# Ping pong service
Example implementation of an application on GraalVM
The system consists of two microservices
Microservices communicate using gRPC
## Requirements
- Java 11
- Maven
- Docker
- [GraalVM](https://www.graalvm.org/downloads/) (optional)
- [Helm](https://helm.sh/ru/docs/intro/install/) (optional)
- [gRPCurl](https://github.com/fullstorydev/grpcurl) (optional)
- [Vegeta](https://github.com/tsenart/vegeta) (optional)
## Docker-compose
Start
```shell
docker-compose up --detach
```
Stop
```shell
docker-compose down
```
## Build native image
### If GraalVM is installed on your computer
```shell
./mvnw clean verify -Pnative
```
### If GraalVM is not on your computer
Create a Docker image
```shell
./mvnw clean verify -Pnative \
-Dquarkus.container-image.build=true \
-Dquarkus.native.container-build=true \
-Dquarkus.container-image.name=NAME_MY_IMAGE
```
Example
```shell
./mvnw clean verify -Pnative \
-Dquarkus.container-image.build=true \
-Dquarkus.native.container-build=true \
-Dquarkus.container-image.name=ping-pong-front:1
```
### If GraalVM is not on your computer and the computer does not have Internet access
Create a Docker image
We can download the image using the GraalVM compiler locally or point to a Docker registry mirror
```shell
./mvnw clean verify -Pnative \
-Dquarkus.container-image.build=true \
-Dquarkus.native.container-build=true \
-Dquarkus.container-image.name=NAME_MY_IMAGE \
-Dquarkus.container-image.image=IMAGE_WITH_GRAAL_VM
```
Example
```shell
./mvnw clean verify -Pnative \
-Dquarkus.container-image.build=true \
-Dquarkus.native.container-build=true \
-Dquarkus.container-image.name=ping-pong-front:1 \
-Dquarkus.container-image.image=registry.access.redhat.com/quarkus/mandrel-22-rhel8:22.3
```
## Build JDK version
You can test the system using the regular JDK version
```shell
./mvnw clean package
```
## Applications
### Front
The application responds to a REST request from the user
[Source](front/)
#### API
Example of REST requests in IDEA REST Client notation: [example](http/front.http)
##### cURL Example
Checking that the application is working
```shell
curl http://localhost:8080/api/v1/ping
```
Pass the request to the back service
```shell
curl http://localhost:8080/api/v1/ping
```
### Back
The application receives a gRPC request and responds with a delay
[Source](back/)
#### API
Example of REST requests in IDEA REST Client notation: [example](http/back.http)
##### cURL Example
Find out the current response time limits of the gRPC service
```shell
curl http://localhost:8080/bound
```
Setting response time limits
```shell
curl -d '{ "lower": 50, "upper": 200 }' http://localhost:8080/bound
```
##### gRPC
Description
```shell
grpcurl localhost:9000 list
grpcurl -plaintext localhost:9000 describe ru.sbrf.gwec.PingPong
grpcurl -plaintext localhost:9000 describe ru.sbrf.gwec.PingPong
grpcurl -plaintext localhost:9000 describe ru.sbrf.gwec.Msg
```
Request
```shell
grpcurl -plaintext -d '{"body": "PING"}' localhost:9000 ru.sbrf.gwec.PingPong/ping
```
## Helm-chart
### Install
```shell
helm install ping-pong helm/ping-pong
```
### Upgrade to JIT version
```shell
helm upgrade ping-pong helm/ping-pong --values helm/ping-pong/values/demo-jit.yaml
```
### Upgrade to GraalVM version
```shell
helm upgrade ping-pong helm/ping-pong --values helm/ping-pong/values/demo-native.yaml
```
### Uninstall
```shell
helm uninstall ping-pong
```
## Stress test
You can perform a stress test using [Vegeta](vegeta/lt.sh)
