# Spring Boot Kubernetes
Sample project to use spring boot application in kubernetes with jkube maven plugin.
* Build application
```shell
mvn clean package
```
## Docker image with layered architecture
For docker image with layered architecture, refer [Jenkinsfile](./Jenkinsfile) and [Dockerfile](./deploy/Dockerfile)
directory.
* Open shell in project directory and run following command to build docker image.
```shell
docker build -f deploy/Dockerfile --build-arg VERSION=7.2.0 -t ashutoshsahoo/spring-boot-kubernetes:7.2.0 .
```
## Kubernetes deployment
* Deploy to kubernetes
```shell
kubectl apply -f deploy/kubernetes.yml
```
* Check pod and service status
```sh
kubectl get po,svc
```
* Verify application status
```sh
curl --location --request GET 'http://localhost:31000/api/v5/hello'
```
* Delete Kubernetes deployment
```shell
kubectl delete -f deploy/kubernetes.yml
```
## Kubernetes Istio service mesh deployment
This is a demonstration of running two different versions of same application and redirecting traffic based on path
prefix.
Please follow the instructions [here](https://istio.io/latest/docs/setup/getting-started/) to configure istio inside
docker desktop.
* Deploy app
```shell
kubectl apply -f deploy/istio
```
* Check application status
```sh
kubelet get all
```
* Verify application status
```sh
curl --location --request GET 'http://localhost/api/v5/hello'
```
* Run following command to put some traffic into system.
```shell
for i in $(seq 1 100); do curl -s -o /dev/null "http://localhost/api/v5/hello"; done
for i in $(seq 1 100); do curl -s -o /dev/null "http://localhost/api/v6/hello"; done
```
Open [kiali dashboard](http://localhost:20001/kiali) to view application metrics.
* Delete deployment
```shell
kubectl delete -f deploy/istio
```
* Clean up istio configuration
Refer the documentation [here](https://istio.io/latest/docs/setup/getting-started/#uninstall) to clean up.
## Deploy application using jkube maven plugin
* Application deployment
```shell
mvn -Pk8s k8s:build k8s:resource k8s:deploy
```
* Verify application
```sh
kubectl exec -it deployments.apps/spring-boot-kubernetes -- bash
curl --location --request GET 'http://localhost:8080/api/v5/hello'
```
* UnDeploy application
```shell
mvn -Pk8s k8s:undeploy
```
