• 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
