Guide to Quarkus on Kubernetes

Quarkus is usually described as a Kubernetes-native Java framework. It allows us to automatically generate Kubernetes resources based on the defaults and user-provided configuration. It also provides an extension for building and pushing container images. Quarkus can create a container image and push it to a registry before deploying the application to the target platform. It also provides an extension that allows developers to use Kubernetes ConfigMap as a configuration source, without having to mount them into the pod. We may use fabric8 Kubernetes Client directly to interact with the cluster, for example during JUnit tests.
