## features

* native app

* global headers

* mustache reactive vertx handlebars templating

* build and push docker images by using fabric8 docker-maven-plugin

* correct docker container CMD and ENTRYPOINT usage

* application is running in docker with qaurkus user

* k3d / k3s k8s CI / local testing

* k3d / k3s import-images from local docker [k3d import-images feature introduced by PR #83, works with rancher/k3s tag of v0.7.0-rc2 or later due to a hard requirement on ctr inside the k3s](https://github.com/rancher/k3d/releases/tag/v1.3.0-dev.0)
