This is an example of how to set up a Leaf PHP application to deploy on Kinsta’s Application Hosting services from a GitHub repository.

Leaf is a slim and lightweight PHP framework focused on developer experience, usability, and high-performance code. More information is available on the Leaf PHP website.

Kinsta automatically installs dependencies defined in your composer.json file during the deployment process.

  1. Log in to GitHub and create a new repository from this template (Use this template > Create a new repository): Kinsta – Hello World – Leaf PHP.
  2. In MyKinsta, add an application with the Hello World – Leaf PHP repository. The Start command can be left blank for the web process as Kinsta automatically detects the required command during the first deployment.

The app is available as soon as the build finishes, and the Kinsta Welcome page loads at your application’s URL.

Web Server Setup


Kinsta automatically sets the PORT environment variable. You should not define it yourself, and you should not hard-code it into the application.

Start Command

When deploying the application, Kinsta automatically creates a web process running heroku-php-apache2.

Deployment Lifecycle

Whenever a deployment is initiated (through creating an application or redeploying due to an incoming commit), the composer install command is run.
