Description
Welcome to K8s Native Microservices on Quarkus course.

This course works on the latest versions of software as of July 2022

This course is intended for developers who are already familiar with Microservices and wish to implement them on Quarkus.

Equally, Quarkus developers willing to build micro-services can benefit by going through the lectures in this course. The course covers creating new microservices on Quarkus and deploying them to the Kubernetes environment as docker images or pods.

Working through a combination of theoretical concepts and practical code walkthroughs, a developer should follow along and build as we go through the lectures.

We will start our journey with basic concepts of JVM, why we need native deployable and the use of GraalVM. Then we build our first micro-service on Quarkus runtime, test it using RestAssured and deploy that on Minikube.

Our microservice will be able to handle all HTTP methods GET, PUT, POST and DELETE and later, we will connect it to an external database.

Then for our next section, we build another microservice and make it a dependency for the initial one. We mock this service in our primary service to test the behaviour, deploy both services in Minikube and see them in action.

Finally, we add health checks for liveness and readiness for each service and monitor our services' health and performance.

The course material will be your guide along the way providing relevant commands, steps of execution and references to learn more about the topic.
