# Kubernetes Native Java with Spring Boot
Demonstration of:
- Cloud native development with Spring Boot and Reactive Spring
- Containerization with Cloud Native Buildpacks
- Kubernetes deployment manifests, graceful shutdown, and health probes
- Spring Boot configuration through ConfigMaps
- Native executables with Spring Boot 3 and GraalVM
- Serverless applications on Knative
## Prerequisites
To run all the examples, you need to install the following tools:
* [Java 17](https://adoptium.net)
* [Docker](https://www.docker.com)
* [Kubernetes CLI](https://kubernetes.io/docs/tasks/tools/)
* [kind](https://kind.sigs.k8s.io/docs/)
Recommended tools:
* [Octant](https://octant.dev)
* [Knative CLI](https://knative.dev/docs/client/)
## Usage
Both Spring Boot applications can be run locally with this command:
```shell
$ ./gradlew bootRun
```
You can containerize them via Buildpacks. Book Service will be containerized as a JVM image, whereas Book Native will be containerized as a native image.
```shell
$ ./gradlew bootBuildImage
```
## Deployment on a local Kubernetes cluster
You can spin up a Kubernetes cluster as follows:
```shell
$ ./kind/create-cluster.sh
```
Then, deploy Book Service with kubectl:
```shell
$ kubectl apply demo-service/config
```
When you're done, you can destroy the cluster as follows:
```shell
$ ./kind/destroy-cluster.sh
```
## Deployment on a local Kubernetes cluster with Knative
You can spin up a Kubernetes cluster with Knative as follows:
```shell
$ ./kind/install-knative.sh
```
Then, deploy Book Native with kubectl:
```shell
$ kubectl apply demo-service/knative
```
