We are excited to announce the release of our newest tutorial, A Technical Deep Dive on Liberty.

A Technical Deep Dive on Liberty is an end-to-end tutorial that walks you through how to develop and deploy cloud-native Java applications in Jakarta EE and MicroProfile. The tutorial is aimed at Java developers, from Liberty novices to those more experienced with writing applications to run on Liberty.

In A Technical Deep Dive on Liberty, you will learn how to:

  • Build a RESTful microservice on Liberty with Jakarta EE and MicroProfile.

  • Easily document your REST API for developers to consume your microservice.

  • Externalize your configuration to make your application portable and easier to update.

  • Persist data to a database.

  • Secure your application using JSON Web Tokens (JWT) so that only authenticated and authorized applications can request information from your microservice.

  • Add health checks to easily report the statuses of your microservice (for orchestration decision).

  • Provide metrics to monitor activity and performance of your application.

  • Build a container image for your Java microservice.

  • Deploy the container image to Kubernetes using the Open Liberty Operator.

  • Test your applications easily with containers (for true-to-production testing).

If you don’t want to worry about local setup and prerequisites, try A Technical Deep Dive on Liberty in our cloud-hosted environment.

Alternatively, if you prefer, you can complete A Technical Deep Dive on Liberty on your own laptop.
