-# rhbq17-native
+# rhbq17-native project
+
+This project showcases to package a native executable using Mandrel base image then deploy to OpenShift as Knative Service.
+
+If you want to learn more about Quarkus, please visit its website: https://access.redhat.com/documentation/en-us/red_hat_build_of_quarkus .
+
+## Running the application in dev mode
+
+You can run your application in dev mode that enables live coding using:
+```
+./mvnw quarkus:dev
+```
+
+## Edit an application.properties
+
+In order to package a native binary based on mandrel image:
+```
+quarkus.native.container-build=true
+quarkus.native.builder-image=quay.io/quarkus/ubi-quarkus-mandrel:20.1-java11
+```
+
+## Creating a native executable
+
+You can create a native executable using: `./mvnw package -Pnative`.
+
+## Build using OC CLI
+
+Make sure to log in the OpenShift Cluster. Then create a new project:
+
+```
+oc new-project rhbq17-native
+```
+
+Run the following commands:
+
+```
+oc new-build quay.io/quarkus/ubi-quarkus-native-binary-s2i:1.0 --binary --name=native -l app=native
+
+oc start-build native --from-file=target/rhbq17-native-1.0.0-SNAPSHOT-runner --follow
+```
+
+## Dev Console in OCP cluster
+
+Navigate Developer Console > +Add > Container Image then select `Image stream tag from internal registry`:
+
+ * Project : rhbq17-native
+ * ImageStreams : native
+ * Tag : latest
+
+Select `Knative Service` in Resources then click on `Create`.
+
+Once the Knative service is up in Topology view, click on `Open URL`. Then access the endpoint(i.e. _/hello_), you should see `hello`.
+
+## Change the code
+
+Open the `ExampleResource.java` then repalce `hello` with `Congrats! Red Hat Build Of Quarkus 1.7 GA!` in the return code.
+
+## Re-Build using OC CLI
+
+Make sure to log in the OpenShift Cluster. Run the following commands:
+```
+oc new-build quay.io/quarkus/ubi-quarkus-native-binary-s2i:1.0 --binary --name=native -l app=native-2
+
+oc start-build native-2 --from-file=target/rhbq17-native-1.0.0-SNAPSHOT-runner --follow
+```
+
+## Update the existing Knative Service using KN CLI
+
+Find the ImageStream that you just pushed:
+
+```
+oc get is
+```
+
+You should see like this:
+
+```

+
+Update the knative service:
+
+```
+kn service update native --image image-registry.openshift-image-registry.svc:5000/rhbq17-native/native-2:latest
+```
