+# customer-helidon
+
+Helidon MP version of the "customer" microservice.
+
+## Build and run
+
+
+With JDK21
+```bash
+mvn package
+java -jar target/customer-helidon.jar
+```
+
+## Exercise the application
+
+Basic:
+```
+curl -X GET http://localhost:8080/simple-greet
+Hello World!
+```
+
+
+JSON:
+```
+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
+
+```
+curl -s -X GET http://localhost:8080/health
+{"outcome":"UP",...
+
+```
+
+
+## Building a Native Image
+
+The generation of native binaries requires an installation of GraalVM 22.1.0+.
+
+You can build a native binary using Maven as follows:
+
+```
+mvn -Pnative-image install -DskipTests
+```
+
+The generation of the executable binary may take a few minutes to complete depending on
+your hardware and operating system. When completed, the executable file will be available
+under the `target` directory and be named after the artifact ID you have chosen during the
+project generation phase.
+
+
+
+## Try metrics
+
+```
+# 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":...
+. . .
+```
+
+
+
+## Building the Docker Image
+
+```
+docker build -t customer-helidon .
+```
+
+## Running the Docker Image
+
+```
+docker run --rm -p 8080:8080 customer-helidon:latest
+```
+
+Exercise the application as described above.
