# Helidon Standalone Quickstart SE Example
This project implements a simple Hello World REST service using Helidon SE with
a standalone Maven pom.
## Build and run
With JDK8+
```bash
mvn package
java -jar target/helidon-standalone-quickstart-se.jar
```
## Exercise the application
```
curl -X GET http://localhost:8080/greet
{"message":"Hello World!"}
curl -X GET http://localhost:8080/greet/Joe
{"message":"Hello Joe!"}
curl -X PUT -H "Content-Type: application/json" -d '{"greeting" : "Hola"}' http://localhost:8080/greet/greeting
curl -X GET http://localhost:8080/greet/Jose
{"message":"Hola Jose!"}
```
## Try health and metrics
```
curl -s -X GET http://localhost:8080/health
{"outcome":"UP",...
. . .
# Prometheus Format
curl -s -X GET http://localhost:8080/metrics
# TYPE base:gc_g1_young_generation_count gauge
. . .
# JSON Format
curl -H 'Accept: application/json' -X GET http://localhost:8080/metrics
{"base":...
. . .
```
## Build the Docker Image
```
docker build -t helidon-standalone-quickstart-se .
```
## Start the application with Docker
```
docker run --rm -p 8080:8080 helidon-standalone-quickstart-se:latest
```
Exercise the application as described above
## Deploy the application to Kubernetes
```
kubectl cluster-info # Verify which cluster
kubectl get pods # Verify connectivity to cluster
kubectl create -f app.yaml # Deply application
kubectl get service helidon-standalone-quickstart-se # Get service info
```
## Native image with GraalVM
GraalVM allows you to compile your programs ahead-of-time into a native
executable. See https://www.graalvm.org/docs/reference-manual/aot-compilation/
for more information.
You can build a native executable in 2 different ways:
* With a local installation of GraalVM
* Using Docker
### Local build
Download Graal VM at https://github.com/oracle/graal/releases, the versions
currently supported for Helidon is `19.1.1` and `19.2.0`.
```
# Setup the environment
export GRAALVM_HOME=/path
# build the native executable
mvn package -Pnative-image
```
You can also put the Graal VM `bin` directory in your PATH, or pass
`-DgraalVMHome=/path` to the Maven command.
See https://github.com/oracle/helidon-build-tools/tree/master/helidon-maven-plugin
for more information.
Start the application:
```
./target/helidon-standalone-quickstart-se
```
### Multi-stage Docker build
Build the "native" Docker Image
```
docker build -t helidon-standalone-quickstart-se-native -f Dockerfile.native .
```
Start the application:
```
docker run --rm -p 8080:8080 helidon-standalone-quickstart-se-native:latest
```
