Know Your Countries Demo Application For Eclipse JKube

Running the application in dev mode

This project uses Quarkus, the Supersonic Subatomic Java Framework.

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

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

./mvnw quarkus:dev

You can access your application at localhost:8080 as usual. It brings up a basic form to enter country name and displays basic information about the country provided:

Packaging and running the application

The application is packageable using ./mvnw package. It produces the executable todo-app-1.0.0-SNAPSHOT-runner.jar file in /target directory. Be aware that it’s not an über-jar as the dependencies are copied into the target/lib directory.

The application is now runnable using java -jar target/todo-app-1.0.0-SNAPSHOT-runner.jar.

Creating a native executable

You can create a native executable using: ./mvnw package -Pnative.

Or you can use Docker to build the native executable using: ./mvnw package -Pnative -Dquarkus.native.container-build=true.

You can then execute your binary: ./target/todo-app-1.0.0-SNAPSHOT-runner

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