This project uses Quarkus, the Supersonic Subatomic Java Framework. If you want to learn more about Quarkus, please visit its website: https://quarkus.io/ .

First run your Docker Daemon. The following command should be succeeded:

docker ps

You can run your application in dev mode that enables live coding using:

mvn compile quarkus:dev

NOTE: Quarkus now ships with a Dev UI, which is available in dev mode only at http://localhost:8080/q/dev/.

The application can be packaged using:

mvn clean package

It produces the quarkus-run.jar file in the target/quarkus-app/ directory. Be aware that it’s not an über-jar as the dependencies are copied into the target/quarkus-app/lib/ directory.

The application is now runnable using java -jar target/quarkus-app/quarkus-run.jar.

If you want to build an über-jar, execute the following command:

./mvnw package -Dquarkus.package.type=uber-jar

The application, packaged as an über-jar, is now runnable using java -jar target/*-runner.jar.

You can create a native executable using:

mvn package -Pnative

Or, if you don't have GraalVM installed, you can run the native executable build in a container using:

mvn package -Pnative -Dquarkus.native.container-build=true

You can then execute your native executable with: ./target/sample-quarkus-microservice-1.0.0-SNAPSHOT-runner

First, you need to install Postgres on Kubernetes, e.g. with Helm:

$ helm install person-db bitnami/postgresql -n sample-quarkus --set auth.username=quarkus  --set auth.database=quarkus --set fullnameOverride=person-db --create-namespace

Then, you can build and deploy the app within one step with Maven by activating the kubernetes profile:

$ QUARKUS_JIB_BASE_JVM_IMAGE=registry.access.redhat.com/ubi8/openjdk-17-runtime:latest  mvn clean package -DskipTests -Pkubernetes

Or, with the minikube profile for running on Minikube.
