

Before you can use the Heroku CLI to interact with the Heroku platform, you'll need to log in. The login process is simple and straightforward.

To log in to the Heroku CLI, run the following command:

heroku login

This command will prompt you to enter your Heroku credentials (email address and password). Once you've entered your credentials, the Heroku CLI will log you in and provide you with a unique API key that you can use to access the Heroku platform.

Here's an example of the login process:

$ heroku login
Enter your Heroku credentials:
Email: john.doe@example.com
Password (typing will be hidden): 
Authentication successful.

Logging in with a Heroku API Key

In addition to logging in with your email address and password, you can also log in to the Heroku CLI using a Heroku API key. An API key is a unique string of characters that allows you to access the Heroku platform programmatically.

To log in to the Heroku CLI using an API key, run the following command:

heroku login:api -k <API_KEY>

Replace <API_KEY> with the actual API key that you want to use.

Here's an example of the login process using an API key:

$ heroku login:api -k 12345678-1234-1234-1234-123456789abc
Authentication successful.

Logging Out of the Heroku CLI

If you need to log out of the Heroku CLI for any reason, you can do so by running the following command:

heroku logout

This command will log you out of the Heroku CLI and revoke your API key, effectively ending your session.

Heroku CLI: Other Commonly Used Commands

Now that you're familiar with the process of logging in to the Heroku CLI, it's time to dive deeper into the other commands that are available.

Here are some of the most commonly used Heroku CLI commands:

1. heroku create: This command is used to create a new Heroku app. When you run this command, Heroku will automatically generate a unique name for your app, but you can also specify a custom name if you prefer.

$ heroku create
Creating app... done, ⬢ peaceful-cove-12345
https://peaceful-cove-12345.herokuapp.com/ | https://git.heroku.com/peaceful-cove-12345.git

2. heroku apps: This command displays a list of all the apps that you have access to on the Heroku platform.

$ heroku apps
=== My Apps
peaceful-cove-12345
starry-night-67890

3. heroku logs: This command displays the logs for your Heroku app. You can use the logs to troubleshoot any issues with your app, such as crashes or performance problems.

$ heroku logs
2022-12-01T00:00:00.000000+00:00 app[api]: Starting process with command `python app.py`
2022-12-01T00:00:01.000000+00:00 app[web.1]: Listening on http://0.0.0.0:5000

4. heroku run: This command allows you to run one-off commands on your Heroku app. For example, you can use this command to run a database migration or to run a script to populate your database with data.

$ heroku run python manage.py migrate
Running python manage.py migrate on ⬢ peaceful-cove-12345... up, run.1234

5. heroku ps: This command displays information about the dynos that are running for your Heroku app. A dyno is a container that runs your application code.

$ heroku ps
=== web (1X): `python app.py`
web.1: up 2022/12/01 01:00:00 +0000 (~ 2h ago)

These are just a few of the most commonly used Heroku CLI commands. There are many more commands available, and you can find more information about them in the Heroku CLI documentation.

Heroku CLI: Deploying Your App

In addition to managing your Heroku app, the Heroku CLI also provides commands for deploying your app.

To deploy your app to Heroku, you'll need to have a Git repository that contains your app's code. You can either create a new Git repository or use an existing one.

Once you have your Git repository set up, you can use the following command to deploy your app:

$ git push heroku master

This command will push your code to the Heroku platform, where it will be built and deployed. You can monitor the deployment process by running the heroku logs command.
