This project uses Quarkus, the Supersonic Subatomic Java Framework.
If you want to learn more about Quarkus, please visit its website: https://quarkus.io/ .
The default application.properties expects you to have a postgresql database running. Hopefully you have docker installed then you can run the script in the repo home
./start-database.sh
You can run your application in dev mode that enables live coding using:
./mvnw quarkus:dev
also notice the %dev in the application.properties which means that the %.dev is only when you run in dev mode. the other properties will be used in openshift.
The application can be packaged using ./mvnw package.
It produces the quarkus-getting-started-1.0.0-SNAPSHOT-runner.jar file in the /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/quarkus-getting-started-1.0.0-SNAPSHOT-runner.jar.
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/quarkus-getting-started-1.0.0-SNAPSHOT-runner
If you want to learn more about building native executables, please consult https://quarkus.io/guides/building-native-image.
mvn quarkus:add-extension -Dextensions="openshift"
Login to openshift with the oc command
oc new-project quarkus-todo
Use the following command to create a postgresql database in your openshift namespace
oc new-app \
-e POSTGRESQL_USER=restcrud \
-e POSTGRESQL_PASSWORD=restcrud \
-e POSTGRESQL_DATABASE=restcrud \
-e POSTGRESQL_MAX_CONNECTIONS=200 \
--name=postgres-database \
openshift/postgresql
And finally to deploy the application into Openshift
mvn clean package -Dquarkus.kubernetes.deploy=true
now point to /todo.html or /api for json and you would see the app response
