The Auth0 blog has posted the third part of their "Building a Blog" series of tutorials showing the use of their authentication technologies coupled with a Symfony framework backend. In this latest article author Greg Holmes shows how to deploy the application created in parts one and two to Heroku.

Symfony is a PHP framework as well as a set of reusable PHP components and libraries. It uses the Model-View-Controller design pattern and can be scaled to be used in any requirement. It aims to speed up the creation and maintenance of web applications, replacing repetitive code. In this part of the series, you will learn how to deploy the blog engine that you have created in the previous parts on Heroku. The final code can be found at this repository.

He starts with a bit of catching up, briefly covering the contents of the first two articles before getting into the main content of this third. He covers some of the basics of Heroku and Travis-CI before getting into the actual deployment flow. He then helps you set up a GitHub account (used as a source for the deployment), set up a local MySQL database for testing and the installation of a few required dependencies. Next is the installation of the Heroku and Travis-CI command line tools, the configuration for each and some basic setup steps for each service.

Finally, he gets back to the Symfony application, setting up a few additional options in the Composer configuration to create a few commands. These commands are then executed as a part of the deployment process. There's also changes to the Symfony configuration files to reference the environment rather than a local path in several locations. The post ends with the setup instructions on the Auth0 side to allow handling to work from the newly deployed Heroku instance.
