Our application is almost ready and it's time to go into production. Since this is the age of cloud computing, we will be deploying our application to a cloud provider—Heroku, to be specific. Before we go on and deploy our application into production, we need to make sure our application is production-ready in our local environment. It would also be beneficial to make ourselves familiar with technologies and tools that will be useful at this stage.

In this chapter, we will learn about the following:

• Introduction to Docker
• Starting the production database with Docker
• Introducing Spring profiles
• Packaging the application for local deployment
• Upgrading to the newest version of JHipster
• Introducing the deployment options supported by JHipster
• Production deployment to the Heroku Cloud
