# Kong Ingress Controller with Spring Boot
|
||
|
|
|
||
|
|
This project was generated from Spring Initializer Website (https://start.spring.io/):
|
||
|
|
|
||
|
|
Maven version Java latest:
|
||
|
|
```
|
||
|
|
curl https://start.spring.io/starter.tgz -d dependencies=webflux,actuator -d type=maven-project | tar -xzvf -
|
||
|
|
```
|
||
|
|
|
||
|
|
Maven version Java 11:
|
||
|
|
```
|
||
|
|
curl https://start.spring.io/starter.tgz -d dependencies=webflux,actuator -d type=maven-project -d javaVersion=11 | tar -xzvf -
|
||
|
|
```
|
||
|
|
|
||
|
|
## Steps to run the demonstration:
|
||
|
|
|
||
|
|
1. Install minikube: https://www.baeldung.com/spring-boot-minikube
|
||
|
|
|
||
|
|
2. Install Kong Ingress Controller on minikube: https://docs.konghq.com/kubernetes-ingress-controller/latest/deployment/minikube/
|
||
|
|
- Test wich echo-server
|
||
|
|
- Create environment variable: export PROXY_IP=$(minikube service -n kong kong-proxy --url | head -1)
|
||
|
|
|
||
|
|
3. build that Spring boot service:
|
||
|
|
- Run ./mvnw install
|
||
|
|
- Run jar: java -jar target/*.jar
|
||
|
|
|
||
|
|
4. Create a Docker image:
|
||
|
|
If using minikube and don't want to push image to a repository, then point your local Docker client to Minikube's implementation: eval $(minikube -p minikube docker-env) --- use the same shell.
|
||
|
|
- Run: ./mvnw spring-boot:build-image
|
||
|
|
|
||
|
|
5. Deploy the application, create a service and an ingress rule:
|
||
|
|
```
|
||
|
|
kubectl apply -f serviceDeployment.yaml
|
||
|
|
kubectl apply -f clusterIp.yaml
|
||
|
|
kubectl apply -f ingress-rule.yaml
|
||
|
|
```
|
||
|
|
|
||
|
|
6. Test access using the proxy IP:
|
||
|
|
```
|
||
|
|
curl -i $PROXY_IP/actuator/health
|
||
|
|
```
|
||
|
|
|
||
|
|
## Setting up a rate limiter on your api
|
||
|
|
|
||
|
|
7. Create a plugin:
|
||
|
|
|
||
|
|
kubectl apply -f rate-limiter.yaml
|
||
|
|
|
||
|
|
8. Now test resource. Try more than 5 times a minute:
|
||
|
|
```
|
||
|
|
curl -i $PROXY_IP/actuator/health
|
||
|
|
```
|
||
|
|
|
