kubernetes-quickstart Project

This project uses Quarkus, the Supersonic Subatomic Java Framework.

If you want to learn more about Quarkus, please visit its website: https://quarkus.io/ .

Deploy to k3d

Create a cluster:

k3d  cluster create demo --api-port 6550  --port 8080:80@loadbalancer

build image:

docker build -f src/main/docker/Dockerfile.jvm -t svenschober/kubernetes-quickstart:1.0.0-SNAPSHOT .

import image:

k3d image import --cluster demo svenschober/kubernetes-quickstart:1.0.0-SNAPSHOT

adapt kubernetes.yml to use correct image name and set pull policy to NotIfPresent.
create deployment:

kubectl apply -f target/kubernetes/kubernetes.yml

create ingress

kubectl apply -f ingress.yml

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.

Creating a native executable

You can create a native executable using:

./mvnw package -Pnative

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

./mvnw package -Pnative -Dquarkus.native.container-build=true

You can then execute your native executable with: ./target/kubernetes-quickstart-1.0.0-SNAPSHOT-runner

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