This project uses Quarkus, the Supersonic Subatomic Java Framework.

Running the application in dev mode

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

./mvnw compile quarkus:dev

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

Packaging and running the application

The application can be packaged using:

./mvnw 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.

Manually create the database for local testing (with initialization file) ...

podman run -d --name pg-library-shop -p 5432:5432 \
    -e POSTGRES_USER=quarkus -e POSTGRES_PASSWORD=quarkus -e POSTGRES_DATABASE=quarkus \
    -v $PWD/src/main/database:/docker-entrypoint-initdb.d:ro,z \
    docker.io/library/postgres:17

Creating a native executable

You can create a native executable using:

./mvnw package -Dnative

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

./mvnw package -Dnative -Dquarkus.native.container-build=true -Dquarkus.native.container-runtime=podman

You can then execute your native executable with: ./target/library-shop-1.0.0-runner

If you want to learn more about building native executables, please consult https://quarkus.io/guides/maven-tooling.

Creating a Container image with your application

Create a Container image for the Java Virtual Machine

Manually

To create the container image review the file Containerfile.jvm

FROM registry.access.redhat.com/ubi9/openjdk-21-runtime:1.21-1

ENV LANGUAGE='en_US:en'


# We make four distinct layers so if there are application changes the library-shop layers can be re-used
COPY --chown=185 target/quarkus-app/lib/ /deployments/lib/
COPY --chown=185 target/quarkus-app/*.jar /deployments/
COPY --chown=185 target/quarkus-app/app/ /deployments/app/
COPY --chown=185 target/quarkus-app/quarkus/ /deployments/quarkus/

EXPOSE 8080
USER 185
ENV JAVA_OPTS_APPEND="-Dquarkus.http.host=0.0.0.0 -Djava.util.logging.manager=org.jboss.logmanager.LogManager"
ENV JAVA_APP_JAR="/deployments/quarkus-run.jar"

ENTRYPOINT [ "/opt/jboss/container/java/run/run-java.sh" ]

Execute the command :

podman build -f ./src/main/docker/Containerfile.jvm -t rha/library-shop:1.0.0 .

Via Quarkus Building Container Extension

Using jib (quarkus-container-image-jib) extension

./mvnw package -Pjib

Check the iamge

podman run --rm -it -e DATABASE_HOST=alumno -p 8080:8080 rha/library-shop-jib:1.0.0

Using docker (quarkus-container-image-docker) extension

./mvnw package -Pdocker

Check the iamge

podman run --rm -it -e DATABASE_HOST=alumno -p 8080:8080 rha/library-shop-docker:1.0.0

Create a Container image for the native executable

FROM registry.access.redhat.com/ubi9/ubi-micro:9.5-1733126338
WORKDIR /work/
RUN chown 1001 /work \
    && chmod "g+rwX" /work \
    && chown 1001:root /work
COPY --chown=1001:root target/*-runner /work/application

EXPOSE 8080
USER 1001

CMD ["./application", "-Dquarkus.http.host=0.0.0.0"]

Deploying application to OpenShift Platform

Development using JKube openshift-maven-plugin

Launch an application build

mvn package oc:build -DskipTests -Djkube.docker.verbose

Launch the deploy

mvn package oc:resource oc:apply -DskipTests

Launch a rollout

mvn oc:rollout

Library Shop Application API

Check the application OpenAPI specification

http://localhost:8080/q/swagger-ui

curl -i -X POST http://localhost:8080/library -H "Content-type: application/json" -d '{"title":"The Difference Engine","year":1990,"isbn":"0-575-04762-3","price":12.0,"authors":[{"name":"William Gibson"},{"name":"Bruce Sterling"}]}'

Get a book by Id

curl -s http://localhost:8080/library/1 | jq

Update the book price

curl -i -X PUT http://localhost:8080/library/1/price\?price\=15.00

Paged list all the books

curl -s http://localhost:8080/library/ | jq
